The Arabidopsis embryo establishes polarity and main tissue types with the first five rounds of cell division. In this issue of Developmental Cell, Gooh et al. (2015) provide tools toward elucidating this poorly understood process through the first movies and targeted manipulations of early embryos developing inside cultured seeds.
拟南芥胚胎通过前五轮细胞分裂建立极性和主要组织类型。在本期《发育细胞》中,Gooh 等人(2015)通过对培养种子内早期胚胎的首次电影拍摄和靶向操作,提供了阐明这一过程的工具,该过程目前还了解甚少。
