Synthesis of defensive pathogenesis-related (PR) proteins in plants is induced by biotic and abiotic stress. The family of plant PR proteins is divided into 17 classes differing in their structural and functional properties. Two representative classes of plant PR protein family are Bet v 1 (PR-...
These proteins include: 1) structural proteins that are incorporated into the extracellular matrix and participate in the confinement of the pathogen; 2) enzymes of secondary metabolism, for instance those of the biosynthesis of plant antibiotics; 3) pathogenesis-related (PR) proteins which represent ...

‘high-sugar resistance’ concept. For instance, application of sugar to various plant tissues, or provoking sugar accumulation intransgenic plants, can activate genes encoding antimicrobial pathogenesis-related (PR) proteins[114–116]. Similarly,transgenicpotato tubers with reduced activity of theplastid...
Pathogenesis-related proteins belonging to group 10 (PR10) are elevated in response to biotic and abiotic stresses in plants. Previously, we have shown a drastic salinity-induced increase in the levels of ABR17, a member of the PR10 family, in pea. Furth
In response to effectors, plants have evolved intracellular receptors to recognize effectors and activate effector-triggered immunity (ETI). ETI involves initiation of MAPK cascades and expression of pathogenesis-related proteins (PRs) like PTI74. Both pathways also trigger systemic acquired resistance (...
Plant NPR1 (Non-Expressor of PR (Pathogenesis-Related 1)) gene, encoded protein and applications thereof本发明涉及植物的一个NPR1基因,其特征在于具有下述核苷酸序列:a)序列表中的Seq ID No.1的DNA序列;b)在高严谨条件下与序列表中Seq ID No.1限定的DNA序列杂交的核苷酸序列,所述高严谨条件为在0.1×SSPE...
Brassinosteroid responsive genes were identified by filtering HMMER hits for ‘bHLH-MYC_N domain’ and ‘14–3-3’ to identify brassinazole-resistant1 and 14–3-3 proteins respectively. Pathogenesis-related genes were considered true PR genes if they were i) identified as orthologous using ‘...
Pathogenesis-related 10 (PR-10) is a group of small intracellular proteins that is one of 17 subclasses of pathogenesis-related proteins in plants. The PR-10 proteins have been studied extensively and are well-recognized for their contribution to host defense against phytopathogens in several plant...
Pathogenesis-related (PR) proteins are plant proteins that are induced in response to pathogen attack. However, several studies suggest that these proteins can also be induced by a variety of abiotic stresses, such as wounding and exposure to chemicals or heavy metals [26, 41–43]. The PR-4...
