The high-affinity potassium transporter (HKT) genes are essential for plant salt stress tolerance. However, there were limited studies on HKTs in maize (), and it is basically unknown whether natural sequence variations in these genes are associated with the phenotypic variability of salt tolerance. Here, the characterization of was reported. Under salt stress, expression increased strongly in salt-tolerant inbred lines, which accompanied a better-balanced Na/K ratio and preferable plant growth. The association between sequence variations in and salt tolerance was evaluated in a diverse population comprising 54 maize varieties from different maize production regions of China. Two SNPs (A134G and A511G) in the coding region of were significantly associated with different salt tolerance levels in maize varieties. In addition, the favorable allele of identified in salt tolerant maize varieties effectively endowed plant salt tolerance. Transgenic tobacco plants of overexpressing the favorable allele displayed enhanced tolerance to salt stress better than overexpressing the wild type . Our research showed that expression could effectively enhance salt tolerance by maintaining an optimal Na/K balance and increasing the antioxidant activity that keeps reactive oxygen species (ROS) at a low accumulation level. Especially, the two SNPs in might be related with new amino acid residues to confer salt tolerance in maize. Two SNPs of related with salt tolerance were identified by association analysis. Overexpressing in tobaccos showed that the SNPs might enhance its ability to regulating Na/K homeostasis.
Phenol is one of the major organic pollutants in high salt industrial wastewater. The biological treatment method is considered to be a cost-effective and eco-friendly method, in which the co-culture of microalgae and bacteria shows a number of advantages. In the previous study, a co-culture system featuring () and () was established and could degrade 400 mg L phenol at 3% NaCl concentration.

Recent studies have demonstrated that the primary transcript of miRNAs (pri-miRNAs) are able to encode small peptides influencing plant growth and development, as well as responses to various environmental cues. However, their role in plant responses to salt stress is not fully comprehended. Here, we characterized a short peptide encoded by miR172b (miPEP172b) in rice (Oryza sativa L.
Salt damage is a major issue that causes a decline in crop yield. WRKY transcription factors (TFs) extensively regulate plant biotic and abiotic stress responses, growth, and development. WRKY45 is crucial in regulating leaf senescence, low phosphorus responses, and cadmium stress response in Arabidopsis.
Interfacial solar steam generation (ISSG) employed for seawater desalination and wastewater purification shows great promise to alleviate global freshwater scarcity. However, simultaneous optimization of water transfer direction in a cost-effective and reliable ISSG to balance thermal localization, salt accumulation, and resistance to oilfouling represents a rare feat. Herein, inspired by seabird beaks for unidirectional water transfer, eco-friendly and cost-effective plant extracts, sodium alginate, and tannic acid, are selected for crafting an innovative Sodium Alginate-Tannic Acid Hemispheric Evaporator (STHE).
