Putative Genes of Pathogenesis-Related Proteins and Coronatine-Insensitive Protein 1 in Ribes spp.


ABSTRACT: In response to pathogen attacks, plants activate a complex of defense mechanisms including an accumulation of the endogenous signaling compounds salicylic acid and jasmonic acid. The activity of pathogenesis-related genes (PRs) and coronatine-insensitive 1 (COI1) in defense-response pathways are established in plants. The aim of this study was to identify homologs of the PRs and COI1 in blackcurrants. Primers with degenerate nucleotides were designed based on the most conservative parts of PR1 and COI1 genes from other plants and applied for amplification of specific fragments of PRs and COI1 in Ribes spp. Seven heterogeneous sequences of PR with a diversity of 66.0-98.3% at nucleic acid level were found. The phylogenetic analysis revealed the dependence of R. nigrum PR homologs on the PR1 and PR6 families. Four heterogeneous sequences of R. nigrum COI1 with an identity of 95.9-98.8% at nucleic acid level were isolated. Specific primers for newly detected genes' homologs were designed in this study and could be useful for evaluating the defense response to pathogen attacks in blackcurrants.

In response to pathogen attacks, plants activate a complex of defense mechanisms including an accumulation of the endogenous signaling compounds salicylic acid and jasmonic acid. The activity of <i>pathogenesis-related</i> genes (<i>PR</i>s) and <i>coronatine-insensitive 1</i> (<i>COI1</i>) in defense-response pathways are established in plants. The aim of this study was to identify homologs of the <i>PR</i>s and <i>COI1</i> in blackcurrants. Primers with degenerate nucleotides were designed bas  ...[more]
