柳暗花明:胞外生长素信号感受的新突破
There Is a Way Out-new Breakthroughs in Extracellular Auxin Sensing
摘要
Abstract
Auxin plays an important role in plant growth and development and its signal transduction has always been the focus of attention in the field of plant biology.AUXIN BINDING PROTEIN 1(ABP1)-TRANSMEMBRANE KINASE(TMK)molecular module is involved in the extracellular auxin perception.In recent years,ABP1 has been controversial as an auxin receptor.Recently,Tongda Xu's team and Zhenbiao Yang's team from Fujian Agriculture and Forestry University identified ABP1-LIKE PROTEIN(ABL)as the auxin binding proteins involved in the extracellular auxin perception.Dif-ferent from traditional functional redundancy,ABL and ABP1 achieve functional compensation effect through protein structure similarity,and then form complex with TMK at the plasma membrane,acting as co-receptors of apoplastic auxin to mediate auxin driven rapid response.This study deeply dissects the mechanism of extracellular auxin sensing,which is a breakthrough in the field of auxin signaling transduction.关键词
