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 of the deep knowledge about the flavonoids biosynthesis pathway in cotton, the genetic features underlying its control are not fully understood. Particularly, data on regulatory genes for the proanthocyanidins (PAs) branch are incomplete for the genus Gossypium L.
