Stomata are cellular structures that control water loss and gas exchange through the plant epidermis. Stomata arise from special stem cells called meristemoids through a series of programmed asymmetric divisions that are controlled by cell signaling, or via multitude of regulatory pathways and intercellular communication between epidermal cells. In Arabidopsis thaliana, stomata are spaced non-randomly in the epidermis by cell-cell signaling of the receptor-like protein TOO MANY MOUTHS (TMM) as well as other proteins. Point mutation of the TMM gene prevents the development of stomata in some tissues like inflorescence stems. Investigation of tmm mutant stems showed that self-renewing stem …
