Background: Assessing the relationships between spatial and temporal structures and functions of plant communities is an effective way to understand the changing dynamics of plant communities in specific environments. In this study, we investigated the response of structural and functional stabilities of plant communities to stocking rate in the desert steppe over a 16-year grazing period as the research background.
Methods: We used classical statistical methods to investigate the quantitative characteristics of plant communities over time (2014-2019) and space (2017-2019) at four stocking rates (control, CK, 0 sheep·ha·month; light grazing, LG, 0.15 sheep·ha·month; moderate grazing, MG, 0.30 sheep·ha·month; heavy grazing, HG, 0.45 sheep·ha·month) in the Stipa breviflora desert steppe of Inner Mongolia. We then examined the relationship between structural and functional stability of plant communities.
Results: On the spatial scale, the structural stability of plant community was the highest in the LG treatment and the lowest in the MG treatment. The functional stability of plant community was the highest in the MG treatment and the lowest in the HG treatment. On the temporal scale, the structural stability of plant community was the highest in the MG treatment and the lowest in the LG treatment. The functional stability of plant community was the highest in the LG treatment and the lowest in the HG treatment. Affected by the stocking rate, the structural stability of plant community fluctuated more widely on the spatial scale and its functional stability varied more widely on the temporal scale. Nonetheless, the functional stability of the plant community is more responsive to the stocking rate.
Conclusions: Our findings suggest that influenced by the disturbance of stocking rate, the structural stability of plant community is more significant than the functional stability in the desert grassland ecosystem, which lays a solid foundation for the study of ecosystem stability.

This comprehensive review explores the emergence of titanium dioxide nanoparticles (TiO-NPs) as versatile nanomaterials, particularly exploring their biogenic synthesis methods through different biological entities such as plants, bacteria, fungi, viruses, and algae. These biological entities provide eco-friendly, cost-effective, biocompatible, and rapid methods for TiO-NP synthesis to overcome the disadvantages of traditional approaches. TiO-NPs have distinctive properties, including high surface area, stability, UV protection, and photocatalytic activity, which enable diverse applications.

Background: The aim of this study is to investigate the effect of soil water stability on maize (Zea mays L.) yield, water use, and its photosynthetic physiological mechanisms, and to innovate the relationship between maize and soil water, which currently only considers soil water content and neglects soil water stability.
Methods: An organized water experiment was conducted on maize.

In animal cells, Gα subunit of the heterotrimeric G proteins can bind to both the N-terminal and C-terminal domains of G-protein-activated inwardly rectifying K channels (GIRKs) to inhibit their activities. In Arabidopsis guard cells, the Gα subunit GPA1 mediates multiple stimuli-regulated stomatal movements via inhibiting guard cell inward-rectifying K (K) current, but it remains unclear whether GPA1 directly interacts with and inhibits the activities of K channels. Here, we found that GPA1 interacted with the transmembrane domain rather than the intracellular domain of the Shaker family K channel KAT1.

Hydrogels in agriculture offer controlled release, however, face issues with rapid disintegration, swift release, and inability to protect active ingredients. To overcome this, the study presents a hydrogel delivery system that uses dopamine-functionalized nanoporous diatom (DE-PDA) microparticles entrapped in alginate and chitosan matrices to deliver plant growth hormone, gibberellic acid (GA) that suffers from instability, limiting its field application. Developed GA@hydrogel beads exhibited an encapsulation efficiency of 85.
