A Review of the Mechanisms of Action of the Herbal Medicine, STW 5‐II, Underlying Its Efficacy in Disorders of Gut–Brain Interaction

open access: yesNeurogastroenterology &Motility, EarlyView.
The pathophysiology of functional dyspepsia and irritable bowel syndrome includes altered motility, secretion, sensitivity to sensory signals, impaired epithelial barrier function, inflammation, and gut dysbiosis. The phytomedicine, STW 5‐II, represents a multi‐targeted approach, addressing these pathophysiologies.

Direct synthesis, characterization, in vitro and in silico studies of simple chalcones as potential antimicrobial and antileishmanial agents

open access: yesRoyal Society Open Science
Chalcone represents a vital biosynthetic scaffold owing to its numerous therapeutic effects. The present study was intended to synthesize 17 chalcone derivatives (3a–q) by direct coupling of substituted acetophenones and benzaldehyde.

The genetic basis of replicated bullseye pattern reduction across the Hibiscus trionum complex

open access: yesNew Phytologist, EarlyView.
Summary Colorful petal patterns fulfill important functions and constitute excellent systems to illuminate the evolutionary processes that generate morphological diversity or instead support the repetitive emergence of similar forms. Here, we combined phylogenomic approaches, genetic manipulations, molecular techniques, and bee behavioral experiments ...

Role of LEAFLESS, an AP2/ERF family transcription factor, in the regulation of trichome specialized metabolism

open access: yesNew Phytologist, EarlyView.
Summary Acylsugars, specialized metabolites produced by trichomes of many solanaceous species, provide protection against biotic and abiotic stresses. Many acylsugar metabolic enzymes have been identified; however, regulatory factors remain unknown.

Modulation of lignin and anthocyanin homeostasis by GTP cyclohydrolase1 in maize

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Maize is a key biomass resource with wide agricultural applications. Anthocyanins, potent antioxidants, offer health benefits like reducing oxidative stress. The biosynthesis of anthocyanins competes with that of lignin for shared metabolic precursors, which can lead to trade‐offs in plant growth and feed quality.

ERF100 regulated by ERF28 and NOR controls pectate lyase 7, modulating fig (Ficus carica L.) fruit softening

open access: yesPlant Biotechnology Journal, EarlyView.
Summary The mechanism regulating fruit textural changes has not been fully elucidated. Transcription factor FcERF100 showed rapid transcription repression during drastic texture loss in fig (Ficus carica L.) fruit ripening. Transient overexpression of FcERF100 delayed fig fruit softening and significantly decreased the transcript abundance of a key ...

A model for the adaptation of Euryale ferox leaves to aquatic environments through EfCGT1‐controlled flavonoid C‐glycoside‐specific accumulation in epidermis cells

open access: yesPlant Biotechnology Journal, EarlyView.
Summary With changes in complex environments, plants, especially their leaves, are constantly adapting. Aquatic plants face more diverse and harsh survival situations. However, their adaptive mechanisms are largely unknown. Euryale ferox is a floating leaf aquatic plant characterized by large and rapidly expanding leaves that serve as a model for ...
