LEA家族基因参与仁用杏花期调控的分子机制
Genome-wide analysis and functional analysis of late embryogenesis abundant(LEA)genes during dormancy and sprouting periods of kernel-using apricots(P.armeniaca L.×P.sibirica L.)
[目的]仁用杏具有很高的经济价值和生态价值,是我国"三北地区"重要的生态经济型干果树种、木本油料树种和植物蛋白饮料树种。由于仁用杏休眠期短、花期早,易遭受晚霜为害,造成减产甚至绝产,因此了解低温条件下仁用杏花期调控的响应机制,实现花期的人为调控是解决仁用杏低产和不稳产的有效途径之一。[方法]该研究以拟南芥AtLEAs和杨树PtLEAs 序列为种子序列,通过 blast在仁用杏"龙王帽"基因组中鉴定胚胎发育晚期丰富蛋白(Late embryogen…查看全部>>
[Objective]The aim of this study was to Understand the response mechanism of regulating the flowering period of kernel-using apricots(P.armeniaca L.×P.sibirica L.)under low temperature and achieving artificial regulation of flowering period is one of the effective ways to solve the problem of low and unstable yield of kernel apricot.[Method]The predicted peptide sequences of LEA members were acquired from the genome database(unpublished)of kernel-using apric…查看全部>>
