CESA7 is a xylem-specific cellulose synthase that is phosphorylated on one or more serine residues (on either S185 or one of S180 or S181) . It is required for secondary cell wall Biosynthesis. The AraBidopsis contains ten CESA proteins: CESA1 (AT5G44030) , CESA2 (AT4G39350) , CESA3 (AT5G05170) , CESA4 (AT5G44030) , CESA5 (AT5G09870) , CESA6 (AT5G64740) , CESA7 (AT5G17420) , CESA8 (AT4G18780) , CESA9 (AT2G21770) and CESA10 (AT2G25540) .
