Mobile MUTE specifies subsidiary cells to build physiologically improved grass stomata ($)
Plants breathe through pores called stomata on leaf surfaces. Stomata are the point of contact with the outside world as they allow gas exchange (e.g., CO2 for photosynthesis) and transpiration. Grasses have evolved to form more efficient stomata in which the guard cells are flanked by additional subsidiary cells. Therefore, grasses form superior 4-celled stomata […]
