We checked the resistance phenotypes of these 34 cwm lines and their wild-type counterparts (Col-0, Ws, or La-er) upon infection with Pc, Rp, or Hpa either by evaluating plants macroscopic disease symptoms caused by Rp and Pc and assigning Disease Rating values (DR) or by determining Hpa sporangiophores formation on plant leaves and conidiospore production by these sporangiophores per plant fresh weight. This evidence concerns the gene BLOC1S3 and infection.
