Abstract
Resistance in plants is influenced by
resistance genes. Those genes give the defense signals against insect, disease
and nematodes. Hypersensitive reaction is happened at the nematode feeding
site. Chitosan is considered as the best biopolymer next to cellulose. It
possesses anti-fungal, anti-bacterial and anti-nemic properties. Chitosan
indirectly enhances the resistance pathways such as Jasmonic acid and salicylic
acid. Nanotechnology plays a major role for the formulation of chitosan
nanospheres. Ionic gelation method is commonly used to develop a chitosan
nanospheres. Those nanoparticles easily increase the production of phytoalexins
and Reactive Oxygen Species in plants. Several treatments were taken for GCMS
analysis such as Nematode (M. incognita), Chitosan nanospheres 1%
@2ml/plant + Nematode (1 week after chitosan nanospheres application) and
Control. The two compounds viz., 9- Octadecenoic acid (Z)-2, 2-
(acetyloxy)-1 [(acetyloxy) methyl] ethyl ester and 6-bromohexanoic acid of
jasmonate pathway were present in chitosan nanospheres treated tomato plants
but absent in untreated plants.
