2.8. Molecular modeling of Catharanthus and Camptotheca P450s Molecular models for Catharanthus CYP 72A1 and Camptotheca CYP72A564 and CYP72A565, constructed according to published procedures (Rupasinghe and Schuler, 2006), indicated that the backbones of these three proteins overlay well (RMSD less than 2.0 Å, green, Fig.

Discovery of a Plant Pictet–Spenglerase With R‐Stereoselectivity
Strictosidine synthases (STRs) are plant Pictet–Spenglerases catalyzing the coupling of a secoiridoid with tryptamine. All previously characterized strictosidine synthases are strictly S‐selective. Here, we report the discovery of Epi‐STR, an R‐selective STR ortholog from the medicinal plant Pogonopus speciosus.

Abstract BACKGROUND Abiotic stresses, particularly drought and elevated temperatures, negatively affect plant physiological and metabolic processes. This study investigated the effects of drought, heat, and combined stress on Salvia rosmarinus (rosemary), and evaluated foliar‐applied chitosan as a biostimulant.

Kaposiform hemangioendothelioma: Diagnosis and treatment
Vascular endothelial growth factor‐C (VEGF‐C)/vascular endothelial growth factor receptor‐3 (VEGFR‐3) and angiopoietin‐2 (Ang‐2)/tyrosine kinase with immunoglobulin‐like and EGF‐like domain 2 (TIE2) signaling pathways play an important role in lymphangiogenesis.

ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...

BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

ABSTRACT Plant immune receptors detect both microbe‐derived and endogenous signals to activate defences. XA21, a rice immune receptor, confers strong race‐specific resistance to a subset of Xanthomonas oryzae pv. oryzae (Xoo) strains by recognising the microbial sulphated peptide RaxX.

ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.
