Localized maxima of the plant hormone auxin are crucial to root development and meristem maintenance. In this issue of Developmental Cell, Brumos et al. used elegant genetic and grafting experiments to distinguish between the contributions of local and distal auxin sources to auxin maxima generation and root meristem maintenance.
植物激素生长素的局部最大值对根发育和分生组织维持至关重要。在本期《发育细胞》中,Brumos 等人利用巧妙的遗传和嫁接实验,区分了局部和远端生长素源对生长素最大值产生和根分生组织维持的贡献。
