DEVELOPMENT Patterns of Stomatal Development in Leaves

The pattern of stomata on plant epidermis is developmentally regulated to support even but adjustable gaseous exchange for the plant. Bergmann et al. (see the Perspective by Sack) now show that the MAPKK kinase, YODA, serves to regulate cell fate in the developing epidermis and to manage the differentiation of stomatal guard cells. Bioinformatics analysis helped identify additional genes likely to regulate stomatal development and function, including a putative transcription factor, FAMA, which shows its highest expression in leaves.
