Adaptive Genomic Divergence Across Altitudes in Capsella bursa‐pastoris

Biological Diversity, EarlyView.
Genomic divergence was observed between high‐altitude and low‐altitude populations of Capsella bursa‐pastoris in China, consistent with an important role of ecological factors. Candidate adaptive loci associated with enhanced energy metabolism, photoprotection, and growth plasticity under altitudinal stress were identified.

Characterization of a novel allele encoding pheophorbide a oxygenase in rice [PDF]

Plant Signaling & Behavior, 2020
We identified a rapid cell death 2 (rcd2) mutant from an indica cultivar Zhongjian100 mutant bank. The red-brown lesions appeared firstly on young seedling leaves, then gradually merged and the leaves completely withered at the late tillering stage. rcd2 displayed apparent cell death at/around the lesions, accumulation of superoxide anion (O2−) and ...

Optimising the Eco‐Friendly Extraction of Carotenoids From Gac Fruit: A Sustainable Solution for Natural Red Food Colourants

Food Chemistry International, EarlyView.
Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...

Viruses in the sediments around the trenches harbor diverse survival mechanisms

iMetaOmics, EarlyView.
Deep‐sea trenches are the deepest and most isolated environments in the global ocean but the diversity and adaptation of the viral communities remain poorly characterized. In this study, 5563 viral operational taxonomic units (vOTUs) were identified from sediments of the Yap Trench and Western Caroline Basin.

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, EarlyView.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

ISOLATION AND STRUCTURE DETERMINE OF SOME COMPOUNDS FROM THE METHANOL EXTRACT OF Enhalus acoroides COLLECTED IN VIETNAM

Tạp chí Khoa học
Three compounds were isolated from the methanol extract of the species Enhalus acoroides using a combination of several chromatographic methods. The structural elucidations of those compounds were analysed using ESI-MS and NMR.

Desiccation tolerance mechanisms in the green lineage and beyond

New Phytologist, EarlyView.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...

Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...
