| 1 | A Collinearity-Incorporating Homology Inference Strategy for Connecting Emerging Assemblies in the Triticeae Tribe as a Pilot Practice in the Plant Pangenomic Era显示文摘Plant genome sequencing has dramatically increased,and some species even have multiple high-quality reference versions.Demands for clade-specific homology inference and analysis have increased in the pangenomic era.Here we present a novel method,GeneTribe(http://gffzz6c7fcf032cb94ff5sb95obvuuvcvp69un.ffgz.tsg.suse.edu.cn/genetribe/),for homology inference among genetically similar genomes that incorporates gene collinearity and shows bet-ter performance than traditional sequence-similarity-based methods in terms of accuracy and scalability.The Triticeae tribe is a typical allopolyploid-rich clade with complex species relationships that includes many important crops,such as wheat,barley,and rye.We built Triticeae-GeneTribe(http://gffzzaeec8df70e7c4b21hb95obvuuvcvp69un.ffgz.tsg.suse.edu.cn/TGT/),a homology database,by integrating 12 Triticeae genomes and 3 outgroup model genomes and implemented versatile analysis and visualization functions.With macrocollinearity analysis,we were able to construct a refined model illustrating the structural rearrangements of the 4A-5A-7B chromosomes in wheat as two major translocation events.With collinearity analysis at both the macro-and microscale,we illustrated the complex evolutionary history of homologs of the wheat vernalization gene Vm2,which evolved as a combined result of genome translocation,duplication,and polyploidization and gene loss events.Our work provides a useful practice for connecting emerging genome assemblies,with awareness of the extensive polyploidy in plants,and will help researchers efficiently exploit genome sequence re-sources. | Yongming Chen Wanjun Song Xiaoming Xie Zihao Wang Panfeng Guan Huiru Peng Yuannian Jiao Zhongfu Ni Qixin Sun Weilong Guo | 2020 | Molecular Plant2020,13,12: | 14 |
| 2 | A natural variation in Ribonuclease H-like gene underlies Rht8 to confer“Green Revolution”trait in wheat显示文摘Dear Editor,Introduction of gibberellin(GA)-insensitive Reduced height(Rht)genes,Rht-B1b and Rht-D1b,has resulted in the“Green Revolution”in modern wheat cultivars(Triticum aestivum)that has skyrocketed wheat grain yields worldwide since the 1960s(Peng et al.,1999;Velde et al.,2021).However,Rht-B1b/D1b also reduce coleoptiles,which is undesired in dryland regions where deep planting is essential for seedling establishment(Rebetzke et al.,1999,Rebetzke et al.,2001;Ellis et al.,2004). | Lingling Chai Mingming Xin Chaoqun Dong Zhaoyan Chen Huijie Zhai Junhong Zhuang Xuejiao Cheng Naijiao Wang Jia Geng Xiaobo Wang Ruolin Bian Yingyin Yao Weilong Guo Zhaorong Hu Huiru Peng Guihua Bai Qixin Sun Zhenqi Su Jie Liu Zhongfu Ni | 2022 | Molecular Plant2022,15,3: | 8 |
| 3 | Ectopic expression of VRT-A2 underlies the origin of Triticum polonicum and Triticum petropavlovskyi with long outer glumes and grains显示文摘Polish wheat (Triticum polonicum) is a unique tetraploid wheat species characterized by an elongated outer glume. The genetic control of the long-glume trait by a single semi-dominant locus, P1 (from Polish wheat), was established more than 100 years ago, but the underlying causal gene and molecular nature remain elusive. Here, we report the isolation of VRT-A2, encoding an SVP-clade MADS-box transcription factor, as the P1 candidate gene. Genetic evidence suggests that in T. polonicum, a naturally occurring sequence rearrangement in the intron-1 region of VRT-A2 leads to ectopic expression of VRT-A2 in floral organs where the long-glume phenotype appears. Interestingly, we found that the intron-1 region is a key ON/OFF molecular switch for VRT-A2 expression, not only because it recruits transcriptional repressors, but also because it confers intron-mediated transcriptional enhancement. Genotypic analyses using wheat accessions indicated that the P1 locus is likely derived from a single natural mutation in tetraploid wheat, which was subsequently inherited by hexaploid T. petropavlovskyi. Taken together, our findings highlight the promoter-proximal intron variation as a molecular basis for phenotypic differentiation, and thus species formation in Triticum plants. | Jing Liu Zhaoyan Chen Zhihui Wang Zhaoheng Zhang Xiaoming Xie Zihao Wang Lingling Chai Long Song Xuejiao Cheng Man Feng Xiaobo Wang Yanhong Liu Zhaorong Hu Jiewen Xing Zhenqi Su Huiru Peng Mingming Xin Yingyin Yao Weilong Guo Qixin Sun Jie Liu Zhongfu Ni | 2021 | Molecular Plant2021,14,9: | 4 |
| 4 | A wheat integrative regulatory network from large-scale complementary functional datasets enables trait-associated gene discovery for crop improvement显示文摘Gene regulation is central to all aspects of organism growth,and understanding it using large-scale functional datasets can provide a whole view of biological processes controlling complex phenotypic traits in crops.However,the connection between massive functional datasets and trait-associated gene discovery for crop improvement is still lacking.In this study,we constructed a wheat integrative gene regulatory network(wGRN)by combining an updated genome annotation and diverse complementary functional datasets,including gene expression,sequence motif,transcription factor(TF)binding,chromatin accessibility,and evolutionarily conserved regulation.wGRN contains 7.2 million genome-wide interactions covering 5947 TFs and 127439 target genes,which were further verified using known regulatory relationships,condition-specific expression,gene functional information,and experiments.We used wGRN to assign genome-wide genes to 3891 specific biological pathways and accurately prioritize candidate genes associated with complex phenotypic traits in genome-wide association studies.In addition,wGRN was used to enhance the interpretation of a spike temporal transcriptome dataset to construct high-resolution networks.We further unveiled novel regulators that enhance the power of spike phenotypic trait prediction using machine learning and contribute to the spike phenotypic differences among modern wheat accessions.Finally,we developed an interactive webserver,wGRN(http://gffzzaeec8df70e7c4b21hb95obvuuvcvp69un.ffgz.tsg.suse.edu.cn/wGRN),for the community to explore gene regulation and discover trait-associated genes.Collectively,this community resource establishes the foundation for using large-scale functional datasets to guide trait-associated gene discovery for crop improvement. | Yongming Chen Yiwen Guo Panfeng Guan Yongfa Wang Xiaobo Wang Zihao Wang Zhen Qin Shengwei Ma Mingming Xin Zhaorong Hu Yingyin Yao Zhongfu Ni Qixin Sun Weilong Guo Huiru Peng | 2023 | Molecular Plant2023,16,2: | 1 |

| 8 | Bioinspired Injectable Self-Healing Hydrogel Sealant with Fault-Tolerant and Repeated Thermo-Responsive Adhesion for Sutureless Post-Wound-Closure and Wound Healing显示文摘Hydrogels with multifunctionalities,including sufficient bonding strength,injectability and self-healing capacity,responsive-adhesive ability,fault-tolerant and repeated tissue adhesion,are urgently demanded for invasive wound closure and wound healing.Motivated by the adhesive mechanism of mussel and brown algae,bioinspired dynamic bonds cross-linked multifunctional hydrogel adhesive is designed based on sodium alginate(SA),gelatin(GT)and protocatechualdehyde,with ferric ions added,for sutureless post-wound-closure.The dynamic hydrogel cross-linked through Schiff base bond,catechol-Fe coordinate bond and the strong interaction between GT with temperature-dependent phase transition and SA,endows the resulting hydrogel with sufficient mechanical and adhesive strength for efficient wound closure,injectability and self-healing capacity,and repeated closure of reopened wounds.Moreover,the temperature-dependent adhesive properties endowed mispositioning hydrogel to be removed/repositioned,which is conducive for the fault-tolerant adhesion of the hydrogel adhesives during surgery.Besides,the hydrogels present good biocompatibility,near-infrared-assisted photothermal antibacterial activity,antioxidation and repeated thermo-responsive reversible adhesion and good hemostatic effect.The in vivo incision closure evaluation demonstrated their capability to promote the post-wound-closure and wound healing of the incisions,indicating that the developed reversible adhesive hydrogel dressing could serve as versatile tissue sealant. | Yuqing Liang Huiru Xu Zhenlong Li Aodi Zhangji Baolin Guo | 2022 | Nano-Micro Letters2022,14,11: | 1 |
| 9 | Sequencing and comparative analyses of Aegilops tauschii chromosome arm 3DS reveal rapid evolution of Triticeae genomes显示文摘Bread wheat(Triticum aestivum,AABBDD) is an allohexaploid species derived from two rounds of interspecific hybridizations.A high-quality genome sequence assembly of diploid Aegilops tauschii,the donor of the wheat D genome,will provide a useful platform to study polyploid wheat evolution.A combined approach of BAC pooling and next-generation sequencing technology was employed to sequence the minimum tiling path(MTP) of 3176 BAC clones from the short arm of Ae.tauschii chromosome 3(At3DS).The final assembly of 135 super-scaffolds with an N50 of 4.2 Mb was used to build a247-Mb pseudomolecule with a total of 2222 predicted protein-coding genes.Compared with the orthologous regions of rice,Brachypodium,and sorghum,At3 DS contains 38.67%more genes.In comparison to At3 DS,the short arm sequence of wheat chromosome 3B(Ta3BS) is 95-Mb large in size,which is primarily due to the expansion of the non-centromeric region,suggesting that transposable element(TE) bursts in Ta3 B likely occurred there.Also,the size increase is accompanied by a proportional increase in gene number in Ta3 BS.We found that in the sequence of short arm of wheat chromosome 3D(Ta3DS),there was only less than 0.27%gene loss compared to At3 DS.Our study reveals divergent evolution of grass genomes and provides new insights into sequence changes in the polyploid wheat genome. | Jingzhong Xie Naxin Huo Shenghui Zhou Yi Wang Guanghao Guo Karin R.Deal Shuhong Ouyang Yong Liang Zhenzhong Wang Lichan Xiao Tingting Zhu Tiezhu Hu Vijay Tiwari Jianwei Zhang Hongxia Li Zhongfu Ni Yingyin Yao Huiru Peng Shengli Zhang Olin D.Anderson Patrick E.McGuire Jan Dvorak Ming-Cheng Luo Zhiyong Liu Yong Q.Gu Qixin Sun | 2017 | Journal of Genetics and Genomics2017,44,1: | 1 |
| 10 | Concurrent silencing of TBCE and drug delivery to overcome platinum-based resistance in liver cancer显示文摘Platinum-based chemotherapy resistance is a key factor of poor prognosis and recurrence in hepatocellular carcinoma(HCC).Herein,RNAseq analysis revealed that elevated tubulin folding cofactor E(TBCE)expression is associated with platinum-based chemotherapy resistance.High expression of TBCE contributes to worse prognoses and earlier recurrence among liver cancer patients.Mechanistically,TBCE silencing significantly affects cytoskeleton rearrangement,which in turn increases cisplatin-induced cycle arrest and apoptosis.To develop these findings into potential therapeutic drugs,endosomal pH-responsive nanoparticles(NPs)were developed to simultaneously encapsulate TBCE siRNA and cisplatin(DDP)to reverse this phenomena.NPs(siTBCE+DDP)concurrently silenced TBCE expression,increased cell sensitivity to platinum treatment,and subsequently resulted in superior anti-tumor effects both in vitro and in vivo in orthotopic and patient-derived xenograft(PDX)models.Taken together,NP-mediated delivery and the co-treatment of siTBCE+DDP proved to be effective in reversing chemotherapy resistance of DDP in multiple tumor models. | Senlin Li Siyu Chen Zhihui Dong Xingdong Song Xiuling Li Ziqi Huang Huiru Li Linzhuo Huang Ganyuan Zhuang Ran Lan Mingyan Guo Wende Li Phei Er Saw Lei Zhang | 2023 | Acta Pharmaceutica Sinica B2023,13,3: | 1 |
| 11 | Genome-wide linkage mapping of QTL for root hair length in a Chinese common wheat population显示文摘Root hairs are fast growing,ephemeral tubular extensions of the root epidermis that aid nutrient and water uptake.The aim of the present study was to identify QTL for root hair length(RHL)using 227 F8 recombinant inbred lines(RILs)derived from a cross of Zhou 8425 B(Z8425 B)and Chinese Spring(CS),and to develop convenient molecular markers for markerassisted breeding in wheat.Analysis of variance of root hair length showed significant differences(P<0.01)among RILs.The genetic map for QTL analysis consisted of 3389 unique SNP markers.Using composite interval mapping,four major QTL(LOD>2.5)for RHL were identified on chromosomes 1 B(2),2 D and 6 D and four putative QTL(2≤LOD≤2.5)were detected on chromosomes 1 A,3 A,6 B,and 7 B,explaining 3.32%–6.52%of the phenotypic variance.The positive alleles for increased RHL of QTL on chromosomes 2 D,6 B and 6 D(QRhl.cau-2 D,q Rhl.cau-6 B,and QRhl.cau-6 D)were contributed by Z8425 B,and CS contributed positive QTL alleles on chromosomes 1 A(q Rhl.cau-1 A),1 B(QRhl.cau-1 B.1 and QRhl.cau-1 B.2),3 A(q Rhl.cau-3 A)and 7 B(q Rhl.cau-7 B).STARP markers were developed for QRhl.cau-1 B.1,QRhl.cau-2 D,QRhl.cau-6 D,and q Rhl.cau-7 B.Haplotype and association analysis indicated that the positive allele of QRhl.cau-6 D had been strongly selected in Chinese wheat breeding programs.Collectively,the identified QTL for root hair length are likely to be useful for marker-assisted selection. | Feng Huang Zhaoyan Chen Dejie Du Panfeng Guan Lingling Chai Weilong Guo Zhaorong Hu Mingming Xin Huiru Peng Yingyin Yao Zhongfu Ni | 2020 | The Crop Journal2020,8,6: | 0 |
| 12 | The bone alterations in hind limb amputation rats in vivo显示文摘Osteoporosis,which is characterized by bone loss,increases the risk of fractures and s and seriously affected the amputee’s health.Muscle mass is an important factor affecting bone mineral density(BMD).Muscular atrophy and decreased muscle mass can cause BMD to fall.The bone quantity and quality are used to assess by Microcomputer tomography(micro-CT)with non-destructive.To investigate the performance of micro-CT in evaluating amputation-induced osteopenia in rats,the micro-CT was used to evaluate the change of the microstructure in trabecular bone and cortical bone of amputation.Muscle morphology was analyzed by micro-CT and transmission electron microscopy.Female Sprague–Dawley rats(8 week old)were divided into two groups:control(CON)groups and left hind limb amputation(LHLA).At 35 days,microstructure and volumetric bone mineral density(vBMD)of the tibia and femur were detected through micro-CT.The results showed:(1)the trabecular and cortical vBMD of the proximal tibia and distal femur in the LHLA group were significantly lower than those in the CON group.(2)Compared with the CON group,the trabecular number,bone volume fraction and trabecular thickness of proximal tibia and distal femur in LHLA group decreased significantly,whereas the trabecular separation,structure model index and bone surface/bone volume increased significantly in LHLA group.(3)The whole cross-sectional area(CSA)of whole calf muscles of left limb in LHLA group decreased significantly compared with CON group.In general,hind limb amputation could cause bone loss,changes in the microstructure of trabecular bone and muscle atrophy.Micro-CT is sensitive in evaluating bone microstructure destruction caused by amputation,and can be used for early diagnosis or monitor the development of bone loss in amputation in vivo. | Huiqin Luan Huiru gu Zhongjun Mo Weiyan Ren Huan Guo Zhaowei Chu Yubo Fan | 2020 | Medicine in Novel Technology and Devices2020,,4: | 0 |
| 13 | Deciphering the evolution and complexity of wheat germplasm from a genomic perspective显示文摘Bread wheat provides an essential fraction of the daily calorific intake for humanity.Due to its huge and complex genome,progress in studying on the wheat genome is substantially trailed behind those of the other two major crops,rice and maize,for at least a decade.With rapid advances in genome assembling and reduced cost of high-throughput sequencing,emerging de novo genome assemblies of wheat and whole-genome sequencing data are leading to a paradigm shift in wheat research.Here,we review recent progress in dissecting the complex genome and germplasm evolution of wheat since the release of the first high-quality wheat genome.New insights have been gained in the evolution of wheat germplasm during domestication and modern breeding progress,genomic variations at multiple scales contributing to the diversity of wheat germplasm,and complex transcriptional and epigenetic regulations of functional genes in polyploid wheat.Genomics databases and bioinformatics tools meeting the urgent needs of wheat ge-nomics research are also summarized.The ever-increasing omics data,along with advanced tools and well-structured databases,are expected to accelerate deciphering the germplasm and gene resources in wheat for future breeding advances. | Zihao Wang Lingfeng Miao Yongming Chen Huiru Peng Zhongfu Ni Qixin Sun Weilong Guo | 2023 | Journal of Genetics and Genomics2023,50,11: | 0 |
| 14 | A highly conserved amino acid in high molecular weight glutenin subunit 1Dy12 contributes to gluten functionality and processing quality in wheat显示文摘Bread wheat(Triticum aestivum L.)is one of the most commonly consumed staples worldwide,with widespread uses in foods such as breads,noodles,cakes,and cookies(Veraverbeke and Delcour,2002).The specific cooking properties of wheat products are mainly conferred by the gluten proteins contained in wheat grains(Delcour et al.,2012).High molecular weight glutenin subunits(HMW-GSs)are important constituents of wheat gluten proteins,largely determining gluten elasticity and processing quality(Branlard and Dardevet,1985;Payne et al.,1988). | Changfeng Yang Qian Chen Mingming Xin Zhenqi Su Jinkun Du Weilong Guo Zhaorong Hu Jie Liu Huiru Peng Zhongfu Ni Qixin Sun Yingyin Yao | 2023 | Journal of Genetics and Genomics2023,50,11: | 0 |
| 15 | TaANR1-TaMADS25 module regulates lignin biosynthesis and root development in wheat(Triticum aestivum L.)显示文摘Common wheat is a staple food for 35%of the global population,therefore increasing wheat yield in an ever-changing environment is essential for food security in the present day(Peng et al.,2011).Root system is responsible for water and nutrient acquisition,thus crucial for competitive fitness and crop yield in challenging environments(Karlova et al.,2021;Liu et al.,2022).Over the past decades,extensive research has focused on identifying genes accountable for root growth and development in plants(Rogers and Benfey,2015).However,only a limited number of genes have been cloned in wheat(Li et al.,2021). | Weiya Xu Yongming Chen Bin Liu Qiuyuan Li Yilan Zhou Xuanshuang Li Weilong Guo Zhaorong Hu Zhenshan Liu Mingming Xin Yingyin Yao Mingshan You Huiru Peng Zhongfu Ni Jiewen Xing | 2023 | Journal of Genetics and Genomics2023,50,11: | 0 |
| 16 | Relationships between selfreflectiveness and clinical symptoms in individuals during pre-morbid and early clinical stages of psychosis显示文摘Background Self-reflectiveness,one dimension of cognitive insight,plays a protective role in an individual’s mental state.Both high and low levels of self-reflectiveness have been reported in patients with schizophrenia and individuals at clinical high risk for the illness.Aims This study aimed to explore the relationship patterns between self-reflectiveness and clinical symptoms in individuals during the pre-morbid and early clinical stages of psychosis.Methods A total of 181 subjects,including individuals with attenuated positive symptoms(APS,n=122)and patients with first-episode psychosis(FEP,n=59),completed the Beck Cognitive Insight Scale and were evaluated using the Schedule of Assessment of Insight and Positive and Negative Syndrome Scale.All subjects were classified into three groups according to their level of selfreflectiveness:low level(LSR,n=59),medium level(MSR,n=67)and high level(HSR,n=55).Both linear and nonlinear relationships between self-reflectiveness and clinical symptoms were explored.Results More individuals with APS were classified into the MSR group,while more patients with FEP were classified into the LSR group.The LSR group demonstrated less awareness of illness than the MSR and HSR groups,more stereotyped thinking and poorer impulse control but less anxiety than the MSR group,and lower levels of blunted affect and guilt feelings than the HSR group.The MSR group demonstrated lower stereotyped thinking than the HSR group.Compared to the LSR group,the MSR group had increased selfreflectiveness,improved awareness of illness,decreased stereotyped thinking,and better impulse control,but increased feelings of guilt.The HSR group showed increased stereotyped thinking when compared to the MSR group,but the other variables did not change significantly between these two groups.Overall,self-reflectiveness demonstrated an approximately inverse S-shaped relationship with the awareness of illness,a U-shaped relationship with stereotyped thinking and poor impulse control,and an almost linear relationship with anxiety and guilt feelings.Conclusions Self-reflectiveness demonstrates complex relationships with clinical symptoms and fails to exert significant positive effects when reaching a certain high level. | Lihua Xu Huiru Cui Yanyan Wei Zhenying Qian Xiaochen Tang Yegang Hu Yingchan Wang Hao Hu Qian Guo Yingying Tang Tianhong Zhang Jijun Wang | 2022 | General Psychiatry2022,35,3: | 0 |
| 17 | Effects of vitamin C on the structural and functional characteristics of wheat gluten显示文摘Vitamin C(VC)can greatly enhance the quality properties of dough and steamed bread in the food field.However,there are few studies on the interaction between VC and gluten,and the mechanism of VC influencing the foaming capacity,emulsifiablity,and dynamic viscosity of gluten is not clear.In this study,different content of VC(0,1%,2%,3%,4%and 5%)was added to gluten to obtain VC-gluten dough samples(CK,GV1,GV2,GV3,GV4 and GV5),and the properties of the VC-gluten dough were determined.Results showed that the increasing VC content lead to increase in the content of high-,medium-and low-molecular weight gluten,suggesting that VC improved the protein solubility of gluten.The G'and G'values of dough containing VC were higher than those of the control with the increase of scanning frequency.The foaming ability of gluten increased with the increase of VC content.Emulsibility of the dough of GV1 to GV 5 were significantly lower than that of the CK.Furthermore,VC could reduce the number of bubbles in gluten protein,when the VC content was less than 3%.In conclusion,VC might reduce the emulsifying characteristic and emulsifying stability of gluten,increase the solubility of gluten,and improve the dynamic viscosity of gluten dough by changing the content of disulfide bond in gluten.This study hopes to not only improve the functional characteristics of gluten protein,but also provide the basis for future development and improvement of VC-enriched health foods. | Feng Jia Kaichang Ye Changfu Zhang Shihao Zhang Mingxin Fu Xiao Liu Ruijia Guo Ruiting Yang Huiru Zhang Jinshui Wang | 2022 | Grain & Oil Science and Technology2022,5,2: | 0 |
| 18 | The TaTCP4/10-B1 cascade regulates awn elongation in wheat(Triticum aestivum L.)显示文摘Awns are important morphological markers for wheat and exert a strong physiological effect on wheat yield.The awn elongation suppressor B1 has recently been cloned through association and linkage analysis in wheat.However,the mechanism of awn inhibition centered around B1 remains to be clarified.Here,we identified an allelic variant in the coding region of B1 through analysis of re-sequencing data;this variant causes an amino acid substitution and premature termination,resulting in a long-awn phenotype.Transcriptome analysis indicated that B1 inhibited awn elongation by impeding cytokinin-and auxinpromoted cell division.Moreover,B1 directly repressed the expression of TaRAE2 and TaLks2,whose orthologs have been reported to promote awn development in rice or barley.More importantly,we found that TaTCP4 and TaTCP10 synergistically inhibited the expression of B1,and a G-to-A mutation in the B1 promoter attenuated its inhibition by TaTCP4/10.Taken together,our results reveal novel mechanisms of awn development and provide genetic resources for trait improvement in wheat. | Wensheng Ke Jiewen Xing Zhaoyan Chen Yidi Zhao Weiya Xu Lulu Tian Jinquan Guo Xiaoming Xie Dejie Du Zihao Wang Yufeng Li Jin Xu Mingming Xin Weilong Guo Zhaorong Hu Zhenqi Su Jie Liu Huiru Peng Yingyin Yao Qixin Sun Zhongfu Ni | 2023 | Plant Communications2023,4,4: | 0 |
| 19 | PIFs interact with SWI2/SNF2-related 1 complex subunit 6 to regulate H2A.Z deposition and photomorphogenesis in Arabidopsis显示文摘Light is an essential environmental signal perceived by a broad range of photoreceptors in plants. Among them, the red/far-red light receptor phytochromes function to promote photomorphogenesis, which is critical to the survival of seedlings after seeds germination. The basic-helix-loop-helix transcription factors phytochrome-interacting factors (PIFs) are the pivotal direct downstream components of phytochromes. H2A.Z is a highly conserved histone variant regulating gene transcription, and its incorporation into nucleosomes is catalyzed by SWI2/SNF2-related 1 complex, in which SWI2/SNF2-related 1 complex subunit 6 (SWC6) and actin-related protein 6 (ARP6) serve as core subunits. Here, we show that PIFs physically interact with SWC6 in vitro and in vivo, leading to the disassociation of HY5 from SWC6. SWC6 and ARP6 regulate hypocotyl elongation partly through PIFs in red light. PIFs and SWC6 coregulate the expression of auxin-responsive genes such as IAA6, IAA19, IAA20, and IAA29 and repress H2A.Z deposition at IAA6 and IAA19 in red light. Based on previous studies and our findings, we propose that PIFs inhibit photomorphogenesis, at least in part, through repression of H2A.Z deposition at auxin-responsive genes mediated by the interactions of PIFs with SWC6 and promotion of their expression in red light. | Huiru Chen Wanting Wang Xiao Chen Yake Niu Yuanyuan Qi Ze Yu Minyu Xiong Pengbo Xu Wenxiu Wang Tongtong Guo Hong-Quan Yang Zhilei Mao | 2023 | Journal of Genetics and Genomics2023,50,12: | 0 |
