The appearance of stomatal pores during plant evolution is believed to have been a crucial step in land colonisation. A recent screen for genes involved in stomatal development has identified for the first time a mutant plant with no stomata; the results implicate a MAP kinase cascade in stomatal development.
气孔在植物进化过程中的出现被认为是植物在陆地上定殖的关键一步。最近一项针对参与气孔发育的基因的筛选首次鉴定出一种没有气孔的突变植物；研究结果表明丝裂原活化蛋白激酶级联反应参与气孔发育。
