Uncovering key salt-tolerant regulators through a combined eQTL and GWAS analysis using the super pan-genome in rice

National Science Review, Journal Year: 2024, Volume and Issue: 11(4)

Published: Feb. 5, 2024

ABSTRACT For sessile plants, gene expression plays a pivotal role in responding to salinity stress by activating or suppressing specific genes. However, our knowledge of genetic variations governing response salt remains limited natural germplasm. Through transcriptome analysis the Global Mini-Core Rice Collection consisting panel 202 accessions, we identified 22 345 and 27 610 quantitative trait loci associated with 7787 9361 eGenes under normal salt-stress conditions, respectively, leveraging super pan-genome map. Notably, combined genome-wide association studies, swiftly pinpointed potential candidate STG5—a major salt-tolerant locus known as qSTS5. Intriguingly, STG5 is required for maintaining Na+/K+ homeostasis directly regulating transcription multiple members OsHKT family. Our study sheds light on how variants influence dynamic changes provides valuable resource mining genes future.

Dynamic molecular regulation of salt stress responses in maize (Zea mays L.) seedlings

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: Feb. 25, 2025

Maize ranks among the most essential crops globally, yet its growth and yield are significantly hindered by salt stress, posing challenges to agricultural productivity. To utilize saline-alkali soils more effectively enrich maize germplasm resources, identifying salt-tolerant genes in is essential. In this study, we used a inbred line, SPL02, salt-sensitive Mo17. We treated both lines with 180 mmol/L sodium chloride (NaCl) for 0 days, 3 6 9 days at three-leaf stage (V3). Through comprehensive morphological, physiological, transcriptomic analyses, assessed stress effects identified hub pathways associated tolerance. Our analysis 25,383 expressed genes, substantial differences gene expression patterns across treatment stages. found 8,971 differentially (DEGs)-7,111 unique SPL02 4,791 Mo17-indicating dynamic changes under stress. DEGs primarily MAPK signaling pathway, phenylpropanoid biosynthesis, hormone conditions. Mo17, responses mediated through abscisic acid-activated pathway response. Additionally, our weighted co-expression network (WGCNA) pinpointed five that likely play central roles mediating These functions including phosphate import ATP-binding protein, glycosyltransferase, WRKY transcription factors. This study offers valuable insights into complex regulatory networks governing response identifies further investigation. findings contribute knowledge enhancing resilience sustainability saline-affected environments.

Ion Changes and Signaling under Salt Stress in Wheat and Other Important Crops

Plants, Journal Year: 2023, Volume and Issue: 13(1), P. 46 - 46

Published: Dec. 22, 2023

High concentrations of sodium (Na+), chloride (Cl−), calcium (Ca2+), and sulphate (SO42−) are frequently found in saline soils. Crop plants cannot successfully develop produce because salt stress impairs the uptake Ca2+, potassium (K+), water into plant cells. Different intracellular extracellular ionic change with salinity, including those K+, protons. These cations serve as signaling molecules addition to being essential for homeostasis nutrition. Maintaining an appropriate K+:Na+ ratio is one crucial mechanism tolerance, which a complicated trait. Another important ability fast extrusion Na+ from cytosol. Ca2+ established ubiquitous secondary messenger, transmits various signals metabolic alterations that cause adaptive responses. When under stress, cytosolic-free concentration can rise 10 times or more its resting level 50–100 nanomolar. Reactive oxygen species (ROS) linked produced by stress. Depending on type, frequency, intensity cytosolic oscillate, transient, persist longer period exhibit specific “signatures”. Both influx efflux affect length amplitude signal. According several reports, occur not only cytoplasm cell but also walls, nucleus, other organelles waves propagate through whole plant. Here, we will focus how wheat crops absorb Na+, Cl− when well pH homeostasis. Similar mechanisms model Arabidopsis be considered.
