Genes Related to Anthocyanin Biosynthesis in Purple Leaf B.rapa
Purple leaf Chinese cabbage has anthocyanidins,which is one of breeding aims of inner heading colors.Anthocyanidins are often combined with one or more glycosides,which are called anthocyanins.Anthocyanins,a major group of flavonoid compounds,are responsible for the purple,red and blue colors of leaves,sprout leaves and stems.Anthocyanins,powerful antioxidants,perform several key biological functions,such as attracting pollinators in plants,protecting cells from high-light damage by absorbing blue-green and UV light,and playing beneficial health roles against cancer,senile and oxidative diseases.Four main origins of purple leaf Chinese cabbage could be certified,which were red leaf mustard (Brassica juncea Coss.),purple leaf pakchoi and purple caixin (Brassica rapa L.ssp.chinensis),red turnip (Brassica rapa L.ssp.rapifera).Varieties of purple leaf Chinese cabbage absorb consumer's attraction because they can serve the nutritional qualities of anthocyanins,special favor and beautiful colors.The genes in controlling anthocyanin biosynthesis in B.rapa were received considerable research attentions.Source and heredity of purple leaf color,fine mapping,cloning,functional analysis and expression of genes in controlling anthocyanin biosynthesis in B.rapa were reviewed in the article in order to clone and testify the genes related to anthocyanin biosynthesis further.
