| 1 | Vacuole Integrity Maintained by DUF300 Proteins Is Required for Brassinosteroid Signaling Regulation显示文摘Brassinosteroid (BR ) 荷尔蒙发信号在植物生长和开发期间控制多重进程并且和象联系 BRI1 的受体 KINASE1 (BAK1 ) 那样的合作受体通过受体 kinase BRASSINOSTEROID INSENSITIVE1 (BRI1 ) 在血浆膜被开始。BRI1 丰富被 endosomal 再循环并且 vacuolar 指向调整,但是在 BR 受体动力学和 BR 回答的液泡相关的蛋白质的角色留下逃犯。这里,我们证明 BR 发信号的二 DUF300 包含域的 tonoplast 蛋白质, LAZARUS1 (LAZ1 ) 和 LAZ1 HOMOLOG1 (LAZ1H1 ) 的缺席,原因液泡形态学缺点,生长抑制,和组成的激活。有趣地, BAK1 的 tonoplast 累积实质地被增加并且显得有原因地在 laz1 laz1h1 植物连接了到提高的 BRI1 trafficking 和降级。因为无关的液泡异种展出了正常 BR 回答,我们的调查结果显示 DUF300 蛋白质在由维持要求平衡 subcellular BAK1 水池和 BR 受体分发的液泡正直发信号的 BR 的规定起不同作用。 | Qinsong Liu Thomas Vain Corrado Viotti Siamsa M, Doyle Danuse Tarkowska Ondrej Novak Cyril Zipfel Folke Sitbon Stephanie Robert Daniel Hofius | 2018 | Molecular Plant2018，11，4： | 2 |
| 2 | The HB40-JUB1 transcriptional regulatory network controls gibberellin homeostasis in Arabidopsis显示文摘The gibberellins(GAs)are phytohormones that play fundamental roles in almost every aspect of plant growth and development.Although GA biosynthetic and signaling pathways are well understood,the mechanisms that control GA homeostasis remain largely unclear in plants.Here,we demonstrate that the homeobox transcription factor(TF)HB40 of the HD-Zip family regulates GA content at two additive con-trol levels in Arabidopsis thaliana.We show that HB40 expression is induced by GA and in turn reduces the levels of endogenous bioactive GAs by simultaneously reducing GA biosynthesis and increasing GA deac-tivation.Consistently,HB40 overexpression leads to typical GA-deficiency traits,such as small rosettes,reduced plant height,delayed flowering,and male sterility.By contrast,a loss-of-function hb40 mutation enhances GA-controlled growth.Genome-wide RNA sequencing combined with molecular-genetic ana-lyses revealed that HB40 directly activates the transcription of JUNGBRUNNEN1(JJUB1),a key TF that re-presses growth by suppressing GA biosynthesis and signaling.HB40 also activates genes encoding GA 2-oxidases(GA2oxs),which are major GA-catabolic enzymes.The effect of HB40 on plant growth is ultimately mediated through the induction of nuclear growth-repressing DELLA proteins.Collectively,our results reveal the important role of the HB40-JUB1 regulatory network in controlling GA homeostasis during plant growth. | Shuchao Dong Danuse Tarkowska Mastoureh Sedaghatmehr Maryna Welsch Saurabh Gupta Bernd Mueller-Roeber Salma Balazadeh | 2022 | Molecular Plant2022，15，2： | 0 |
