<p>Some strains of silkworms produce green cocoons of varying intensities. This results from quantitative and qualitative differences in flavonoid pigments, which are influenced by the environment and genetic background. We discovered that the appearance of a faint green cocoon is regulated by a gene (G27) located on chromosome 27. Through mating experiments, we found that G27 is identical to an essential flavonoid cocoon gene, Ga. This locus has not been previously described. Furthermore, we narrowed down the Ga region to 438 kbp using molecular markers. Within this region, several predicted genes for sugar transporters form a cluster structure, suggesting that Ga is among them.</p>
