Abstract

Three distinct basic 14-kD proteins, P14a, P14b, and P14c, were isolated from tomato (Lycopersicon esculentum Mill. cv Baby) leaves infected with Phytophthora infestans. They exhibited antifungal activity against P. infestans both in vitro (inhibition of zoospore germination) and in vivo with a tomato leaf disc assay (decrease in infected leaf surface). Serological cross-reactions and amino acid sequence comparisonsshowed that the three proteins are members of the PR-1 group of pathogenesis-related (PR) proteins. P14a and P14b showed high similarity toa previously characterized P14, whereas P14c was found to be very similar to a putative basic-type PR-1 from tobacco predicted from isolated DNA clones. This protein, named PR-1g, was purified from virus-infected tobacco (Nicotiana tabacum Samsun NN) leaves and characterized by amino acid microsequencing, along with the well-known acidic tobacco PR-la, PR-1b, and PR-1c. The various tomato and tobacco PR-1 proteins were compared for their biological activity and found to display differential fungicidal activity against P. infestans in both the in vitro and in vivo assays, the most efficient being the newly characterized tomato P14c and tobacco PR-1g.
