Abstract
The pathogenesis-related protein 1 (PR-1) gene family play important roles in the plant metabolism in response to biotic and abiotic stresses. The present study aimed genome-wide identification and bioinformatics analyses of PR-1 genes in tomato (Solanum lycopersicum L.). The analyses resulted in the identification of 13 novel SlPR-1 genes, each of which produce a protein belonging to the CAP superfamily (PF00188). The KEGG annotation analyses revealed that the SlPR-1 proteins functioned in the environmental information processing (09130). The expression patterns of the PR-1 genes and some stress-related physiological parameters were investigated in Fusarium oxysporum sensitive and tolerant tomato varieties under drought stress. The drought stress leaded upregulation of all SlPR-1 genes, reaching up to 50 folds. The results indicate that the SlPR-1 genes play active roles in response to drought. This is the first study exhibiting the expression profiles of SlPR-1 genes under an abiotic stress, drought, in tomato.
