Identification of TT2 gene from floral transcriptome in Fagopyrum tataricum

In plants, the MYB family transcription factor has selectively expanded, particularly through the large family of R2R3-MYB. MYB proteins are key factors in regulatory networks controlling development, metabolism and responses to biotic and abiotic stresses. AtMYB123/TT2 encodes a R2R3 type MYB transcription factor, and plays a key role in regulating flavonoid late biosynthetic genes in Arabidopsis. Here, we firstly identified a TT2/AtMYB123 homologous protein FtMYB123L through bioinformatics analysis from the floral transcriptome data from Fagopyrum tataricum. We speculate that FtMYB123L also involves the regulation of flavonoid biosynthesis in F. tataricum. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.
