AI Article Synopsis
- Salt stress negatively affects nitrogen fixation in legumes by decreasing nodule number, weight, and nitrogenase activity.
- A study by He et al. indicates that glycogen synthase kinase 3 (GSK3) plays a role in this process by phosphorylating nodulation signaling pathway 1 (NSP1).
- This phosphorylation reduces NSP1's ability to bind to DNA, leading to decreased nodulation in response to salt stress.
Article Abstract
Salt stress reduces N fixation by causing a reduction in nodule number, nodule weight, and nitrogenase activity in legumes. Emerging evidence from He et al. now suggests that glycogen synthase kinase 3 (GSK3) phosphorylates nodulation signaling pathway 1 (NSP1) in response to salt stress, reducing its DNA-binding activity, and thereby causing a reduction in nodulation.

Background: The Sec14 domain is an ancient lipid-binding domain that evolved from yeast Sec14p and performs complex lipid-mediated regulatory functions in subcellular organelles and intracellular traffic. The Sec14 family is characterized by a highly conserved Sec14 domain, and is ubiquitously expressed in all eukaryotic cells and has diverse functions. However, the number and characteristics of Sec14 homologous genes in soybean, as well as their potential roles, remain understudied.

Nano-biochar considers a versatile and valuable sorbent to enhance plant productivity by improving soil environment and emerged as a novel solution for environmental remediation and sustainable agriculture in modern era. In this study, roles of foliar applied nanobiochar colloidal solution (NBS) on salt stressed tomato plants were investigated. For this purpose, NBS was applied (0%, 1% 3% and 5%) on two groups of plants (control 0 mM and salt stress 60 mM).

Under salt stress, plasma membrane proteins regulate ion homeostasis and the balance between reactive oxygen species (ROS). In this study, we investigated the functions of two small membrane proteins-MsRCI2B (tailless) and MsRCI2E (tailed)-encoded by the RCI2 (Rare Cold Inducible 2) gene family in Medicago sativa (alfalfa). We identified the distinct subcellular localization and expression patterns of these proteins under salt stress.

Salt stress severely affects the growth and development of tomato. Strigolactones (SLs) and DNA methylation have been shown to be involved in the growth and development and response to salt stress in tomato. However, the regulation of SLs on DNA methylation in tomato under salt stress remains unclear.

Purpose: To introduce and validate quantitative oblique back-illumination microscopy (qOBM) as a label-free, high-contrast imaging technique for visualizing conjunctival goblet cells (GCs) and assessing their functional changes.
Methods: qOBM was developed in conjunction with moxifloxacin-based fluorescence microscopy (MBFM), which was used for validating GC imaging. Initial validation was conducted with polystyrene beads, followed by testing on normal mouse conjunctiva under both ex-vivo and in-vivo conditions.
