CRISPR/Cas9-induced knockout of an amino acid permease gene (AAP6) reduced Arabidopsis thaliana susceptibility to Meloidogyne incognita.

Background: Plant-parasitic root-knot nematode (Meloidogyne incognita) causes global yield loss in agri- and horticultural crops. Nematode management options rely on chemical method. However, only a handful of nematicides are commercially available.

Induced knockdown of and perturbed the host seeking behavior of in rice.

Root-knot nematode is one of the most destructive plant parasites in upland as well as direct seeded rice. As an integral part of nematode biology, host finding behavior involves perceiving and responding to different chemical cues originating from the rhizosphere. A sustainable management tactic may include retardation of nematode chemoreception that would impair them to detect and discriminate the host stimuli.

Molecular and functional characterization of chemosensory genes from the root-knot nematode Meloidogyne graminicola.

Background: Root-knot nematode Meloidogyne graminicola has emerged as a major threat in rice agroecosystems owing to climate change-induced changes in cultivation practices. Synthetic nematicides are continually being withdrawn from the nematode management toolbox because of their ill effects on the environment. A sustainable strategy would be to develop novel nematicides or resistant plants that would target nematode sensory perception, which is a key step in the host finding biology of plant-parasitic nematodes (PPNs).
