In multicellular organisms, stem cells produce various cell types through asymmetric cell division (ACD), which is achieved is through polarization of cell-fate determinant proteins in the ACD progenitor cells. In Arabidopsis stomatal development, an ACD progenitor cell, the meristemoid mother cell (MMC),…

Hosotani et al. explore the molecular mechanisms that modulate stomatal opening under different light conditions. by Sakurako Hosotani and Atsushi Takemiya (Yamaguchi University)  Background: Opening of stomatal pores is essential for photosynthetic CO2 fixation and transpiration in terrestrial…

Guillaume Charrier Université Clermont Auvergne, INRAE, PIAF, F-63000 Clermont-Ferrand, France. guillaume.charrier@inrae.fr Water potential (Ψ) defines the energy required to move water between the different compartments of a closed system. Water flows passively in the direction of decreasing…

Plants communicate with the environment through stomata (i.e., pores found on leaf surfaces) and regulate gas exchange depending on internal and external cues by optimizing stomata density. Still, how plants integrate metabolic and environmental signals remain to be determined. Here, Han and colleagues…

Stomatal conductance, gs, is one of the most important and highly regulated plant processes. Lawson and Matthews review how guard cell metabolism, stomatal anatomy and patterning, and signals from the mesophyll affect gs which in turn affects plant productivity and water use efficiency. This is an excellent…

Stomata are the pores on the plant surface surrounded by a pair of guard cells that control gaseous exchange and water loss. Among the many genes involved in stomatal patterning and development, EPIDERMAL PATTERNING FACTOR 1 (EPF1) and STOMAGEN encode signaling peptides and acts as negative (inhibitor)…

Colonization of the terrestrial environment by land plants (embryophytes), a monophyletic clade that evolved from freshwater streptophyte algae, forever changed Earth by transforming biogeochemical cycles. The evolution of stomata was a key adaptation that allowed the colonization of terra firma. Present…

Galdon-Armero et al. present an image resource that can be used to identify natural variation in leaf epidermal development in tomato. The Plant Cell (2020). https://doi.org/10.1105/tpc.20.00127 By Javier Galdon-Armero and Cathie Martin, John Innes Centre, Norwich, UK Background: Just like our…
