In silico analysis of the regulatory gene families for proanthocyanidins biosynthesis in the genus Gossypium L.

The flavonoid pigments provide cotton cultivars with various shades of the naturally colored fiber. Despite deep knowledge about flavonoids biosynthesis pathway in cotton, genetic features underlying its control are not fully understood. Particularly, data on regulatory genes for proanthocyanidins (PAs) branch incomplete genus Gossypium L. Here we report results comprehensive silico analysis R2R3-Myb, bHLH-Myc and WD40 gene families, involved pigment PAs cotton. For first time, identified WD40, including paralogous homoeologous copies, among all sequenced diploid allotetraploid species: G. hirsutum L., barbadence raimondii arboreum All duplication events occurred genome common ancestor were supported by a negative evolution (Ka/Ks < 1). However, GhTTG1/GhTTG3 proved to be most conservative predominantly selection, while GhTT2/GhMYB10 GhTT8 more variable suitable further analysis. thorough study has suggested that genes, exception GhTT8-A2, possibly biosynthesis. Therefore, information structural organization functionality MBW is represented here. Revealing allelic diversities associating contrast phenotype, may useful marker-assisted selection or editing creation agriculturally valuable traits.
