| molecular cloning and characterization of the avr-pia locus from a japanese field isolate of magnaporthe oryzae. | in order to clone and analyse the avirulence gene avr-pia from japanese field isolates of magnaporthe oryzae, a mutant of the m. oryzae strain ina168 was isolated. this mutant, which was named ina168m95-1, gained virulence towards the rice cultivar aichi-asahi, which contains the resistance gene pia. a dna fragment (named pm01) that was deleted in the mutant and that co-segregated with avirulence towards aichi-asahi was isolated. three cosmid clones that included the regions that flanked pm01 we ... | 2009 | 19400839 |
| establishment of a new cross of the rice blast fungus derived from japanese differential strain ina168 and hermaphroditic rice pathogen guy11. | mating experiments between magnaporthe grisea japanese rice pathogens and guy11, a hermaphroditic fertile rice pathogen, were done aimed at identification of avirulence genes. a cross named cross 2107 with thirty-six random progenies was obtained. segregation analyses of genetic markers found that the cross was less suitable for genetic analysis. backcrosses with cross 2107 progenies and guy11 were done and another cross named cross 5307 with sixty-five progenies was obtained. a locus controllin ... | 2001 | 11515527 |
