Plant reproduction is initiated by the specification of sporocytes that form haploid spores through meiosis. A new study in Arabidopsis published in Cell Research shows how the product of sporocyteless/nozzle, a key gene in this process, partners with co-repressors and transcription factors to promote spore formation, and draws interesting parallels with fungi.
植物繁殖由孢子母细胞的特化启动，孢子母细胞通过减数分裂形成单倍体孢子。发表于《细胞研究》的一项关于拟南芥的新研究揭示了该过程中的关键基因——无孢子/无柱头的产物如何与共抑制因子和转录因子协同作用以促进孢子形成，并与真菌形成了有趣的对比。
