Identification and expression analysis under abiotic stress of the R2R3-MYB genes in Ginkgo biloba L.

ABSTRACT: The R2R3-MYB gene family is the largest MYB subfamily in plants and is involved in the regulation of plant secondary metabolism and specific morphogenesis, as well as the response to biotic and abiotic stress. However, a systematic identification and characterization of this gene family has not been carried out in Ginkgo biloba. In this study, we performed a transcriptome-wide survey from four tissues of G. biloba to determine the genetic variation and expression pattern of the R2R3-MYB genes. We analyzed 45 GbMYBs and identified 42 with a complete coding sequence via conserved motif searches. The MYB domain and other motifs in GbMYBs are highly conserved with Arabidopsis thaliana AtMYBs.
