In vascular vessel, VND6 and VND7 control both secondary cell development and programmed cell death of vessels in both root and shoot tissues (1,33). The over-expression of VND6 and VND7 can induce ectopic differentiation of two different types of vessel elements: proto-xylem, and meta-xylem vessels. Reversely, the functional repression of VND6 and VND7 can inhibit vessel element formation. Additionally, the poplar VNDs can complement the Arabidopsis cell wall development defective mutant NST1NST3, suggesting that VNDs share the conserved functions with other secondary cell wall regulators [34]. | In vascular vessel, VND6 and VND7 control both secondary cell development and programmed cell death of vessels in both root and shoot tissues (1,33).
