High-affinity copper transport and Snq2 export permease of saccharomyces cerevisiae modulate cytotoxicity of PR-10 from Theobroma cacao.

A pathogenesis-related (PR) protein from Theobroma cacao (TcPR-10) was identified from a cacao-Moniliophthora perniciosa interaction cDNA library. Nucleotide and amino acid sequences showed homology with other PR-10 proteins having P loop motif and Betv1 domain. Recombinant TcPR-10 showed in vitro and in vivo ribonuclease activity, and antifungal activity against the basidiomycete cacao pathogen M.
