Expression differences of flavonoid synthase I（BmFNS I）gene in the midgut,silk gland and fat body of the male and female Bombyx Mori with sex-identified fluorescent cocoon color were detected by fluorescence quantit...Expression differences of flavonoid synthase I（BmFNS I）gene in the midgut,silk gland and fat body of the male and female Bombyx Mori with sex-identified fluorescent cocoon color were detected by fluorescence quantitative PCR.The result showed that the relative expression level of BmFNS I gene in midgut of Bombyx Mori was the highest,followed by that in fat body,and the expression level in silk gland was the lowest,indicating that BmFNS I gene played an important role in flavonoids anabolism in mulberry leaves,which was the food of silkworm.However,there was no significant difference in BmFNS I gene expression level between midguts of male and female Bombyx Mori species with sex-identified fluorescent cocoon color,suggesting that there was no difference in flavonoids anabolism of mulberry leaves between the male and female Bombyx Mori with sex-identified fluorescent cocoon color,at least no difference in flavonoids anabolism regulated by FSN I gene.展开更多
