As master transcription factors of stomatal development, SPEECHLESS, MUTE, and FAMA, collectively termed SMFs, are primary targets of molecular genetic analyses in the model plant . Studies in other model systems identified SMF orthologs as key players in evolutionary developmental biology studies on stomata. However, recent studies on the astomatous liverwort revealed that the functions of these genes are not limited to the stomatal development, but extend to other types of tissues, namely sporophytic setal and gametophytic epidermal tissues. These studies provide insightful examples of gene-regulatory network co-opting, and highlight SMFs and related transcription factors as general toolkits for novel trait evolution in land plant lineages. Here, we critically review recent literature on the SMF-like gene in and discuss their implications for plant evolutionary biology.
作为气孔发育的主转录因子，无口、沉默和FAMA统称为SMFs，是模式植物分子遗传分析的主要靶点。在其他模式系统中的研究确定SMF直系同源物是气孔进化发育生物学研究中的关键参与者。然而，最近对无气孔地钱的研究表明，这些基因的功能不仅限于气孔发育，还扩展到其他类型的组织，即孢子体蒴柄和配子体表皮组织。这些研究提供了基因调控网络互作的深刻例子，并突出了SMFs和相关转录因子作为陆地植物谱系新性状进化的通用工具包。在这里，我们批判性地回顾了关于[具体植物]中SMF样基因的最新文献，并讨论了它们对植物进化生物学的意义。
