[The evolution of plant disease resistance gene].
The evolution of plant disease resistance genes has shaped in some kinds of common forms. The duplication of plant progenitor disease resistance gene creates disease resistance gene loci. The intragenic and extragenic recombination results in variation. Recombination also is involved in generation novel resistance specificities. In addition, the leucine-rich repeats (LRRs) involved in recognitional specificity are subject to adaptive selection. Insertion of transposable elements into several resistance gene loci result in further evolution of resistance genes. With the evolution of plant disease resistance genes, the R genes (resistance genes)-mediated response shows diversification which represents different stages in the oscillating evolution between plants and their pathogens.
