Catharanthus

open access: yes, 2021
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

open access: yesAngewandte Chemie, Volume 138, Issue 20, 11 May 2026.
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.

Chitosan‐induced modulation of secondary metabolism and stress tolerance in Salvia rosmarinus under combined drought and heat stress

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
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

open access: yesPediatric Investigation, EarlyView.
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.

The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

open access: yesPlant Biotechnology Journal, EarlyView.
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 ...

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

open access: yesPlant Biotechnology Journal, EarlyView.
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

OsRALF26 Serves as an Endogenous Signal Recognised by XA21 to Promote Robust and Distal Resistance in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
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.

Analysis of BpbHLH Gene Family Responsive to MeJA Signalling in Betula platyphylla Suk. and Functional Mechanisms of BpbHLH42/44 in Genetic Improvement and Triterpenoid Biosynthesis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The basic helix–loop–helix (bHLH) transcription factor family regulates plant secondary metabolism, development and stress responses. Although triterpenoids such as betulinic acid (BA), betulin (BT) and oleanolic acid (OA) from Betula platyphylla Suk.

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

open access: yesPlant Biotechnology Journal, EarlyView.
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.
