Abstract: | The review deals with the mechanisms of innate immunity in plants focusing on families of pattern-recognition receptors and incorporates recent data on complete sequencing of several plant genomes. Plant immune response involves several families of receptors, both membrane-bound and cytoplasmic ones, containing conservative leucine-rich repeats. The lack of adaptive immunity and the associated rearrangements in the immune receptor genes in plants is partly counterbalanced by genetically encoded mechanisms of specific immunity to particular pathogens. There is a certain similarity between intracellular signal transduction and effector mechanisms in plant and animal innate immune systems, although the latter are considerably more complex. |
