Subject	Rice Root-knot nematode Meloidogyne graminicola

Description	Not Available The rice root-knot nematode, Meloidogyne graminicola, is one of the most important plant-parasitic nematodes present in various production systems in all major rice-growing areas of the world. The vermiform second-stage juvenile (J2) is the infective stage and may be found either inside the roots or in the soil. When in the soil, they penetrate the plant root in the elongation zone. J2s migrate intercellularly through the cortex to the vascular cylinder where they induce the formation of specialized feeding cells, called giant cells, start feeding, and become swollen and sedentary. In contrast to other root-knot nematodes, females deposit their eggs in a gelatinous matrix inside the roots. Hyperplasia and hypertrophy of surrounding cells cause the formation of galls or root-knots, mainly at the root tips and with a characteristic hook-like shape. M. graminicola has a relatively short life cycle on rice (2 to 4 weeks) and can cause 20–33% yield losses in susceptible cultivars. ICAR
