The role of phytohormones ethylene and auxin in plant-nematode interactions

The role of phytohormones ethylene and auxin in plant-nematode interactions The phytohormones ethylene and auxin regulate many important processes in plants, including cell differentiation, cell expansion, and responses to abiotic stresses. These hormones also play important roles in many plant-pathogen interactions, including regulation of plant defense responses and symptom development. Sedentary plant-parasitic nematodes, which require the formation of a complex feeding site within the host root, are among the world’s most destructive plant pathogens. Nematode-induced feeding sites show dramatic changes in host cell morphology and gene expression. These changes are likely mediated, at least in part, by phytohormones. In the present review, current knowledge of the roles of ethylene and auxin will be explored in two main areas: the specific role of phytohormones in mediating feeding site development by plant-parasitic nematodes and the general role of phytohormones in affecting the ability of parasitic nematodes to cause disease. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

The phytohormones ethylene and auxin regulate many important processes in plants, including cell differentiation, cell expansion, and responses to abiotic stresses. These hormones also play important roles in many plant-pathogen interactions, including regulation of plant defense responses and symptom development. Sedentary plant-parasitic nematodes, which require the formation of a complex feeding site within the host root, are among the world’s most destructive plant pathogens. Nematode-induced feeding sites show dramatic changes in host cell morphology and gene expression. These changes are likely mediated, at least in part, by phytohormones. In the present review, current knowledge of the roles of ethylene and auxin will be explored in two main areas: the specific role of phytohormones in mediating feeding site development by plant-parasitic nematodes and the general role of phytohormones in affecting the ability of parasitic nematodes to cause disease.
