The power of small: microRNAs modulating stomatal movement

Marcelle Ferreira-Silva et al. Trends Plant Sci. 2025 Feb.

Abstract

Regulation of stomatal aperture is paramount in drought-stress responses. Recently, Yang et al. demonstrated how microRNA-plantacyanin (PCY) regulates stomata movement by revealing a novel mechanism responsive to abscisic acid (ABA) that controls reactive oxygen species (ROS) in guard cells. This sets a precedent for using miRNAs as a new target for stress-resistance genetic engineering.

Keywords: ROS; drought stress; guard cell; miR408.
