Abstract

The shapes of flowers and their organization into branching systems, called inflorescences, dictate much of plant diversity. Recent studies have identified key regulators in this diversity, revealing that the inflorescence architecture of Solanaceous species depends on sequential and temporal expression of the WUSCHEL-RELATED HOMEOBOX (WOX) gene EVERGREEN (EVG)/ COMPOUND INFLORESCENCE (S) and the UNUSUAL FLORAL ORGANS (UFO) ortholog DOUBLE TOP (DOT)/ANANTHA (AN).

摘要

花朵的形状及其组成的分支系统（称为花序）在很大程度上决定了植物的多样性。最近的研究已经确定了这种多样性中的关键调控因子，揭示了茄科植物的花序结构取决于与WUSCHEL相关的同源异型框（WOX）基因常绿（EVG）/复合花序（S）以及异常花器官（UFO）直系同源基因双头（DOT）/无花（AN）的顺序和时间表达。
