条件QTL分析是一种根据作物生长特定阶段或相关性状(措施)等给定条件下的净遗传效应,分析数量性状基因时空表达和互作效应的遗传分析方法.传统QTL(也称非条件QTL)定位一般基于性状终端(或阶段终端)的累积遗传效应值,而条件QTL基于给定条件的净增加效应值.

小麦1B/1R易位系是指小麦的1B染色体短臂1BS被黑麦的1R染色体短臂1RS取代而形成的小麦-黑麦异位系,1RS上具有抗病、抗逆和高产相关基因,自20世纪70年代引入我国以后,在小麦育种中得到了广泛的应用.
赤霉病是由禾谷镰刀菌引起的一种毁灭性小麦病害.由于抗赤霉病资源匮乏以及抗性遗传的复杂性,通过常规育种方法培育抗赤霉病小麦品种是一件费时、费力的工作.望水白是起源于我国江苏的一个优秀赤霉病抗源,但在育种中被成功利用的例子不多.

土壤盐渍化、干旱、低温、高pH和低K+等逆境是植物生长发育的主要环境限制因素,而植物中CBL (Calcineurin B-like proteins,CBL)感受器与其相互作用的蛋白激酶CIPK(CBL-interacting protein kinase,CIPK)构成的Ca2+-CBL-CIPK信号系统能够感知这些逆境胁迫并进行传导,从而调控特异性的生理生化过程.
小麦分蘖发生及成穗是获得稳定群体的重要保证,而小麦分蘖与次生根具有较好的同伸关系,在两极分化时期,较多的次生根有利于分蘖成穗、提高有效分蘖数.细胞分裂素(CTK)是参与小麦次生根发育的主要激素之一,其受体蛋白基因TaCRE1突变势必影响CTK功能,进而影响次生根发育.
Small GTP-binding proteins regulate diverse processes in eukaryotic cells such as signal transduction, cell proliferation, cytoskeletal organization, and intracellular membrane trafficking.
Jacalin-related lectins (JRLs) are carbohydrate-binding proteins widely present in plants and have one or more jacalin domains in common.However, JRLs structural types and functions are still poorly u
