1On-Off Switches for Secondary Cell Wall Biosynthesis显示文摘第二等的房间墙向植物提供刚硬和力量支持他们的身体重量并且保证水和滋养的运输。他们也为人的使用提供纺织品,木材,和潜在地第二代的 biofuels。为不同房间的合成负责的基因围部件,也就是纤维素, hemicelluloses,和木质素,并列地被表示并且在 transcriptional 下面规定。在过去的几年里,房间墙相关的 NAC 和 MYB 抄写因素强烈地在不同种类被调查了并且出现是第二等的房间墙生合成的主人开关。积极、否定的管理者, NAC 主人在上游的功能交换,也在不同植物纸巾被识别了。房间墙合成的规章的机制的进一步的说明将便于对 biofuel 生产合适的植物化工物品的工程。Huan-Zhong Wang Richard A.Dixon 2012Molecular Plant2012,5,2:20
2Deciphering the Enigma of Lignification: Precursor Transport, Oxidation, and the Topochemistry of Lignin Assembly显示文摘植物木质化是经由三顺序的步发生的一个紧调整的复杂细胞的过程:在 cytosol 以内的 monolignols 的合成;越过血浆膜的 monomeric 先锋的运输;并且到在房间墙以内的形式木质素大分子的 monolignols 的氧化聚合。尽管我们有 monolignol 生合成的合理理解,木质素汇编的许多方面留下逃犯。这些包括先锋运输和氧化,和木质素聚合的开始。这评论描述我们位于 monolignol 运输和氧化下面的分子的机制的当前的知识,讨论木质素汇编的吸引人的还最不听说的方面,并且加亮潜在地帮助澄清植物木质化的谜的技术。Chang-Jun Liu 2012Molecular Plant2012,5,2:9
3iTRAQ protein profile analysis of soybean stems reveals new aspects critical for lodging in intercropping systems显示文摘Soybean is often intercropped with maize,sugarcane,and sorghum.Because of the shade coming from the latter,the soybean stem lodging is often a very serious problem in intercropping systems.The aim of this study is to characterize the possible mechanisms in the stem of shade-induced promotion of seedling soybean lodging in intercropping systems at the proteome level.We found that the soybean stem became slender and prone to lodging when it was planted with maize in an intercropping system.The inhibition of lignin biosynthesis and lack of photosynthate(soluble sugar)for the biosynthesis of the cell wall led to the lower internode breaking strength.A total of 317 proteins were found to be affected in the soybean stem in response to shade.Under the shade stress,the down-expression of key enzymes involving the phenylpropanoid metabolic pathway inhibited lignin biosynthesis.The up-regulation of expansin and XTHs protein expression relaxed the cell wall and promoted the elongation of internodes.Although the expression of the enzymes involving sucrose synthesis increased in the soybean stem,the lack of a carbon source prevented rapid stem growth.This metabolic deficit is the principal cause of the lower cellulose content in the stem of intercropped soybean,which leads to weakened stems and a propensity for lodging.LIU Wei-guo WEN Bing-xiao ZHOU Tao WANG Li GAO Yang LI Shu-xian QIN Si-si LIU Jiang YANG Wen-yu 2019Journal of Integrative Agriculture2019,18,9:1
