Deciphering Transcriptional Dynamics of Angelica sinensis Seed Development to Define the Optimal Harvesting Stage

The root of Angelica sinensis (Oliv.) Diels is a traditional Chinese medicine. While physiological and biochemical approaches to improve seed quality during maturation have been explored, the regulatory mechanism governing the optimal harvesting stage remains uncovered. Here, tra...

Spatiotemporal characteristics of vegetation responses to compound drought and heatwave events in Central Asia

With climate warming intensifying, compound drought and heatwave (CDHW) events have become more frequent and intense in arid Central Asia, severely affecting vegetation growth. However, systematic quantitative assessments of vegetation responses and their drivers under such compo...

SlSPL10 mediates nitric oxide-induced suppression of the sugar-acid ratio in postharvest tomato fruit

The sugar-acid ratio is a key determinant of tomato flavor quality during postharvest ripening. Although nitric oxide (NO) has been shown to influence sugar and organic acid metabolism in various fruits, the molecular mechanisms by which NO regulates sugar-acid balance in tomato...

Genome-Wide Characterization and Transcriptomic Analysis Reveal Light-Quality-Responsive RING Zinc Finger Genes in Potatoes

RING-zf E3 ligases play key roles in plant development and light signaling, but their genome-wide characterization and light-responsive functions in potatoes remain largely unexplored. In this study, we identified 291 StRING-zf genes containing complete RING domains in the potato...

Warming and Nitrogen Addition Induce Asynchronous Taxonomic and Functional Responses and Reorganize Microbial C, N, P Cycling Potential in an Alpine Wetland on the Qinghai–Tibet Plateau

Climate warming and atmospheric nitrogen deposition are altering carbon (C), nitrogen (N), and phosphorus (P) cycling in alpine wetlands. However, how these drivers jointly reorganize microbial communities and their biogeochemical cycling potential remains poorly understood, part...

Large-scale solar parks reshape ground arthropod assembly in the Tengger desert

The photovoltaic desertification control model effectively suppresses aeolian activity while promoting vegetation recovery and soil improvement, yet its impact on the diversity and function of ground arthropods remains unclear. This study was conducted at the Jiuduntan Photovolta...

Topographic and economic drivers of agricultural–ecological coupling in Gansu Province: spatial differentiation and threshold effects

Improved understanding of agricultural–ecological coupling is critical for sustainable development in semi-arid regions. This study integrated the Remote Sensing Ecological Index (RSEI), Agricultural Green Development Index (AGDI), Coupling Coordination Degree (CCD) model, and XG...

Distribution and Catalytic Mechanism of a Novel Carboxylesterase Degrading Multiple Aryloxyphenoxypropionate Herbicides in Bacteria and Archaea

Abstract Aryloxyphenoxypropionate (AOPP), a widely used class of herbicides, pose significant risks to ecosystems and human health. In this study, Bacillus amyloliquefaciens L1 was isolated as a novel degrader, completely degrading 97.42 mg/L cyhalofop-butyl within 12 h via ester...

Identification and functional analysis of transcription factor MhWRKY71-like from Malus halliana in response to low temperature

Late spring coldness and late frost during bud burst are major low-temperature disasters in apple production, which seriously hinder the sustainable development of the apple industry. WRKY transcription factors play central regulatory roles in plant responses to abiotic stresses....

Genetic Variation and Haplotype Structure of CFAP299 and PRDM8 Associated with Fiber Yield and Hair Length Traits in Tianzhu White Yak
