[Abstract]  Plants maintain capacity to form new organs such as leaves, flowers, lateral shoots and roots throughout their postembryonic lifetime. Lateral roots (LRs) originate from a few pericycle cells that acquire attributes of founder cells (FCs), undergo series of anticlinal divisions, and give rise to a few short initial cells. After initiation, coordinated cell division and differentiation occur, giving rise to lateral root primordia (LRP). Primordia continue to grow, emerge through the cortex and epidermal layers of the primary root, and finally a new apical meristem is established taking over ... [摘要]  植物在其胚后期内保持形成新的器官,例如叶,花,侧枝和根的能力。侧根(LR)源于几个获得创始细胞(FC)属性的周围细胞,经历一系列的背脊分裂,并产生几个短的初始细胞。起始后,发生协调的细胞分裂和分化,产生侧根原基(LRP)。原始状态继续生长,通过主根的皮层和表皮层出现,并且最终建立新的顶端分生组织,承担成熟侧根生长的责任[关于侧根根器官发生的各个阶段的详细描述,参见Malamy和Benfey(1997)]。为了检查这种高度动态的发育过程并且调查各种激素,遗传和环境因素在侧根器官发生的调节中的作用,基于实时成像的分析代表非常有力的工具(Laskowski等人 ,2008; De Smet等人,2012;Marhavý等人,2013;Marhavý等人,2014)。在这里,我们描述了用于实时侧根原基(LRP)分析的协议,其使得能够在原始器官发生期间监测特定基因表达和亚细胞蛋白定位的发生,以及评估遗传和环境扰动的影响对LRP器官发生的影响。
