Polar transport of the signaling molecule auxin is critical for plant development and depends on both the polar distribution of auxin efflux carriers, which pump auxin out of the cell and the alignment of these polarized cells. Two papers in this issue of Cell (Michniewicz et al., 2007; Jaillais et al., 2007) address how polar transport of these carriers occurs and describe the endosomal pathways involved.
信号分子生长素的极性运输对植物发育至关重要,它依赖于生长素外流载体的极性分布,这些载体将生长素泵出细胞以及这些极化细胞的排列。本期《细胞》杂志上的两篇论文(Michniewicz等人,2007年;Jaillais等人,2007年)探讨了这些载体的极性运输是如何发生的,并描述了其中涉及的内体途径。
