PR10/Bet v1‐like Proteins as Novel Contributors to Plant Biochemical Diversity

Abstract: Pathogenesis‐related (PR) proteins constitute a broad class of plant proteins with analogues found throughout nature from bacteria to higher eukaryotes. PR proteins were first noted in plants as part of the hypersensitive response, but have since been assigned an array of biological roles. The PR10/Bet v1‐like proteins are a subset of PR proteins characterized by an ability to bind a wide range of lipophilic ligands, uniquely positioning them as contributors to specialized biosynthetic pathways. PR10/Bet v1‐li… Show more

“…In the ML tree inferred from three chloroplast (cp) markers and nuclear ITS ( Xiang et al, 2017 ), D. lobatipetalum was basal to D. fargesii , possibly because not enough DNA markers were used, and cp DNA and nuclear ITS have special and distinct ways of evolution. (S)-norcoclaurine synthase (NCS), belonging to the Pathogenesis-related class (PR)10/Bet v1-like protein family ( Morris et al, 2021 ), catalyzes the condensation of dopamine and 4-hydroxyphenylacetaldehyde to form (S)-norcoclaurine, which is the first step in the BIA biosynthesis. The NCS genes of some Ranunculales species have been functionally characterized ( Lee & Facchini, 2010 ; Marques et al, 2014 ).…”

“…Thus, a mechanistic understanding of PR10 function, as binding proteins for generally hydrophobic ligands, has replaced the initial categorization of being strictly linked to the pathogenesis response. PR10 proteins interact with biological ligands, including phytohormones, proteins, fatty acids, amino acids, phenolics, and several classes of alkaloids (Morris et al., 2020). PR10s are known to bind a wide range of phytohormones, including cytokinins (e.g., zeatin), brassinosteroids (e.g., brassinolide), auxins (e.g., melatonin), gibberellic acid, and abscisic acid (ABA).…”

“…These include the production of antimicrobial peptides, particularly pathogenesis-related proteins (PR proteins). PR proteins were first noted in plants as part of the hypersensitive response, but have since been assigned an array of biological roles [40]. PR proteins are a type of stress-responsive protein whose expression can be induced by pathogen invasion [41].…”
