Phenotypical, cytological and molecular responses of rice to the fungus Magnaporthe grisea were studied using rice cultivars and lesion mimic plants. The cultivar Katy was susceptible to several virulent M. grisea isolates, and a Sekiguchi like-lesion mimic mutant of Katy (LmmKaty) showed enhanced resistance to these isolates. Lesion mimic phenotype of LmmKaty was rapidly induced by virulent M. grisea...
The Pi-ta gene from indica introgressed into japonica rice has been used to control the blast disease caused by the fungal pathogen Magnaporthe grisea (Herbert) Barr. (anamorph Pyricularia oryzae Cav.) worldwide. A single nucleotide length polymorphism (SNLP) was identified at the intron region of the Pi-ta gene to develop a codominant Pi-ta gene marker suitable for genotyping with an automated machine...
