Taxoids from Taxus chinensis

open access: yes, 2016
Two new taxoids, 13,15-epoxy-13-epi-taxayunnasin A (1) and taxchinin N (2), were isolated from the leaves and stems of Taxus chinensis. Compound 2 is the first taxoid to be reported with an α,β-unsaturated lactone at C-4, C-5, C-20, and C-2.

Importance of plant and bird traits on the seed removal pattern of endangered trees across different forest patches in southeast China

open access: yesEcological Processes, 2020
Seed removal by birds has been recognized as an important part of seed dispersal process in patchy forest areas; however, few studies have focused on the contribution of both plant and bird traits to seed removal.

The RcDREB1E‐RcMYB28 module improves drought tolerance in Rosa chinensis via RcLAR/RcCORA1‐mediated proanthocyanidin biosynthesis and stress responses

open access: yesThe Plant Journal, Volume 128, Issue 1, October 2026.
SUMMARY Drought is widely recognized as one of the most severe abiotic stresses limiting plant growth and productivity. Proanthocyanidins (PAs), as key functional secondary metabolites, are central to enhancing plant tolerance to abiotic stresses. Nevertheless, the specific mechanisms underlying PA‐mediated drought resistance in rose remain largely ...

Interactive Effects of Climate and Land Use Change on Taxus Species: An Integrated Modelling Framework for Identifying Long‐Term Refugia

open access: yesDiversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aim Biodiversity is fundamental to maintaining ecosystem function and stability, while climate change (CC) and land‐use/land‐cover change (LUCC) jointly threaten the survival of endangered tree species. Currently, the individual and combined effects of these two factors on species distribution remain unclear, and their interaction mechanisms ...

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

open access: yesFood Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...
