BREED OF SILKWORM CAPABLE OF PRODUCING SERICIN IN LARGE AMOUNT

摘要

PROBLEM TO BE SOLVED: To obtain a breed of silkworm capable of producing a large amount of sericin by crossing an exarate pupa strain of a mutant species, with a healthy multi-yarn strain of a normal species. SOLUTION: This newly grown breed of silkworm, capable of producing a large amount of sericin can produce a sericin protein which is in large demand as a functional material in various industrial world. The breed can be identified from other breeds of the silkworm by detecting restriction fragments length polymorphism(RFLP) of a silkworm chromosome DNA by using a silkworm cDNA derived from a gene carried by each of 28 pairs of silkworm chromosomes as a probe.
