Cold stress-mediated reduced photosynthesis and osmotic stress severely endanger and limit plant development and crop yield. We investigated the expression of the NtPhyA (phytochrome A) gene in wild-type K326 and the defence response of PhyA knockout mutants under cold stress to monitor their physiological changes. PhyA mutants exhibited greater cold tolerance than wild-type (WT) plants, with lower levels of reactive oxygen species and malondialdehyde.

Titanium salt coagulants have garnered considerable attention due to their superior coagulation properties and the absence of metal residue risks. This paper explored the influencing factors in the coagulation process of titanium xerogel coagulant (TXC), the alterations in cell activity during floc storage, and the release of cyanobacterial organic matters, thereby determining the application scope of TXC for cyanobacterial water treatment.

Decreasing chlorophyll levels helps speed up the ripening process of tobacco leaves for easier mechanical harvesting. Identifying and utilizing genes that regulate yellowing in tobacco leaves are crucial for developing tobacco varieties suitable for mechanized harvesting and understanding the molecular processes that control leaf color changes.

In order to accurately and effectively evaluate the photothermal sensitivity of tobacco cultivars, this study selected five cultivars and their hybrid combinations with significant differences planted under different ecological conditions from 2021 to 2022 as materials. The experiment was conducted in two locations with significant differences in temperature and light.
