Plant induced resistance in solanacearum lycopersicum species against root knot nematodes

Abstract

The impact of root-knot nematodes of the tomato, Solanacearum lycopersicum, has resulted in severe damage and reduction in crop yields of both temperate and tropical agriculture systems. Keeping in mind the economic significance of the plant, the parasitic nematodes have not only been a burden for plant production but also cause for global agricultural economy depletion. At present, various countries have banned the nematicides after analyzing their consequence on environment and humans thereby making it an imperative to find an alternative method for the inhibition of nematodes against S. lycopersicum. With the plant root comprising of several bioactive secondary metabolites, a self-defense mechanism can be initiated against the infecting parasites. Not with standing, limited research has been carried out to understand the efficacy of induced resistance between or within the same species. Hence, the current review, we summarize on how hypersensitivity-like reactions can enhance plant resistance inducers in solanaceous species and their effects of various root metabolisms, chemical compounds which can act as repellents, hatching stimulants, attractant, or as inhibitors. The review focuses on the objective of understanding the mechanistic intricacies of how RNA interference acts on a root-knot nematode.
