Pathogenesis-Related Proteins

  • P. Parvatha Reddy


Pathogenesis-related proteins (PRs) (initially named ‘b’ proteins) have focused an increasing research interest in view of their possible involvement in plant resistance to pathogens. This assumption flowed from initial findings that these proteins are commonly induced in resistant plants, expressing a hypersensitive necrotic response (HR) to pathogens of viral, fungal and bacterial origin. PRs have been defined as ‘proteins encoded by the host plant but induced only in pathological or related situations’, the latter implying situations of non-pathogenic origin. This research encouraged the application of PR genes in gene-engineering technologies for crop improvement.
