Abstract
Tomato (Solanum lycopersicum L., 2n=2x=24) is an important vegetable for
human consumption because of its enriched nutritional composition that provide the
basic body nutritional requirements. In recent years, it has attracted the attention due
to the anti-carcinogenic and antioxidant property of lycopene and ascorbic acid.
Tomato (S. lycopersicum L.) is affected by various diseases caused mainly by fungi,
bacteria and nematodes. Root-knot nematodes (Meloidogyne spp.) found to be very
fatal infective agents and cause severe yield loses. The present investigation was
undertaken to enhance understanding regarding the molecular and biochemical
changes that takes place in the tomato seedlings under root knot biotic stress. Better
understanding about the exact mechanism of plant response towards such biotic stress
can help to improve screening strategies for the selection of resistant cultivars. Two
tomato cultivars AT 3 (Susceptible) and SL 120 (Resistant) grown under sterile and
root knot nematode (3000 J2 stage larvae per plant) inoculated soil were used for
differential gene expression and proteomics study during root knot nematode
(Meloidogyne incognita) infection in tomato (S. lycopersicum L.).
