NtPhyA gene knockout enhances cold stress resistance in Nicotiana tabacum L.

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.

L. Extract Inhibits Colorectal Cancer Tumor Growth by Modulating Cell Apoptosis and Autophagy.

Colorectal cancer (CRC) is a common cancer globally, and chemotherapy often causes severe complications, necessitating effective drugs with minimal side effects. As L. extract (ACE) is a Traditional Chinese Medicine that contains numerous active compounds with anticancer effects, in this study, the Cell Counting Kit-8 (CCK-8) assay was used to determine ACE's effect on CRC cell lines, revealing that it significantly inhibits CoLo320DM and HCT116 cells.

Enhanced coagulation of Microcystis aeruginosa using titanium xerogel coagulant.

Cyanobacterial blooms are prevalent globally and present a significant threat to water security. 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.

Revealing the key role of the folate synthesis regulatory gene DHNA in tobacco leaf yellowing based on BSA-seq, RNA-seq, and proteomic sequencing.

Background: The degree of yellowing in tobacco leaves is an important indicator for determining the maturity and harvesting time of tobacco leaves. 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.

Construction and evaluation of a model for efficient identification of photothermal sensitivity of tobacco cultivars based on agronomic traits.

The photothermal sensitivity of tobacco refers to the degree to which tobacco responds to changes in light and temperature conditions in its growth environment, which is crucial for determining the planting area of cultivars and improving tobacco yield and quality. 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.
