| 1 | 植物与丛枝菌根真菌在共生早期的信号交流显示文摘丛枝菌根真菌(Arbuscular Mycorrhizal Fungi,AMF)与大多数陆生植物互利共生具有广泛的生理生态学意义,而这一生态学功能背后的共生机制我们知之甚少。已探明AM形成前宿主植物根分泌的独脚金内酯促进AMF菌丝分支,分泌的角质单体促进AMF在宿主根中定植;同时,菌根真菌的分支菌丝释放出脂质几丁糖(lipochitooligosaccharides,LCOs)和短链几丁质寡聚物(short-chain chitin oligomers,COs)信号分子诱导宿主基因表达、侧根发育以及形成Ca2+振荡,它们相互作用共同促进AM形成。在能同时形成菌根和根瘤的蒺藜苜蓿(Medicago truncatula)和日本百脉根(Lotus corniculatus)植物中,根瘤共生体形成过程所需的若干基因与菌根形成所需的基因有关。这些研究成果为全面揭示菌根共生体发生过程的信号转导奠定了基础。本文对目前国内外宿主植物与AM真菌之间的信号物质及其功能、相关基因及其调控功能等进行了综述,旨在为AM真菌共生早期的信号交流研究提供有价值的参考。 | 段倩倩 杨晓红 黄先智 | 2015 | 微生物学报2015，55，7： | 8 |
| 2 | 根内生真菌印度梨形孢侵染对黑麦草气体交换和生长发育的影响显示文摘植物根内生真菌印度梨形孢(Piriformospora indica)具有广泛的侵染能力,可以提高植物的生长发育和抗逆性。通过盆栽试验对黑麦草进行印度梨形孢接种,以研究印度梨形孢对黑麦草气体交换和生长发育的影响。试验结果表明,印度梨形孢对黑麦草的侵染可以显著提高其黑麦草光系统II光量子产量Y(II)和光化学淬灭qP以及净光合速率和气孔导度,而显著降低胞间二氧化碳浓度;同时显著降低黑麦草的水分利用效率,而显著提高其光能利用效率。印度梨形孢与黑麦草共生使黑麦草的总生物量增加了10.87%。 | 吴楚 税蓉 韦巧 张文英 | 2018 | 草地学报2018，26，3： | 6 |
| 3 | Silencing GRAS2 reduces fruit weight in tomato显示文摘GRAS family transcription factors are involved in multiple biological processes in plants.Here, we report that GRAS2 plays a vital role in regulating fruit weight in tomato(Solanum lycopersicum).We establish that the expression of GRAS2 was elevated in ovaries and maintained at a constant level in fertilized ovules.Reduction of GRAS2 expression in transgenic plants reduced fruit weight through modulating ovary growth and cell size.At the metabolic level, downregulation of GRAS2 decreased activities of the gibberellic acid biosynthesis and signal transduction pathways, leading to insufficient levels of active gibberellic acid during the initial ovary development of tomato.Moreover, genotypic diversity of GRAS2 was consistent with the molecular basis of fruit weight evolution, suggesting that GRAS2 contributes to the molecular basis of the evolution of fruit weight in tomato.Collectively, these findings enhance our understanding of GRAS2 functions, in fruit development of tomato, and demonstrate a strong association between the GRAS gene family and fruit development. | Miao Li Xin Wang Changxing Li Hanxia Li Junhong Zhang Zhibiao Ye | 2018 | Journal of Integrative Plant Biology2018，60，6： | 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 |
| 5 | AMF对观赏植物生长发育影响的研究进展显示文摘从植物营养转运、表观形态、光合作用以及非生物胁迫抗性4个方面总结丛枝菌根真菌(AMF)对观赏植物生长发育的影响。分析表明,AMF通过调控营养转运基因的表达和提高观赏植物吸收养分的面积促进观赏植物体内营养元素的积累,改善植物营养吸收;通过提高植物体内叶绿素含量、光合酶活性等提高植物的碳固定能力和改善源-库关系,进而增强植物光合作用效率;通过调控渗透调节物质、抗氧化等酶活性提高植物的抗旱、耐盐碱及高温等抗逆性。今后应进一步研究AMF参与钾离子、叶绿素荧光参数以及胁迫相关转录因子(如GRAS家族、AP2/ERF家族、MYB家族)的调控机制,以探究AMF的共生机制。 | 黄文镜 杨树华 葛红 寇亚平 赵鑫 贾瑞冬 陈己任 | 2023 | 中国农学通报2023，39，7： | 0 |
| 6 | Plant mineral nutrient sensing and signaling显示文摘As terrestrial plants are sessile organisms and therefore must directly deal with an often complex and changing environment,they have had to develop complex and elegant strategies to survive and thrive in the face of environmental stress.This is particularly true for plant adaptation to the soil environment,where essential mineral nutrients often are found at suboptimal levels and their concentrations can vary significantly,both spatially and temporally.Furthermore,plants also at times have to respond to excessively high and potentially toxic levels of essential nutrients,as well as toxic levels of nonessential metals and metalloids in the soil.Although plant mineral nutrition as a bona fide research discipline has a history of over 150 years,beginning with the pioneering work of Justus Von Liebieg and others in the mid‐1800’s,it is only very recently that researchers have begun to truly appreciate how sophisticated plants are with regards to the sensing of their mineral status and the maintaining of mineral homeostasis | Leon V.Kochian William J.Lucas | 2014 | Journal of Integrative Plant Biology2014，56，3： | 0 |
