Abstract

Ovules are initiated in a highly regular pattern along the placenta inside the gynoecia of flowering plants. New research reveals that two separate EPFL peptide-mediated pathways functioning through a set of ERECTA-family receptors coordinate ovule patterning with fruit growth.

摘要

胚珠沿着开花植物雌蕊内的胎座以高度规则的模式起始。新的研究表明，两条通过一组ERECTA家族受体起作用的独立的EPFL肽介导途径，将胚珠模式与果实生长协调起来。
