In this issue of Developmental Cell, Marhavý et al. (2011) uncover a transcription-independent molecular mechanism of interaction between auxin and cytokinin in the regulation of plant meristem function. By modulating endocytic trafficking of PIN1, cytokinin controls auxin flux and, therefore, auxin gradients.
在本期《发育细胞》中,Marhavý 等人(2011 年)揭示了生长素和细胞分裂素在调控植物分生组织功能中的一种转录独立的分子互作机制。通过调节 PIN1 的内吞运输,细胞分裂素控制了生长素的流动,从而控制了生长素的浓度梯度。
