v-myb avianmyeloblastosis viral oncogene homolog (MYB) transcription factors are key regulators of stress responsive gene expression in plants. In this study, the MYB gene, ChiMYB (GenBank accession No. KT948997), was isolated from Chrysanthemum indicum, and was functionally characterized with an emphasis on salinity stress tolerance. The full ChiMYB cDNA sequence (948 bp) encoded a typical R2R3 MYB transcription factor that contained 315 amino acid residues and two MYB domains. The temporal expression pattern of ChiMYB was noted in C.
Spontaneous leaf color variation in bamboo provides the opportunity to study the mechanisms of leaf color formation and the breeding of ornamental bamboos. Despite the fact that many genes are known to be involved in leaf color variation in model plants, molecular mechanisms governing natural leaf color variation in bamboo have remained obscure. This study aimed to identify the genes responsible for the occurrence of such phenomena in bamboo using the suppression subtractive hybridization (SSH) method between green and albino leaves in Pseudosasa japonica f.
