A method for increasing the weight of silk glands of silkworm

Abstract

The invention discloses a method for increasing the weight of silk gland of bombyx mori. According to the sequence pQLTFTSGWGa, bombyx mori adipokinetic hormone A polypeptide synthesis is carried out from a C terminal (carboxyl terminal) to an N terminal (amino terminal); the activity of synthesized bombyx mori adipokinetic hormone A polypeptides is detected by adopting a luciferase reporter gene method; a bombyx mori adipokinetic hormone A active polypeptide solution is degermed by a filtering membrane, and injected into the abdomen of the 5-day bombyx mori in the second day to the third day, the bombyx mori is raised with mulberry leaves to be mature, so that the weight of the silk gland is increased. The method achieves the increase of the weight of the silk gland of the bombyx mori by regulating the distribution of bombyx mori energy by newly discovered active polypeptides without increasing the mulberry leaf eating quantity of the bombyx mori, which has a positive effect on the study of the energy distribution mechanism of the bombyx mori, further improvement of economic characters of the bombyx mori and the like.

Description

technical field

[0001] The invention relates to a synthesis of active polypeptides for increasing the weight of silk glands of silkworms, in particular to a method for increasing the weight of silk glands of silkworms. Background technique

[0002] The silkworm (Bombyx mori) is the silk-producing insect with the largest amount of indoor breeding on the earth today. It absorbs various nutrients from mulberry leaves and supplies them to various tissues and organs in the silkworm through metabolic and physiological processes for growth, development, and reproduction. Nutrients are supplied to the silk glands for silk gland growth. Silk glands are the tissues and organs of silkworms that synthesize silk substances, and the quality of their growth directly affects the amount of silk produced by silkworms. For this reason, adopting various methods to promote the growth of silk glands is one of the important technical measures to improve cocoon silk production in sericulture, and ...
