From model to crop plant-pathogen interactions:cloning of the first resistance gene to Leptosphaeria maculans in Brassica napus
Résumé
Numerous plant disease resistance (R) genes to viruses, bacteria,oomycetes, fungi and nematodes have been cloned over the last fewyears, with an overrepresentation of genes of the model species Arabidopsis thaliana (Gururani et al., 2012). The vast majority of these encode cytoplasmic proteins of the nucleotide bindingleucine rich repeat (NB-LRR) superfamily, and nearly all R genes operating against bacteria and oomycetes are cytoplasmic NB-LRR (Gururani et al., 2012). By contrast, R genes towards fungal pathogens are much more varied possibly because of the extreme diversity of fungal phytopathogens and of their modes of life within the plant tissues.
