Comparative histopathology of virulent and avirulent populations on susceptible and resistant tomato plants.

The 1.2 gene confers resistance to a wide range of species, being the most important resistance factor employed in tomato breeding so far. However, many aspects related to the interaction of 1.

Molecular Techniques for Root-Knot Nematode Identification.

Among plant-parasitic nematodes, root-knot nematodes (RKN), Meloidogyne spp., are the most important parasite infecting economically important crops globally and causing severe losses in crop production. The use of efficient nematode control methods against these parasites depends upon their correct detection in roots and soil samples.
