Background

CesA7 (IRX3) is a catalytic subunit of xylem-specific cellulose synthase, involved in secondary cell wall biosynthesis - cellulose synthase trerminal complexes. It interacts with CESA4 and CESA8 which is required for a functyional complex and localization in secondary cell wall deposition sites. Occurs in secondary cell wall developing tissues such as xylems and interfascicular regions in young plants stems and flowers. Not expressed in leaves, roots and shoots.
