Phytoalexins and their Significant Role in the Plant Resistance Management

Jolly Sen

Abstract


Phytoalexins are antibiotic compounds synthesized in an infected plant in reply to infection. Nematodes are capable of eliciting phytoalexins in resistant plants. Phytoalexins are antibiotic compounds synthesized in an infected plant in response to infection. Nematodes are capable of eliciting phytoalexins in resistant plants. Resistant lima bean (Phaseolus lunatus) infected by Pratylenchus penetrans produces the phytoalexin coumestrol; soybean (Glycine max) infected by Meloidogyne incognita produces glyceollin; cotton (Gossypium hirsuturn) infected by M. incognitaproduces terpenoid aldehydes. Keywords: host plant resistance, phytoalexins, gossypol, coumarins, disease resistance, physiology
