| 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 |
| 2 | 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 |
| 3 | 多因素调控作物促分蘖机理研究进展显示文摘禾本科(Gramineae)植物中水稻(Oryzasativa L.)、小麦(Triticum aestivum L.)等都是重要的粮食作物,其产量对于人类来说有重要意义.提高粮食产量以满足人类对粮食质量和数量不断增长的需求至关重要,水稻、小麦等禾本科植物主要通过分蘖来提高产量.分蘖的生长发育受多方面因素影响,为了提高作物产量,前人对分蘖的发生和调控做了不少研究.本文主要综述了氮元素对分蘖的影响,多种植物激素对分蘖的作用,与分蘖有关的基因对分蘖的调控机制,禾草内生真菌与宿主植物共生对分蘖的促进作用,最后还评述了温度、水分、播期和密度对分蘖的影响.对禾本科内生真菌促分蘖的内源激素研究方向提出了展望. | 韩丹 米璟钰 李晓霞 陈水红 | 2021 | 渤海大学学报(自然科学版)2021，42，4： | 2 |
| 4 | 独脚金内酯与激素互作调控根系生长的研究进展显示文摘独脚金内酯是调控植物根系生长的新型植物激素,在刺激寄生植物种子萌发、促进丛枝菌根真菌菌丝分枝以及调节植物分枝等过程中发挥着重要的作用。根系是植物感知土壤信号以及吸收养分、水分和矿质元素等的重要器官。外部环境和内部激素均能影响植物根系的生长发育。独脚金内酯可以抑制生长素转运而增加分生区及过渡区大小调控主根伸长、抑制侧根原基的发生和侧根发育,该过程同时依赖于细胞分裂素受体AHK3,也可以促进乙烯的合成和生长素转运及其受体TIR1的表达而调控根毛伸长。综述了独脚金内酯的结构、功能及其与生长素和细胞分裂素等植物激素互作调控主根伸长、侧根发生、根毛的发生和伸长等过程,以期为阐明独脚金内酯调控植物根系生长的机制提供理论与实践依据。 | 沈月 陶宝杰 华夏 吕冰 刘立军 陈云 | 2022 | 生物技术通报2022，38，8： | 1 |

| 7 | Current perspectives on shoot branching regulation显示文摘Shoot branching is regulated by the complex interactions among hormones, development, and environmental factors. Recent studies into the regulatory mechanisms of shoot branching have focused on strigolactones,which is a new area of investigation in shoot branching regulation. Elucidation of the function of the D53 gene has allowed exploration of detailed mechanisms of action of strigolactones in regulating shoot branching. In addition,the recent discovery that sucrose is key for axillary bud release has challenged the established auxin theory, in which auxin is the principal agent in the control of apical dominance. These developments increase our understanding of branching control and indicate that regulation of shoot branching involves a complex network. Here, we first summarize advances in the systematic regulatory network of plant shoot branching based on current information. Then we describe recent developments in the synthesis and signal transduction of strigolactones.Based on these considerations, we further summarize the plant shoot branching regulatory network, including long distance systemic signals and local gene activity mediated by strigolactones following perception of external environmental signals, such as shading, in order to provide a comprehensive overview of plant shoot branching. | Cunquan YUAN Lin XI Yaping KOU Yu ZHAO Liangjun ZHAO | 2015 | Frontiers of Agricultural Science and Engineering2015，2，1： | 0 |
