General Information

General Information Comment Organism
metabolism guard cell walls concerted with the action of cell-wall enzymes, acting on the cell wall polymers for stomatal movements, regulation, overview Arabidopsis thaliana
physiological function pectin is an important cell wall polysaccharide required for cellular adhesion, extension, and plant growth. The pectic methylesterification status of guard cell walls influences the movement of stomata in response to different stimuli. Pectin methylesterase (PME) has a profound effect on cell wall modification, especially on the degree of pectic methylesterification during heat response. Isozyme PME34 plays a significant role in heat tolerance through the regulation of stomatal movement, PME34 specifically regulates stomatal aperture in response to heat, overview. The opening and closure of stomata is mediated by changes in response to a given stimulus, might require a specific cell wall modifying enzyme to function properly Arabidopsis thaliana
