Vascular-related NAC-domain transcription facor (VND)is one group of the largest plant-specific transcription factor NAC family. The VND1-VND7 were orginally isolated as genes for which expression levels are elevated during transdifferentiation into trachery elements, in a induction system using Arabidopsis suspension cells [1]. | == Overview == | ||
Vascular-related NAC-domain transcription facor (VND)is one group of the largest plant-specific transcription factor NAC family. The VND1-VND7 were orginally isolated as genes for which expression levels are elevated during transdifferentiation into trachery elements, in a induction system using Arabidopsis suspension cells [1].VNDs are grouped in NAC-c subfamily [2]. Typically, the proteins in this subfamily share a well conserved N-terminal NAC domain (-150 amino acid;aa) and a diversified C-terminal transcription regulatory region [3,4]. The N-terminal NAC domain is usually responsible for DNA binding and dimerization, and the C-terminal NAC domain function in transcription activation , repression and protein binding. | |||
