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.

Proposed model of TAC1‐mediated leaf angle regulation in tobacco. ABSTRACT Plant architecture is key to crop yield, with leaf angle being critical for high‐density cultivation. Although TAC1 represents a promising regulator of leaf angle for breeding, its molecular mechanism remains poorly understood, particularly at single‐nucleus resolution. Here, we

Synthetic Derivatives of Natural Alkaloid Harmine
The indole alkaloid harmine was extracted from underground part of Peganum harmala L. With the purpose of obtaining the new biological active derivatives on base of alkaloid harmine the chemical modification was carried out.

ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Excelsinidine, A Quaternary Alkaloid from
A chemical investigation of Aspidosperma excelsum yielded excelsinidine ( 1 ), a quaternary indole alkaloid possessing an unusual 1-azoniatricyclo[4.3.3.0]undecane moiety, along with the known compound aspidodasycarpine ( 2 ).

The Enhancement of Catharanthine Content in Catharanthus roseus Callus Culture Treated with Naphtalene Acetic Acid [PDF]
The research aim was to examine the enhancement of catharanthine content in Catharanthus roseus callus culture added with different concentration of Naphtalene Acetic Acid (NAA). NAA treatment produced callus that formed hairy roots. Fresh and dry weight

Advances in organic UV filters for sunscreens over the past decade
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.
