[Influence of Polystyrene Microplastics on the Formation and Structural Change of Biofilm].

Microplastic pollution in the water environment is becoming increasingly serious, impacting the growth and development of aquatic organisms. There are limited studies on the mechanisms of microplastic effects on biofilm formation. Therefore, in this study, the effects of polystyrene microplastics (PS-MPs) were investigated on the biofilm formation and development of .

Genome-Wide Analysis of the RAV Gene Family in Wheat and Functional Identification of TaRAV1 in Salt Stress.

RAV transcription factors (TFs) are unique to higher plants and contain both B3 and APETALA2 (AP2) DNA binding domains. Although sets of RAV genes have been identified from several species, little is known about this family in wheat. In this study, 26 RAV genes were identified in the wheat genome.

MYB77 regulates high-affinity potassium uptake by promoting expression of HAK5.

In Arabidopsis, the high-affinity K transporter HAK5 is the major pathway for root K uptake when below 100 µM; HAK5 responds to Low-K (LK) stress by strongly and rapidly increasing its expression during K -deficiency. Therefore, positive regulators of HAK5 expression have the potential to improve K uptake under LK. Here, we show that mutants of the transcription factor MYB77 share a LK-induced leaf chlorosis phenotype, lower K content, and lower Rb uptake of the hak5 mutant, but not the shorter root growth, and that overexpression of MYB77 enhanced K uptake and improved tolerance to LK stress.
