图5 中柱鞘和内皮层在水稻侧根原基建成过程中的形态变化 A: 中柱鞘中的PFCs和生长素峰; B: 正对着PFCs的相邻内皮层细胞在高浓度生长素刺激下的形态变化; C, D: PFCs和内皮层细胞各自进行分裂形成的两部分侧根原基结构; E: 发育出基部输导组织和顶端生长点的成熟侧根原基。
Fig. 5 Morphological changes of pericycle and endodermis during LPR formation A: PFCs in pericycle and the auxin peak; B: stimulated by the high concentration of auxin in PFCs, morphological changes occurred in the adjacent endodermis; C, D: PFCs and endodermis cells divided respectively and formed two parts of lateral root primordia; E: mature lateral root primordia with apical meristem and basal conducting tissues.
