Research Abstract |
Leaf mold of tomato is caused by the biotrophic fungus Cladosporium fulvum which complies with the gene-for-gene system. We sequenced avirulence (Avr) genes in 123 strains collected in Japan to get information about the molecular basis of adaptation to the different Cf genes. The Avr genes of these strains contain unique mutations causing adaptation to Cf genes including (i) frameshift mutations, (ii) transposon insertions in Avr2, (iii) point mutations in Avr4 and Avr4E, and (iv) deletions of Avr4E or Avr9. Proteomics analysis of the apoplastic fluid and RNAseq data were employed to collect the candidates of new effector gene. Among them we identified Avr5 that is conferred by the tomato resistance gene Cf-5 and is located on 1.8 Mb small chromosome.
