Abstract
Stomata play important roles such as gas exchange, through which plants absorb CO2 and release O2 to their environment. MC79 was isolated as a responsible gene for the Arabidopsis thaliana mutant, which showed the morphologically abnormal stomata. The MC79 encodes a leucine rich repeat receptor like kinase. To examine the expression and the intracellular localization of MC79, we produced the PMC79:MC79-GFP transgenic plant. MC79-GFP was detected in the meristemoid and guard mother cell (GMC), and localized at surrounding plasma membrane. Since the expression of MC79 disappeared in guard cells (GC), we considered morphogenesis of GC is determined by transient expression of MC79. We hypothesized that MC79 is involved in the signal transduction pathway determine the morphogenesis of GC during GMC stage.
