| 11 | The Ghd7 transcription factor represses ARE1 expression to enhance nitrogen utilization and grain yield in rice显示文摘The genetic improvement of nitrogen use efficiency(NUE)of crops is vital for grain productivity and sustainable agriculture.However,the regulatory mechanism of NUE remains largely elusive.Here,we report that the rice Grain number,plant height,and heading date7(Ghd7)gene genetically acts upstream of ABC1 REPRESSOR1(ARE1),a negative regulator of NUE,to positively regulate nitrogen utilization.As a transcriptional repressor,Ghd7 directly binds to two Evening Element-like motifs in the promoter and intron 1 of ARE1,likely in a cooperative manner,to repress its expression.Ghd7 and ARE1 display diurnal expression patterns in an inverse oscillation manner,mirroring a regulatory scheme based on these two loci.Analysis of a panel of 2656 rice varieties suggests that the elite alleles of Ghd7 and ARE1 have undergone diversifying selection during breeding.Moreover,the allelic distribution of Ghd7 and ARE1 is associated with the soil nitrogen deposition rate in East Asia and South Asia.Remarkably,the combination of the Ghd7 and ARE1 elite alleles substantially improves NUE and yield performance under nitrogen-limiting conditions.Collectively,these results define a Ghd7–ARE1-based regulatory mechanism of nitrogen utilization,providing useful targets for genetic improvement of rice NUE. | Qing Wang Qingmei Su Jinqiang Nian Jian Zhang Meng Guo Guojun Dong Jiang Hu Rongsheng Wang Changshuo Wei Guanwen Li Wan Wang Hui-Shan Guo Shaoyang Lin Wenfeng Qian XianzhiXie Qian Qian Fan Chen Jianru Zuo | 2021 | Molecular Plant2021,14,6: | 10 |

| 13 | The Arabidopsis Spontaneous Cell Death1 gene, encoding a ζ-carotene desaturase essential for carotenoid biosynthesis, is involved in chloroplast development, photoprotection and retrograde signalling显示文摘Carotenoids, a class of natural pigments found in all photosynthetic organisms, are involved in a variety of physiologi-cal processes, including coloration, photoprotection, biosynthesis of abscisic acid (ABA) and chloroplast biogenesis.Although carotenoid biosynthesis has been well studied biochemically, the genetic basis of the pathway is not wellunderstood. Here, we report the characterization of two allelic Arabidopsis mutants, spontaneous cell death 1-1 (spcl-1)and spcl-2. The weak allele spcl-1 mutant showed characteristics of bleached leaves, accumulation of superoxide andmosaic cell death. The strong mutant allele spcl-2 caused a complete arrest of plant growth and development shortlyafter germination, leading to a seedling-lethal phenotype. Genetic and molecular analyses indicated that SPC1 encodesa putative ζ-carotene desaturase (ZDS) in the carotenoid biosynthesis pathway. Analysis of carotenoids revealed thatseveral major carotenoid compounds downstream of SPC1/ZDS were substantially reduced in spcl-1, suggesting thatSPC1 is a functional ZDS. Consistent with the downregulated expression of CAO and PORB, the chlorophyll contentwas decreased in spcl-1 plants. In addition, expression of Lhcb1.1, Lhcb1.4 and RbcS was absent in spcl-2, suggestingthe possible involvement of carotenoids in the plastid-to-nucleus retrograde signaling. The spcl-1 mutant also displaysan ABA-deficient phenotype that can be partially rescued by the externally supplied phytohormone. These results suggestthat SPC1/ZDS is essential for biosynthesis of carotenoids and plays a crucial role in plant growth and development. | Haili Dong Yan Deng Jinye Mu Qingtao Lu Yiqin Wang Yunyuan Xu Chengcai Chu Kang Chong Congming Lu Jianru Zuo | 2007 | Cell Research2007,17,5: | 8 |

| 15 | Characterization of a new mutant allele of the Arabidopsis Flowering Locus D (FLD) gene that controls theflowering time by repressing FLC显示文摘Flowering in higher plants is controlled by both the internal and environmental cues. In Arabidopsis, several major genetic loci have been defined as the key switches to control flowering. The Flowering Locus C (FLC) gene has been shown in the autonomous pathway to inhibit the vege-tative-to-reproductive transition. FLC appears to be re-pressed by Flowering Locus D (FLD), which encodes a com-ponent of the histone deacetylase complex. Here we report the identification and characterization of a new mutant allele fld-5. Genetic analysis indicates that fld-5 (in the Was-silewskija background) is allelic to the previously character-ized fld-3 and fld-4 (in the Colombia-0 background). Genetic and molecular analyses reveal that fld-5 carries a frame-shift mutation, resulting in a premature termination of the FLD open reading frame. The FLC expression is remarkably in-creased in fld-5, which presumably attributes to the ex-tremely delayed flowering phenotype of the mutant. | CHEN Ruiqiang ZHANG Suzhi SUN Shulan CHANG Jianhong ZUO Jianru | 2005 | Chinese Science Bulletin2005,50,23: | 6 |

| 17 | Regulation of mitochondrial NAD pool via NAD^+ transporter 2 is essential for matrix NADH homeostasis and ROS production in Arabidopsis显示文摘Reactive oxygen species(ROS) play a crucial role in numerous biological processes in plants, including development, responses to environmental stimuli, and programmed cell death(PCD). Deficiency in MOSAIC DEATH 1(MOD1), a plastid-localized enoyl-ACP reductase essential for de novo fatty acid biosynthesis in Arabidopsis thaliana, leads to the increased malate export from chloroplasts to mitochondria, and the subsequent accumulation of mitochondria-generated ROS and PCD. In this study, we report the identification and characterization of a mod1 suppressor, som592. SOM592 encodes mitochondrion-localized NAD^+ transporter 2(NDT2). We show that the mitochondrial NAD pool is elevated in the mod1 mutant. The som592 mutation fully suppressed mitochondrial NADH hyper-accumulation, ROS production, and PCD in the mod1 mutant, indicating a causal relationship between mitochondrial NAD accumulation and ROS/PCD phenotypes. We also show that in wild-type plants, the mitochondrial NAD+uptake is involved in the regulation of ROS production in response to continuous photoperiod. Elevation of the alternative respiration pathway can suppress ROS accumulation and PCD in mod1, but leads to growth restriction. These findings uncover a regulatory mechanism for mitochondrial ROS production via NADH homeostasis in Arabidopsis thaliana that is likely important for growth regulation in response to altered photoperiod. | Lilan Luo Yajun He Yannan Zhao Qian Xu Jian Wu Haiyan Ma Hongyan Guo Lin Bai Jianru Zuo Jian-Min Zhou Hong Yu Jiayang Li | 2019 | Science China(Life Sciences)2019,62,8: | 5 |
| 18 | LATERAL ROOTLESS2, a Cyclophilin Protein, Regulates Lateral Root Initiation and Auxin Signaling Pathway in Rice显示文摘Dear Editor, Cyclophilins (CYP) are a class of highly conserved peptidyl-prolyl cis-trans isomerases (PPlases) that play important roles in various biological processes in eukaryotes (reviewed in Romano et al.(2004)).In higher plants,a conserved single domain cyclophilin has been identified as a novel component of the auxin signaling pathway by analyzing the tomato diageotropica (dgt) mutant (Ivanchenko et al.,2006;Oh et al.,2006).The dgt mutant displays a lateral-rootless and auxin-resistant phenotype (Ivanchenko et al.,2006).Further studies revealed that mutations in the DGT-like genes of Physcomitrella patens also exhibited an auxin-resistant phenotype,suggesting a conserved role of DGT-like proteins in auxin signaling.Moreover,mutation in PpDGT gene suppresses the auxin hypersensitive phenotype conferred by the overexpression of the auxin receptor gene PpAFB2,indicating that PpDGT acts downstream of PpAFB2 (Lavy et al.,2012). | Huakun Zheng Suiuan Li Bo Ren Jian Zhang Masahiko Ichii Shin Taketa Yuezhi Tao Jianru Zuo Hua Wang | 2013 | Molecular Plant2013,6,5: | 4 |
| 19 | The Arabidopsis CROWDED NUCLEI genes regulate seed germination by modulating degradation of ABI5 protein显示文摘In Arabidopsis, the phytohormone abscisic acid(ABA)plays a vital role in inhibiting seed germination and in postgermination seedling establishment. In the ABA signaling pathway, ABI5, a basic Leu zipper transcription factor, has important functions in the regulation of seed germination. ABI5 protein localizes in nuclear bodies, along with AFP, COP1, and SIZ1,and was degraded through the 26 S proteasome pathway.However, the mechanisms of ABI5 nuclear body formation and ABI5 protein degradation remain obscure. In this study, we found that the Arabidopsis CROWDED NUCLEI(CRWN) proteins,predicted nuclear matrix proteins essential for maintenance of nuclear morphology, also participate in ABA-controlled seed germination by regulating the degradation of ABI5 protein. During seed germination, the crwn mutants are hypersensitive to ABA and have higher levels of ABI5 protein compared to wild type.Genetic analysis suggested that CRWNs act upstream of ABI5. The observation that CRWN3 colocalizes with ABI5 in nuclear bodiesindicates that CRWNs might participate in ABI5 protein degrada tion in nuclear bodies. Moreover, we revealed that the extreme C-terminal of CRWN3 protein is necessary for its function in the response to ABA in germination. Our results suggested importan roles of CRWNs in ABI5 nuclear body organization and ABI5 protein degradation during seed germination. | Wenming Zhao Chunmei Guan Jian Feng Yan Liang Ni Zhan Jianru Zuo Bo Ren | 2016 | Journal of Integrative Plant Biology2016,58,7: | 3 |
