N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q), an oxidative derivative of tire anti-degradant, has been linked to mortality in coho salmon (Oncorhynchus kisutch) and has exhibited potential human toxicity. Hence, exploring how 6PPD-Q interacts with biomacromolecules like enzymes is indispensable to assess its human toxicity and elucidate its mechanism of action. This investigation aims to explore the impact of 6PPD-Q on lactate dehydrogenase (LDH) through various methods.

Under the influence of climate warming, overgrazing may exacerbate ecosystem degradation. To determine the safe grazing boundaries and potential degradation areas in different regions. The study used the Generalize Linear Model (GLM) to assess the combined effects of drought and grazing on the ecosystem services of the Tibetan Plateau (TP), and identified safe grazing boundaries and overgrazing areas.

Rab GTPases are a class of small GTP-binding proteins, play crucial roles in the membrane transport machinery with in eukaryotic cells. They dynamically regulate the precise targeting and tethering of transport vesicles to specific compartments by transitioning between active and inactive states. In plants, Rab GTPases are classified into eight distinct subfamilies: Rab1/D, Rab2/B, Rab5/F, Rab6/H, Rab7/G, Rab8/E, Rab11/A, and Rab18/C.

Electronic address:
Photosynthesis drives crop growth and production, and strongly affects grain yields; therefore, it is an ideal trait for wheat drought resistance breeding. However, studies of the negative effects of drought stress on wheat photosynthesis rates have lacked accurate evaluation methods, as well as high-throughput techniques. We investigated photosynthetic capacity under drought stress in wheat varieties with varying degrees of drought stress resistance using hyperspectral and chlorophyll fluorescence (ChlF) imaging data.
