Sexual reproduction may be cryptic or facultative in fungi and therefore difficult to detect. Magnaporthe oryzae, which causes blast, the most damaging fungal disease of rice, is thought to originate from southeast Asia. It reproduces asexually in al

We developed nine new microsatellite markers for rice blast (Magnaporthe grisea) population studies. These markers were used in addition to nine microsatellite markers previously developed by our group for mapping purpose. Altogether, the 18 markers

International audience; Our view of genes involved in rice disease resistance is far from complete. Here we used a gene-for-gene relationship corresponding to the interaction between atypical avirulence gene ACE1 from Magnaporthe grisea and rice resi

Isolates of the rice blast fungus Magnaporthe grisea that carry the gene encoding Avirulence Conferring Enzyme1 (ACE1) are specifically recognized by rice (Oryza sativa) cultivars carrying the resistance gene Pi33. This recognition enables resistant

The sequences of the coat protein gene of a representative sample of 40 isolates of Rice yellow mottle virus (RYMV) from 11 African countries were analysed. The overall level of nucleotide diversity was high ( ∼14 %). Great geographical distances b

Using a genomic clone encoding a rice lipid transfer protein, LTP1, we analysed the activity of the 5′ region of the Ltp1 gene in transgenic rice (Oryza sativaL.) during plant development and under pathogen attack. The −1176/+13, −556/+13 and

In a cross between two isolates of the rice blast fungus Magnaporthe grisea , a spontaneous mutant was identified which was non-pathogenic on rice and did not differentiate appressoria on hydrophobic surfaces. The mutant was also non-pathogenic on ri

We characterized two spontaneous developmental mutants of the heterothallic Ascomycete Magnaporthe grisea. The first mutant, isolated from finger millet isolate OG2, sporulated abundantly when grown on artificial medium. Compared to wild type, the sp

The genetic variability among 41 isolates of the blast pathogen (Magnaporthe grisea) from five European rice growing countries was studied. The genealogy of the isolates was investigated by DNA fingerprinting and the results compared to the degree of
