“…Resistance responses can be divided into a series of inter-related stages (Dangl and Jones, 2001;Veronese et al, 2003). Recognition of pathogen is the earliest step by the host plant that frequently involves interaction between R genes and pathogen avirulence genes that encode specific elicitors.…”

“…An incompatible interaction results in the triggering of the defense responses through signaling pathways, including nitric oxide, reactive oxygen intermediates, jasmonic acid (JA), salicylic acid (SA), and ethylene. Signal transduction pathways activate a broad series of defense responses that remove the pathogen, such as hypersensitive response (HR); upregulation of phenylalanine ammonium lyase, a key enzyme in plant defense; deposition of cell wall reinforcing materials; and synthesis of a wide range of antimicrobial compounds, including pathogenesis-related (PR) proteins and phytoalexins (Veronese et al, 2003).…”

ABSTRACT. Powdery mildew, caused by Blumeria graminis f. sp tritici (Bgt) is one of the devastating diseases of wheat and causes yield losses in temperate wheat growing regions. A wheat line, N0308 with resistance to powdery mildew was used in this study. A suppression subtractive hybridization cDNA library was constructed from the wheat leaves inoculated by Bgt at the two-leaf stage. The differentially expressed genes in response to Bgt infection in wheat were identified, and a total of 175 positive clones from the library were sequenced, and 90 expressed sequence tags (ESTs) were subjected to clustering, BLAST alignment, functional annotation, and classification into different categories. By comparing the EST sequences among the SSH-cDNA libraries, we analyzed gene expression patterns of 7 ESTs associated with the resistance reaction of powdery mildew by using semi-quantitative reverse transcription-polymerase chain reaction. The expression of 5 genes (sulfatase, pathogenesis-related protein 17, betacarbonic anhydrase 2, thioredoxin h-like protein, and coronatineinsensitive) transcripts was induced, and the transcript levels of these genes were the highest at 72 h after Bgt infection, while those of 2 genes (violaxanthin de-epoxidase and gag-pol-polyprotein) were the highest level at 12 and 18 h post-infection, respectively. These findings suggest that these genes are induced at an early stage of infection and are transcriptionally activated for the host defense response.

“…PRs activity is often specific towards a particular microbial species, i.e., recognizing specific structures on the microbial cell surface before damage to the membrane occurs 353 . A growing number of reports confirm the ability of PRs to bind particular components of microbial cell walls or membranes, thereby supporting the hypothesis of target specificity.…”

The mature barley seed proteome is dominated by proteins involved in stress responses, including the Pathogenesis-Related proteins (PRs). PRs are currently classified into 17 families. The biochemistry of the PRs families, whose members are constitutively present in barley seed, is surveyed in this paper. These proteins are assumed to protect dormant and germinating seeds against pathogenic microorganisms and pests. The current knowledge on PRs structural and functional properties is summarized in an attempt to illustrate their importance in barley seed innate resistance. At the same time, a platform to understand PRs technological function in cereal foods and in beverage processing and quality is provided.

A Review: The Role of Barley Seed Pathogenesis-Related Proteins (PRs) in Beer Production

Pathogenesis-related proteins (PRs) are involved in the protection of dormant and germinating cereal seeds against pathogenic microorganisms and pests. Moreover, barley grain PRs have considerable technological importance in the brewing of beer. The compact structure of PRs allows them to survive the hostile conditions of the extracellular compartments, where they are usually localized, and enables the endurance of certain classes of PRs during the harsh conditions of the technological steps of beer production. Beer proteome maps reveal a dominant presence of PRs and facilitate association between particular proteins and specific beer quality traits. Current knowledge on the influence of PRs on the various aspects of beer quality has been summarized in this review.
