Description
Stomata are tiny pores on leaves that open and close to trade gases, and they also serve as entry points that plants must defend. Matěj Drs and co-authors studied two parts of a delivery system called the exocyst in the model plant Arabidopsis in 2025. Plants missing either part had shown defense problems in earlier work, and the team looked for the underlying cause.
Mutant plants started with more closed stomata than normal. Their cell walls also carried changed chemical marks on pectin and related fibers, which may weaken defense both through the pores and beyond them. Gene activity data pointed to candidate genes for these effects. The two mutants differed when young but converged as adults.
