“…In Arabidopsis, the CESA gene family has 10 members (Richmond, 2000): CESA1, CESA3, CESA6, and CESA6-like (CESA2, CESA5, and CESA9) are involved in primary cell wall biosynthesis (Arioli et al, 1998;Fagard et al, 2000;Scheible et al, 2001), CESA4, CESA7, and CESA8 are involved in secondary cell wall biosynthesis (Turner and Somerville, 1997;Taylor et al, 1999Taylor et al, , 2003, and CESA10 appears to function in the production of seed coat mucilage (Griffiths et al, 2015). Specifically for primary wall CSCs, biochemical and genetic studies have indicated that CESA1 and CESA3 are constitutive components of the CSC, whereas CESA6 and CESA6-like proteins have partially redundant functions and likely constitute a third catalytic component of the CSC (Desprez et al, 2007;Persson et al, 2007).…”
