Molecular aspects of phytoimmunity

Studies on mechanisms of perception and transduction of elicitor signals to plant cell genome are reviewed Participation of different signal systems ( including cAMP-, MAPK-, Ca2+-lipoxygenase-, superoxide synthase-, NO-syntha se systems) in forming of defence response to pathogens is discussed. Atten tion is primarily paid to interrelations between mycoplasms and plants.
