Introduction: Grazing management is essential to maintain the stability of grassland ecosystems.
Methods: To determine the optimal rest-grazing period of alpine meadow, five rest-grazing periods were set based on soil thawing and plant re-greening in this study. The niche, interspecific relationships, and stability of plant communities at different rest-grazing periods were investigated.
Results: Rest-grazing during soil thawing resulted in a small niche width and niche overlap of plants, overall positive interspecific associations, and a high stability of plant communities. Delayed rest-grazing time to plant re-greening resulted in a large niche width and niche overlap of plants, overall negative interspecific associations, and a low stability of plant communities.
Discussion: Rest-grazing in alpine meadows should begin as soon as possible to promote healthy and sustainable utilization of grasslands.

The Mediterranean Basin, a hotspot for tomato production, is one of the most vulnerable areas to climate change, where rising temperatures and increasing soil and water salinization represent major threats to agricultural sustainability. Thus, to understand the molecular mechanisms behind plant responses to this stress combination, an RNA-Seq analysis was conducted on roots and shoots of tomato plants exposed to salt (100 mM NaCl) and/or heat (42°C, 4 h each day) stress for 21 days. The analysis identified over 8000 differentially expressed genes (DEGs) under combined stress conditions, with 1716 DEGs in roots and 2665 in shoots being exclusively modulated in response to this specific stress condition.

Recent evidence suggests that parasite-mediated reductions in food intake (i.e., anorexia) in herbivores can trigger trophic cascades that increase producer biomass.

Introduction: Breast cancer is the most common malignancy among women and the second leading cause of cancer-related deaths worldwide. Resveratrol, a polyphenolic stilbene derivative found in grapes, red wine, and other plants, possesses anti-cancer properties. Various studies have reported the potential of different nanomaterials to act as radiosensitizers against tumor cells.

Ginseng exosomes are a kind of promising extracellular vesicle containing unique bioactive components. However, the investigation on ginseng-derived exosomes is still in the initial stage. This study developed a photonic crystal-based Bragg scattering coupling electrochemiluminescence (BSC-ECL) biosensor for detection of miRNA396a-3p in exosome-like nanoparticles (GENs) and ginseng exosomes (Gexos).

Plant diseases caused by bacteria affect the yield of crop, greatly reduce the quality of food, and thus posing a great threat to food safety. To fill the gap that no report about ClpP inhibitor is applied in agri-food production field, engineering natural-product repurposing strategy, 55 of natural products were screened using the combination of ClpP inhibitors of Xanthomonas oryzae pv. oryzae (Xoo) screening assay and anti-Xoo activity experiment.
