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.

본 실험에서는 누에 피브로인 L-chain 유전자의 인트론 영역을 사용하여 우리나라에서 보존하고 있는 누에 계통중 원산지별 누에 계통 8개를 대상으로 계통 간 유전자다형성을 비교하였다. 실험 결과, 실험에 사용한 누에 계통에 따라서 동일한 계통 내 모든 개체에서 FibL1과 FibL2의 유전자다형성 조합이 일정하게 유지되어 있었으며, 계통 간에는 FibL1과 FibL2의 유전자 다형성 패턴 조합이 다소 상이한 것으로 확인되었다. 따라서, 프라이머 FibL1와 FibL2에 의한 피브로인 L-chain 유전자 다형성 염기서열 정보를 활용한다면 제한된 영역에서 누에 계통 구분을 위한 지표로 활용할 수 있을 것으로 사료된다.
