Web23 Mar 2015 · Cambium produces secondary xylem on the inner side and secondary phloem on the outer side in both stem and root. Secondary thickening is not commonly observed in leaves (Esau, 1965; Ewers, 1982; Dickinson, 2000 ). In addition, xylem can also differentiate from callus, and this was observed in woody plants more than a century ago (Simon, 1908 ). WebSecondary cell wall (SCW) thickening provides the mechanical force for anther dehiscence and plays an important role in the formation of xylem structure. We have previously reported that γMYB2, a MYB coiled-coil protein, directly binds to the P1BS cis-element of the PLA 2 -γ promoter and acts as a co-activator of γMYB1 in controlling the expression of PLA 2 -γ.
