 Abstract
We have previously characterized the complete fibroin light chain gene from one of the silkworm race Baegokjam (Bombyx mori) and found two variable regions (FibL1, intron 2 ~ 3; FibL2, intron 6) with the primer sets designed to cover these variable regions. In this study, we tested the utility of these variable regions as genetic markers for classifying silkworm races. For the purpose, Europian races (Q, PK), Chinese races (C26, C31), Japanese races (N15, N9), and tropical races (SA2, SA5) were used in this experiment. The polymorphism of the FibL1 and FibL2 were divided into two and three types, respectively. The combination of the FibL1 and FibL2 polymorphisms were constant within the same races. The result suggest that the primer sets designed from two variable regions of fibroin light chain gene may be useful as the genetic markers for silkworm races.
