AI Technical Summary
Root-knot nematodes cause serious damage and there is a lack of resistant resources. Chemical control leads to pesticide residues and resistance, making it difficult to meet the needs of green agriculture.
The nematicidal peptide Peptide-2 derived from Bacillus licheniformis was optimized using bioinformatics technology. By introducing methionine at the amino terminus and adjusting the number of positively charged residues and hydrophobic characteristics, it was optimized into a highly lethal nematicidal peptide.
Peptide-2 exhibits high lethality against root-knot nematodes and a high corrected mortality rate, meeting the needs of green agriculture for the development of biocontrol agents and the creation of new germplasm resources for root-knot nematode-resistant crops, thus overcoming the shortcomings of chemical control.
