Genome-wide analysis of pathogenesis-related protein-1 (PR-1) genes from Qingke (Hordeum vulgare L. var. nudum) reveals their roles in stress responses.

ABSTRACT: Proteins that are pathogenesis-related 1 (PR-1) can accumulate to high levels when plants employ defenses, being major participants in processes critical for stress responses as well as development of many species. Yet we still lack information concerning PR-1 family members in Qingke plants (Hordeum vulgare L. var. nudum). In this work, we distinguished 20 PR-1s from the Qingke genome whose encoded proteins often featured at the N-terminus a signal peptide; all 20 PR-1s were predicted to localize either periplasmically or extracellularly. The CAP domain was confirmed as being highly conserved in all these PR-1s. Phylogeny-based inference revealed that PR-1 proteins clustered into four major clades, with the majority of Qingke PR-1s distributed in clade I (17 ou
