In-Depth Information
AtMYB20; A. thaliana
High level of expression in IF and xylem
cells undergoing SW thickening.
Regulator of SW biosynthesis.
Zhong et al. (2008)
KNAT7; A. thaliana
High level of expression in IF and xylem
cells undergoing SW thickening. DR
significantly reduced SW thickening in
fibre cells. KO mutants increased SW
thickness of IF while KNAT7 OE
mutants have the opposite phenotype.
Repressor of SW biosynthesis in
Arabidopsis and poplar. Induces SW
biosynthetic genes. Direct target of
SND1 and its close homologs, NST1,
NST2, VND6, VND7 and their
downstream target AtMYB46.
Interacts with PAP1.

VvWRKY2; V. vinifera
Specifically expressed in cells undergoing
lignification. OE of VvWRKY2 in
tobacco decreases S/G ratio.
Regulator of SW possibly in response
to biotic and abiotic stresses.
Activator of VvC4H.

ANS, anthocyanidin synthase; IF, interfascicular fibres; DR, dominant repression; OE, overexpression; SX, secondary xylem; SW, secondary cell wall.
