During early embryogenesis, flowering plants establish their principal body plan starting with an apical-basal axis. An asymmetric division of the zygote gives rise to apical and basal cells with different developmental fates. Besides WOX (WUSCHEL-RELATED HOMEOBOX) transcription factors and the plant hormone auxin, the YDA (YODA)/MAPK (mitogen-activated protein kinase) pathway plays a major role in establishing different cell fates after the first zygotic division. In the present review, we summarize the available data on YDA signalling during embryogenesis. The role of YDA in other developmental processes was taken into account to highlight possible implications for this pathway in the embryo.
在早期胚胎发生过程中，开花植物从顶 - 基轴开始建立其主要的身体结构。合子的不对称分裂产生了具有不同发育命运的顶端细胞和基部细胞。除了WOX（WUSCHEL相关同源框）转录因子和植物激素生长素外，YDA（YODA）/MAPK（丝裂原活化蛋白激酶）途径在合子第一次分裂后建立不同的细胞命运中起主要作用。在本综述中，我们总结了胚胎发生过程中YDA信号传导的现有数据。我们还考虑了YDA在其他发育过程中的作用，以突出该途径在胚胎中的可能影响。
