Abstract
Stomata are micropores that allow plants to breathe and play a critical role in photosynthesis and nutrient uptake by regulating gas exchange and transpiration. Stomatal development, therefore, is optimized for survival and growth of the plant despite variable environmental conditions. Signaling cascades and transcriptional networks that determine the birth, proliferation, and differentiation of a stomate have been identified. These networks ensure proper stomatal patterning, density, and polarity. Environmental cues also influence stomatal development. In this review, we highlight recent findings regarding the developmental program governing cell fate and dynamics of stomatal lineage cells at the cell state- or single-cell level. We also overview the control of stomatal development by environmental cues as well as developmental plasticity associated with stomatal function and physiology. Recent advances in our understanding of stomatal development will provide a route to improving photosynthesis and water-stress resilience of crop plants in the climate change we currently face.
Highlights
When plants transition from water to land, they became more exposed to carbon dioxide (CO2) and arid conditions
This study suggests potential regulators of stomatal development and a possible genetic network: BASIC PENTACYSTEINE (BPC) gene family and WRKY33 genes are highly expressed in the MMC through guard mother cells (GMCs) state
This study identified CO2 RESPONSE SECRETED PROTEASE (CRSP), which is induced by elevated CO2 level and encodes a protease that cleaves the precursor of EPF2 to release the mature peptide into the apoplast
Summary
When plants transition from water to land, they became more exposed to carbon dioxide (CO2) and arid conditions. The R2R3-MYB transcription factor FLP functions redundantly with FAMA for stomatal differentiation and direct repression of the cell cycle genes (Xie et al, 2010; Lee et al, 2014b). Induced MUTE expression in wild-type plants did not show the clustered stomata phenotype due to full differentiation of stomatal lineage cells (Trivino et al, 2013).
