Despite the known collective contribution of above- (plants) and below-ground (soil fungi) biodiversity on multiple soil functions, how the associations among plant and fungal communities regulate soil multifunctionality (SMF) differentially remains unknown. Here, plant communities were investigated at 81 plots across a typical arid inland river basin, within which associated soil fungal communities and seven soil functions (nutrients storage and biological activity) were measured in surface (0-15 cm) and subsurface soil (15-30 cm). We evaluated the relative importance of species richness and biotic associations (reflected by network complexity) on SMF.

Phytomelatonin is a pleiotropic signaling molecule that regulates plant growth, development, and stress response. In plant cells, phytomelatonin is synthesized from tryptophan several consecutive steps that are catalyzed by tryptophan decarboxylase (TDC), tryptamine 5-hydroxylase (T5H), serotonin -acyltransferase (SNAT), and -acetylserotonin methyltransferase (ASMT) and/or caffeic acid-3--methyltransferase (COMT). Recently, the identification of the phytomelatonin receptor PMTR1 in has been considered a turning point in plant research, with the function and signal of phytomelatonin emerging as a receptor-based regulatory strategy.

Exploring more emissions reduction opportunities for China's energy sector and lowering China's decarbonisation costs are essential to fulfilling China's nationally determined contributions (NDCs) and making China's sustainable development more feasible. This study explored emissions reduction opportunities for China's energy sector in international bilateral emissions trading systems (ETSs) using a CGE (computable general equilibrium) model. This study revealed that linking China's ETS to those of regions with lower decarbonisation responsibilities, which tend to be developing regions, could lower China's carbon prices, thus increasing China's domestic energy supply and lowering energy prices (and vice versa).

To characterize the cold tolerance mechanism of the Pacific white shrimp (), we performed single-cell RNA sequencing (scRNA-seq) of ∼5185 hepatopancreas cells from cold-tolerant (Lv-T) and common (Lv-C) at preferred and low temperatures (28°C and 10°C, respectively). The cells fell into 10 clusters and 4 cell types: embryonic, resorptive, blister-like, and fibrillar. We identified differentially expressed genes between Lv-T and Lv-C, which were mainly associated with the terms "immune system," "cytoskeleton," "antioxidant system," "digestive enzyme," and "detoxification," as well as the pathways "metabolic pathways of oxidative phosphorylation," "metabolism of xenobiotics by cytochrome P450," "chemical carcinogenesis," "drug metabolism-cytochrome P450," and "fatty acid metabolism.
