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 present invention relates to a plant endogenous gene and its protein that affect the feeding of lepidopteran insects, in particular, the homozygous plant after deletion or silencing of 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, causing huge economic losses to farmers every year. Lepidoptera includes two types of insects, moths and butterflies. This order is the second largest order in the class of insects after Coleoptera, with a wide distribution range, with the most abundant tropical species. Most species of larvae damage all kinds of cultivated plants, and the larger ones often eat up leaves or bore through branches. Smaller ones tend to roll leaves, tie leaves, knot sheaths, spin silk and net or drill into plant tissues to feed. Adults mostly use nectar as supplementary nutrition, or the mouthparts ...

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.
