Prospects for enhancing leaf photosynthetic capacity by manipulating mesophyll cell morphology.

abstract：:Ascorbate peroxidase (APX) exists as several isoforms that are found in various compartments in plant cells. The cytosolic and chloroplast APXs appear to play important roles in antioxidation metabolism in plant cells, yet the function of peroxisomal APX is not well studied. In this study, the localization of a putati...
