Outline of Final Research Achievements |
Lolium isolate TP2 (pathogenic on ryegrass) and Avena isolate Br58 (pathogenic on oat) of P. oryzae gained virulence on common wheat through disruption of their avirulence gene(s), PWT3 and PWT3/PWT4, respectively, suggesting that loss of function of these avirulence genes leads to the emergence of the wheat blast fungus (Triticum isolates). The current Triticum isolates had mutations in PWT3 - insertion of transposable elements or nucleotide substitutions. The avirulence of Eleusine isolate MZ5-1-6 (pathogenic on finger millet) on common wheat was controlled by five genes. One of them was cloned and designated as PWT6.
