Molecular plants defense mechanisms against nematodes. Plant Pathology Science 5(2):90-100. Plant parasitic nematodes can devastate a wide range of crop plants. They are obligate parasites and have evolved compatible parasitic relationship with their host plants to obtain nutrients that are necessary to support their development and reproduction. Suppression of host defense is a key step for pathogenesis in the compatible interaction. Plant defense response is activated from the moment a nematode penetrates the plant root. Stylet and secretions of esophageal glands play central roles at during invasion to host, migration inside the roots and establishment of feeding site on host cells. New findings demonstrate that secretions of esophageal glands of some nematodes as effectors deliver into the apoplast and cytoplasm of host cells to active plant defense responses in resistant host. Molecular plants defense mechanisms against nematodes described in this paper. M3 ER -
