Pathogenesis-related (PR) proteins and antimicrobial peptides (AMPs) are a group of diverse molecules that are
induced by phytopathogens as well as defense related signaling molecules. They are the key components of plant
innate immune system especially systemic acquired resistance (SAR), and are widely used as diagnostic molecular
markers of defense signaling pathways. Although, PR proteins and peptides have been isolated much before
but their biological function remains largely enigmatic despite the availability of new scientific tools. The earlier
studies have demonstrated that PR genes provide enhanced resistance against both biotic and abiotic stresses,
which make them one of the most promising candidates for developing multiple stress tolerant crop varieties. In
this regard, plant genetic engineering technology is widely accepted as one of the most fascinating approach to
develop the disease resistant transgenic crops using different antimicrobial genes like PR genes. Overexpression
of PR genes (chitinase, glucanase, thaumatin, defensin and thionin) individually or in combination have greatly
uplifted the level of defense response in plants against a wide range of pathogens. However, the detailed
knowledge of signaling pathways that regulates the expression of these versatile proteins is critical for improving
crop plants to multiple stresses, which is the future theme of plant stress biology. Hence, this review provides an overall overview on the PR proteins like their classification, role in multiple stresses (biotic and abiotic) as well as in various plant defense signaling cascades. We also highlight the success and snags of transgenic plants expressing PR proteins and peptides.
