Our forward genetics approach on dark-grown hypocotyls uncovered that an imbalance in membrane lipids enhances the protein abundance of PIN-LIKES (PILS) [E. Barbez et al., Nature 485, 119 (2012)] auxin transport facilitators at the endoplasmic reticulum (ER), which thereby limits nuclear auxin...
The phytohormone auxin influences virtually all aspects of plant growth and development. Auxin transport across membranes is facilitated by, among other proteins, members of the PIN-FORMED (PIN) and the structurally similar PIN-LIKES (PILS) families, which together govern directional cell-to-cell tra...
We performed a forward genetic screen for imperial pils (imp) mutants that enhance the overexpression phenotypes of PIN-LIKES (PILS) putative intracellular auxin transport facilitator. Here we report that the imp1 mutant is defective in the brassinosteroid-receptor BRI1. Our data reveals that BR ...
This mechanism allows PILS proteins to integrate environmental input with phytohormone auxin signaling, contributing to stress-induced growth adaptation in plants. 展开 关键词: auxin endoplasmic reticulum PIN-LIKES protein turnover membrane lipids
growthAuxin and brassinosteroids (BR) are crucial growth regulators and display overlapping functions during plant development. Here, we reveal an alternative phytohormone crosstalk mechanism, revealing that BR signaling controls PIN-LIKES (PILS)-dependent nuclear abundance of auxin. We performed a forward...
PILS(PIN-LIKES)是一类新发现的生长素输出载体,协助生长素的极性运输.本研究立足甘蔗割手密基因组和栽培品种转录组数据,利用生物信息学分析技术,分别在割手密和栽培品种中鉴定到11个PILS(Saccharum spontaneum PIN-LIKES,SsPILS)基因和4个PILS(Saccharum spp.hybrid PIN-LIKES,ScPILS)基因.结果表明,11个SsPILS基因家族...
To study the molecular mechanism of SE, the members of the ABC family, PIN/PILS family, and AUX/LAX family were predicted for the first time in Lilium pumilum. The members of the ABCB subfamily, PIN/PILS family and AUX/LAX family, which participate in polar auxin transport were identified...
