ABSTRACT Calcium (Ca2+) as a universal signal molecule plays pivotal roles in plant growth and development. It regulates root morphogenesis mainly through mediating phytohormone and stress signalings or affecting these signalings. In recent years, much progress has been made in understanding the roles of Ca2+ in primary root development. Here, we summarize recent advances in the functions and mechanisms of Ca2+ in modulating primary root growth in plants under normal and stressful conditions.

Ca2+调控植物初生根生长的作用及机制

摘要 钙（Ca2+）作为一种通用信号分子，在植物生长发育中起着举足轻重的作用。它主要通过介导植物激素和胁迫信号或影响这些信号来调节根的形态发生。近年来，在理解 Ca2+ 在初级根发育中的作用方面取得了很大进展。在这里，我们总结了 Ca2+ 在正常和胁迫条件下调节植物初生根生长的功能和机制的最新进展。
