My main research interest is focused on plant-nematode interactions and analysis of cytological changes induced in plants by biotic and abiotic stresses. Cytological, physiological and morphological studies in resistant and susceptible plant species challenged by root-knot and cyst nematodes such as tomato cultivars-Meloidogyne incognita, pea lines-Heterodera goettingiana, wheat lines-H. avenae have been performed.
My background experience is in cytology, physiology and ultrastructure of plants and nematodes; cytochemical and immunocytochemical analysis of both ROS (H2O2, O2-) and enzymes (peroxidases, lipoxygenases) involved in the resistant response in plant-nematode interaction.. Of particular interest is elucidation of the role played by nematode oesophageal secretions in modifying and regulating the function, metabolism, and phenotype cells to form sophisticated feeding sites in their hosts; cytochemical and immunocytochemical studies of reorganization of cytoskeleton elements (actin, tubulin) during compatible response in plant-nematode interaction.
Actually, my reaserch is focused on use of the chemical (BTH) and physical (ozone) elicitors
on susceptible tomato cultivar to increase plant defence to nematodes. The effects of BTH or ozone on tomato-nematode interacion and production of ROS and activity of some enzymes related to plant defense mechanisms are being investigated.
