Abstract Lignin, flavonoids, melatonin, and stilbenes are plant specialized metabolites with diverse physiological biological functions, supporting growth conferring stress resistance. Their biosynthesis requires O-methylations catalyzed by 5-hydroxyconiferaldehyde O-methyltransferase (CAldOMT; also called caffeic acid O-methyltransferase, COMT). CAldOMT was first known for its roles in syringyl (S) lignin angiosperm cell walls later found to be multifunctional. This enzyme catalyzes flavonoid, stilbene biosynthetic pathways. Phylogenetic analysis indicated the convergent evolution of enzymes OMT activities towards monolignol pathway intermediates some gymnosperm species that lack S-lignin Selaginella moellendorffii, a lycophyte which produces S-lignin. Furthermore, neofunctionalization CAldOMTs occurred repeatedly during evolution, generating unique O-methyltransferases (OMTs) novel catalytic and/or accepting substrates, including lignans, 1,2,3-trihydroxybenzene, phenylpropenes. review summarizes multiple aspects their related proteins metabolism discusses molecular mechanism, biorefineries, agriculture, synthetic biology.

Gummy stem blight (GSB), a widespread disease causing great loss to cucurbit production, has become major threat melon cultivation. However, the melon-GSB interaction remains largely unknown. Here, full-length transcriptome and widely targeted metabolome were used investigate defence responses of resistant (PI511089) susceptible (Payzawat) accessions GSB pathogen infection at 24 h. The biosynthesis secondary metabolites MAPK signalling pathway specifically enriched for differentially expressed genes in PI511890, while carbohydrate metabolism amino acid Payzawat. More than 1000 novel identified was them PI511890. There 11 793 alternative splicing events involving response GSB. Totally, 910 Payzawat flavonoids dominant metabolites. Integrated analysis showed eriodictyol oxalic potential marker resistance melon. Moreover, posttranscription regulation involved infection. These results not only improve our understanding on between GSB, but also facilitate genetic improvement with resistance.

Botrytis cinerea, the causative agent of gray mold disease (GMD), invades plants to obtain nutrients and disseminates through airborne conidia in nature. Bacillus amyloliquefaciens strain GD4a, a beneficial bacterium isolated from switchgrass, shows great potential managing GMD plants. However, precise mechanism by which GD4a confers benefits remains elusive. In this study, an A. thaliana-B. cinerea-B. multiple-scale interaction model was used explore how bacteria play essential roles plant growth promotion, pathogen suppression, immunity boosting. Arabidopsis Col-0 wild-type served as testing ground assess GD4a’s efficacy. Additionally, bacterial enzyme activity targeted metabolite tests were conducted validate for enhancing suppressing pathogens diseases. subjected co-incubation with various bacterial, fungal, oomycete evaluate its antagonistic effectiveness vitro. vivo inoculation assays also carried out investigate role regulating host immunity.
