In leaves, pattern distribution is highly variable between species but regulated by mechanism that maintains minimum one spacing stomata. Arabidopsis, number components this have been identified include, SDD1, EPF1 putative receptors TMM ERECTA-gene family. A mitogen-activated protein (MAP) kinase signalling cascade believed to act downstream these while transcription factors including SPCH, MUTE FAMA consecutive steps development. The environment also has significant effects both light intensity CO2 concentrations shown influence frequency at which stomata develop leaves. Long-distance mechanisms implicated environmental responses with conditions sensed mature leaves determining developing Thus, changes appear modulating developmental pathways determine frequency.
