Plant endogenous gene influencing feeding of lepidoptera insects and protein of plant endogenous gene

Abstract

The invention provides a plant endogenous gene influencing lepidoptera insect feeding and a protein thereof. The plant endogenous protein can influence the plant feeding amount of insects, and the amino acid sequence of the protein is as shown in SEQ ID No.2.

Description

technical field [0001] The invention relates to a plant endogenous gene and its protein that affect the feeding of lepidopteran insects, especially the homozygous plants that lack or silence the gene can acquire resistance to lepidopteran insects. Background technique [0002] In agricultural production, pests are one of the important reasons affecting crop yield and quality, and cause huge economic losses to farmers every year. Lepidoptera includes two classes of insects, moths and butterflies, belonging to the subclass Pteroptera and holometabolism. This order is the second largest order after Coleoptera in Insecta, with a wide range of distribution and the most abundant species in the tropics. Most types of larvae damage all kinds of cultivated plants, and the larger ones often eat up the leaves or drill into the branches. Smaller ones tend to curl leaves, adorn leaves, form sheaths, spin silk and form nets, or drill into plant tissues to feed and cause damage. Adults ...

Problems solved by technology

At present, the control of crop pests mainly relies on chemical pesticides, but chemical pesticides have a pungent smell and pose a serious threat to the environment and human health. Therefore, mining natural insecticidal materials from natural resources has attracted more and more attention.
