| 1 | Strigolactones and Brassinosteroids Antagonistically Regulate the Stability of the D53-OsBZR1 Complex to Determine FC1 Expression in Rice Tillering显示文摘Rice tillering,a key architecture trait determ ining grain yield,is highly regulated by a class of newly identified phytohorm ones,strigolactones(SLs).How ever,the whole SL signaling pathw ay from the receptor to dow nstream transcription factors to finally inhibit tillering remains unrevealed.In this study,we first found that brassinosteroids(BRs)strongly enhance tillering by prom oting bud outgrow th in rice,which is largely different from the function of BRs in Arabidopsis.Genetic and biochem ical analyses indicated that both the SL and BR signaling pathw ays control rice tillering by regulating the stability of D53 and/or the OsBZR1 RLA1-DLT module,a transcriptional complex in the rice BR signaling pathway.We further found that D53 interacts with OsBZR1 to inhibit the expression of FC1,a local inhibitor of tillering,and that this inhibition depends on direct DNA binding by OsBZR1,which recruits D53 to the FC1 promoter in rice buds.Taken together,these findings uncover a mechanism illustrating how SLs and BRs coordinately regulate rice tillering via the early responsive gene FC1. | Zhongming Fang Yuanyuan Ji Jie Hu Renkang Guo Shiyong Sun Xuelu Wang | 2020 | Molecular Plant2020，13，4： | 20 |

| 5 | BES1 Functions as the Co-regulator of D53-like SMXLs to Inhibit BRC1 Expression in Strigolactone-Regulated Shoot Branching in Arabidopsis显示文摘Shoot branching,determining plant architecture and crop yield,is critically controlled by strigolactones(SLs).However,how SLs inhibit shoot branching after its perception by the receptor complex remains largely obscure.In this study,using the transcriptomic and genetic analyss as well as biochemical studies,we reveal the key role of BES1 in the SL-regulated shoot branching.Wedemonstrate that BES1 and D53-like SMXLs,the substrates of SL receptor complex D14–MAX2,interact with each other to inhibit BRC1 expression,which specifically triggers the SL-regulated transcriptional network in shoot branching.BES1 directly binds the BRC1 promoter and recruits SMXLs to inhibit BRC1 expression.Interestingly,despite being the shared component by SL and brassinosteroid(BR)signaling,BES1 gains signal specificity through different mechanisms in response to BR and SL signals. | Jie Hu Yuanyuan Ji Xiaotong Hu Shiyong Sun Xuelu Wang | 2020 | Plant Communications2020，1，3： | 9 |
| 6 | PdAg bimetallic electrocatalyst for highly selective reduction of CO2 with low COOH^* formation energy and facile CO desorption显示文摘For electrocatalytic reduction of CO2 to CO,the stabilization of intermediate COOH^* and the desorption of CO^* are two key steps.Pd can easily stabilize COOH^*,whereas the strong CO^* binding to Pd surface results in severe poisoning,thus lowering catalytic activity and stability for CO2 reduction.On Ag surface,CO^* desorbs readily,while COOH^* requires a relatively high formation energy,leading to a high overpotential.In light of the above issues,we successfully designed the PdAg bimetallic catalyst to circumvent the drawbacks of sole Pd and Ag.The PdAg catalyst with Ag-terminated surface not only shows a much lower overpotential(-0.55 V with CO current density of 1 mA/cm^2)than Ag(−0.76 V),but also delivers a CO/H2 ratio 18 times as high as that for Pd at the potential of-0.75 V vs.RHE.The issue of CO poisoning is significantly alleviated on Ag-terminated PdAg surface,with the stability well retained after 4h electrolysis at-0.75 V vs.RHE.Density functional theory(DFT)calculations reveal that the Ag-terminated PdAg surface features a lowered formation energy for COOH^* and weakened adsorption for CO^*,which both contribute to the enhanced performance for CO2 reduction. | Rui Lin Xuelu Ma Weng-Chon Cheong Chao Zhang Wei Zhu Jiajing Pei Kaiyue Zhang Bin Wang Shiyou Liang Yuxi Liu Zhongbin Zhuang Rong Yu Hai Xiao Jun Li Dingsheng Wang Qing Peng Chen Chen Yadong Li | 2019 | Nano Research2019，12，11： | 7 |

| 8 | The Intrinsically Disordered Protein BKI1 Is Essential for Inhibiting BRI1 Signaling in Plants显示文摘Dear Editor, Brassinosteroids (BRs) are a class of essential polyhydroxylated steroid hormones regulating plant growth and development,and their responses to environmental cues (Clouse,2011;Yang et al.,2011).BRs are perceived at the plasma membrane by a receptor complex,which consists of two leucine-rich receptor-like kinases (LRR-RLKs),BRASSINOSTEROID INSENSITIVE 1 (BRI1) and BRI1-ASSOCIATED RECEPTOR KINASE 1 (BAK1).When activated by BRs,the receptor complex initiates a cascade of multiple kinases and phosphatases,ultimately leading to the dephosphorylation and activation of a family of closely related transcription factors,including BRI1-EMS SUPPRESSOR1 (BES1) and BRASSINAZOLE-RESISTANT1 (BZR1),to regulate the expression of thousands of target genes (Guo et al.,2013). | Jianjun Jiang Tao Wang Zhihua Wu Jie Wang Chi Zhang Haijiao Wang Zhi-Xin Wang Xuelu Wang | 2015 | Molecular Plant2015，8，11： | 7 |
| 9 | Ligand Perception,Activation,and Early Signaling of Plant Steroid Receptor Brassinosteroid Insensitive 1显示文摘Leucine-rich repeat receptor-like kinases(LRR-RLKs)belong to a large group of cell surface proteins involved in many aspects of plant development and environmental responses in both monocots and dicots.Brassinosteroid insensitive 1(BRI1),a member of the LRR X subfamily,was frst identifed through several forward genetic screenings for mutants insensitive to brassinosteroids(BRs),which are a class of plant-specifc steroid hormones.Since its identifcation,BRI1 and its homologs had been proved as receptors perceiving BRs and initiating BR signaling.The co-receptor BRI1-associated kinase 1and its homologs,and other BRI1 interacting proteins such as its inhibitor BRI1 kinase inhibitor 1(BKI1)were identifed by genetic and biochemical approaches.The detailed mechanisms of BR perception by BRI1 and the activation of BRI1receptor complex have also been elucidated.Moreover,several mechanisms for termination of the activated BRI1 signaling were also discovered.In this review,we will focus on the recent advances on the mechanism of BRI1 phosphorylation and activation,the regulation of its receptor complex,the structure basis of BRI1ectodomain and BR recognition,its direct substrates,and the termination of the activated BRI1 receptor complex. | Jianjun JiangWang Chi ZhangWang Xuelu Wang | 2013 | Journal of Integrative Plant Biology2013，55，12： | 6 |
| 10 | Regulation of Shoot Branching by Strigolactones and Brassinosteroids: Conserved and Specific Functions of Arabidopsis BES1 and Rice BZR1显示文摘Shoot branching results from axillary bud initiation and bud outgrowth and determines plant architecture and productivity.Strigolactones(SLs)are a class of terpenoid phytohormones that were identified to inhibit bud outgrowth in 2008.The core SL signaling pathway has been established in the last decade.Following the identification of the α/β hydrolase DWARF14(D14)as a putative SL receptor,independent studies have proposed a variety of models explaining how SLs are perceived and D14 is activated(reviewed in detail by Burger and Chory,2020).SLs bind to D14 and are hydrolyzed into their active form,which activates D14 and facilitates its interaction with the F-box protein DWARF 3(D3)in rice,or its Arabidopsis ortholog MORE AXILLARY GROWTH2(MAX2)(Burger and Chory,2020).The F-box protein then recruits and ubiquitinates downstream substrates. | Jie Hu Shiyong Sun Xuelu Wang | 2020 | Molecular Plant2020，13，6： | 5 |
| 11 | Effects of capture and captivity on plasma corticosterone and metabolite levels in breeding Eurasian Tree Sparrows显示文摘Background: Bringing free-living animals into captivity subjects them to the stress of both capture and captivity, leading to the alteration of normal physiological processes and behaviors through activation of the hypothalamic– pituitary–adrenal axis. In free-living birds, although elevated plasma corticosterone (CORT) is an important adaptation regulating physiological and behavioral responses during the process of capture and captivity stress, little information is currently available on the effects of such stress on plasma metabolite levels. Methods: We examined the effects of immediate capture and 24-h captivity on body mass, body condition, plasma CORT, and metabolite levels including glucose (Glu), triglyceride (TG), total cholesterol (TC), uric acid (UA), in breeding Eurasian Tree Sparrows (Passer montanus). Results: CORT and Glu levels were increased significantly by the stress of capture, whereas TC and UA levels decreased. Body mass, body condition declined notably after 24 h in captivity, but CORT, Glu, and UA levels increased. Furthermore, male sparrows had lower TG levels after both capture and captivity than those of females. The relationships between plasma CORT and metabolite levels varied between sexes. Conclusions: Our results revealed that the metabolic status of Eurasian Tree Sparrows could be dramatically altered by capture and captivity. Monitoring the dynamic effects of both capture and captivity on plasma CORT, metabolite levels in a free-living bird contributes to a better understanding of the stress-induced pathways involved in sexdependent energy mobilization. | Mo Li Weiwei Zhu Yang Wang Yanfeng Sun Juyong Li Xuelu Liu Yuefeng Wu Xuebin Gao Dongming Li | 2019 | Avian Research2019，10，2： | 5 |

| 13 | GSK3-mediated stress signaling inhibits legume-rhizobium symbiosis by phosphorylating GmNSP1 in soybean显示文摘Legumes establish symbiotic associations with rhizobia for biological nitrogen fixation.This process is highly regulated by various abiotic stresses,but the underlying genetic and molecular mechanisms remain largely unknown.In this study,we discovered that the glycogen synthase kinase 3(GSK3)-like kinase,GmSK2-8,plays an important role in inhibiting symbiotic signaling and nodule formation in soybean(Glycine max)under salt stress.We found that GmSK2-8 is strongly induced in soybean under high-salt conditions,while GmSK2-8 could interact with two G.max Nodulation Signaling Pathway 1(GmNSP1)proteins,GmNSP1a and GmNSP1b;these key transcription factors are essential for rhizobial infection,nodule initiation,and symbiotic gene expression in soybean.Furthermore,we demonstrated that GmSK2-8 phosphorylates the LHRI domain of GmNSP1a,inhibits its binding to the promoters of symbiotic genes,and thus suppresses nodule formation under salt stress.Knockdown of GmSK2-8 and its close homologs also resulted in reduced plant sensitivity to salt stress during nodule formation.Taken together,our findings indicate that GSK3-like kinases directly regulate the activities of GmNSP1s to mediate salt-inhibited legume–rhizobium symbiosis,providing novel targets for improving symbiotic nitrogen fixation under environmental stress conditions in soybean and possibly other legumes. | Chunmei He Hui Gao Haijiao Wang Yun Guo Miao He Yaqi Peng Xuelu Wang | 2021 | Molecular Plant2021，14，3： | 5 |

| 17 | A comprehensive understanding of the anionic redox chemistry in layered oxide cathodes for sodium-ion batteries显示文摘Sodium-ion batteries(SIBs) have demonstrated great application prospects in large-scale energy storage systems and low-speed electric vehicles due to the cost effectiveness and abundant resources. Layered transition-metal oxides are recognized as one of the most attractive sodium-ion storage cathode candidates by virtue of their high compositional diversity, environmental friendliness, ease of synthesis, and promising theoretical capacities. The practicability, however, is still limited by the fact that the energy densities of most Na-storage layered oxide cathodes solely using the conventional cationic redox are not comparable to those of the lithium-ion storage counterparts. Recently, the strategy of activating anionic redox(O^(2-)/O^(n-)) which is popular in Li-rich layered materials has been successfully applied in oxide cathodes of SIBs to promote the energy density to a new level. It is interesting to note that excess Na is not the prerequisite to induce anionic redox in sodium oxides, indicating a new mechanism underlying Na-ion materials. Herein, the latest advances on the anionic redox chemistry in layered oxide cathodes for SIBs,including the fundamental theories, triggering strategies, and applicable cathode materials, are comprehensively reviewed.Moreover, the challenges(mainly O_(2) release) facing anionic redox are discussed, and the possible remedies are outlined for future developments toward a highly reversible oxygen usage. We believe that this review can provide a valuable guidance for the exploration of high-energy layered oxide cathode materials of SIBs. | Junteng Jin Yongchang Liu Xuelu Pang Yao Wang Xianran Xing Jun Chen | 2021 | Science China Chemistry2021，64，3： | 3 |
| 18 | The Strigolactone-Related Mutants have Enhanced Lamina Joint Inclination Phenotype at the Seedling Stage显示文摘Strigolactones(SLs)are a class of newly discovered plant hormones and play diverse roles in plant growth and development.Recently,it has been demonstrated that SLs negatively regulate shoot branching by inhibiting bud outgrowth in plants(Umehara et al.,2008).Several genes involved in SL biosynthesis or signaling had been identified in both monocots and dicots.Loss-of-function mutants corresponding to these genes exhibit enhanced shoot branching phenotype(Beveridge and Kyozuka,2010).In rice,the SL biosynthetic mutants,d17/htd1 and d10,are caused by mutation of carotenoid cleavage dioxygenase 7(CCD7)and carotenoid cleavage dioxygenase 8(CCD8),respectively(Zou et al.,2006;Arite et al,2007).The SL biosynthetic mutant,d27,is caused by a mutation of | Xiaoming Li Shiyong Sun Chengxiang Li Shenglong Qiao Tao Wang Linna Leng Hongyun Shen Xuelu Wang | 2014 | Journal of Genetics and Genomics2014，41，11： | 3 |
| 19 | Petrogenesis of Early Carboniferous Ultramafic-Mafic Volcanic Rocks in the Southern Changning-Menglian Belt,Southeastern Tibetan Plateau:Implications for the Evolution of the Paleo-Tethyan Ocean显示文摘The Changning-Menglian Belt represents the main Paleo-Tethyan Suture in the southeastern Tibetan Plateau,which divides Gondwana-and Eurasia-derived continental fragments from each other.The belt contains ultramafic-mafic volcanic rocks that provide evidence of the tectonic processes which operated during the evolution of the Paleo-Tethyan Ocean.New geochemical data for Early Carboniferous volcanics in the southern Changning-Menglian Belt show that wehrlites have cumulate and poikilitic textures,and contain low-Fo(84.2-87.2)olivine,clinopyroxene with low Mg#values(79.4-85.6),and spinel with high Cr#values(67.8-72.4).Estimated equilibrium temperatures obtained using olivine-spinel Fe-Mg exchange geothermometry range from 978℃ to 1373℃(mean=1205℃;n=3).These observations combined with a lack of reaction or melt impregnation textures indicate that these units represent magmatic cumulates rather than having formed as a result of mantle-melt reactions.Both wehrlites and basalts in the belt have subparallel rare earth element(REE)-and primitive-mantle-normalized multi-element patterns with slightly positive Nb-Ta anomalies,but negligible Eu and Zr-Hf anomalies.The volcanics have similar Sr-Nd-Pb isotopic compositions withεNd(t)values of 4.2-4.5(mean=4.3;n=3)and 4.0-4.4(mean 4.2;n=4),respectively,and also have similar immobile element ratios,such as Nb/La,Nb/U,Th/La,Zr/Nb,Th/Ta,La/Yb,Nb/Th,Nb/Y,and Zr/Y.These characteristics indicate both units have ocean island basalt(OIB)-like geochemical affinities,consistent with the fact that the clinopyroxene in the wehrlites is compositionally similar to OIB-related cumulus clinopyroxene.This suggests that both the wehrlites and basalts were derived from similar parental magmas that underwent generally closed-system magmatic differentiation dominated by fractionation of the olivine and clinopyroxene.This parental magma was likely generated in an oceanic seamount setting from an OIB-type mantle source(i.e.,asthenospheric mantle)containing garnet-spinel lherzolite material.Combing this new data with that from oceanic seamount volcano-sedimentary suites derived from previous research enables the identification of a mature late Paleozoic ocean basin between the passive northeastern Gondwanan margin and the northward-migrating microcontinent of Lanping-Simao. | XIE Zhipeng WU Xuelu WANG Tengfei XUE Chuandong YANG Tiannan WANG Wei SUI Binxi XIN Di | 2022 | Acta Geologica Sinica(English Edition)2022，96，3： | 2 |
| 20 | Surface Passivation and Energetic Modification Suppress Nonradiative Recombination in Perovskite Solar Cells显示文摘Surface passivation via post-treatment is an important strategy for improving power conversion efficiency and operational stability of perovskite solar cells.However,so far the interaction mechanisms between passivating additive and perovskite are not well understood.Here,we report the atomic-scale interaction of surface passivating additive 2,2-difluoroethylammonium bromine(2FEABr)on the MAPbI_(3).It is found that the bulky 2FEA+cations tend to distribute at film surface,while the Br−anions diffuse from surface into bulk.A combination of 19F,207Pb,and 2H solid-state NMR further reveal the Br−anions’partial substitution for the I−sites,the restricted motion of partial MA+cations,and the firmed perovskite lattices,which would improve charge transport and stability of the perovskite films.Optical spectroscopy and ultraviolet photoelectron spectroscopy demonstrate that the 2FEABr induced surface passivation and energetic modification suppress the nonradiative recombination loss.These findings enable the efficiency of the p-i-n structured PSC significantly increasing from 19.44 to 21.06%,accompanied by excellent stability.Our work further establishes more knowledge link between passivating additive and PSC performance. | Wei Dong Wencheng Qiao Shaobing Xiong Jianming Yang Xuelu Wang Liming Ding Yefeng Yao Qinye Bao | 2022 | Nano-Micro Letters2022，14，7： | 2 |
