Boron (B) is an essential micronutrient in higher plants, contributing to various physiological processes. However, its protective mechanism mitigating salt stress remained less understood. This study investigates that exogenous boron (0, 1, 2 kg ha- 1) can help alleviate 60, 120 mM NaCl) two soybean cultivars AARI-2021 (V1) and Ajmeri (V2). It examines B role reactive oxygen species (ROS), secondary metabolites, antioxidant defense systems stress. Salt negatively impacted morph-physiological biochemical attributes. supplementation (2 reduced oxidative indicators, such as malondialdehyde (by 18% V1 by 21% V2) hydrogen peroxide 30% 38% V2).

Identification of SNAT Gene Family and Their Response to Abiotic Stress in Citrus

Horticulturae, Journal Year: 2025, Volume and Issue: 11(4), P. 399 - 399

Published: April 9, 2025

Serotonin N-acetyltransferase (SNAT) is a crucial enzyme in the melatonin synthesis pathway, playing an essential role both biosynthesis and plant resistance to abiotic stress. A bioinformatics approach was employed identify members of citrus SNAT gene family analyze their physicochemical properties, structure, conserved domains, phylogenetic relationships, promoter cis-acting elements. Additionally, tissue-specific expression trifoliate orange patterns under stress conditions were examined. This study identified 21 across five genomes, distributed over chromosomes, with majority predicted localize within chloroplasts. These genes characterized by having between 1 8 exons, 0 7 introns, 2 5 motifs. Phylogenetic analysis classified into four subgroups, demonstrating significant collinearity rice. Analysis regions revealed 32 elements, those responsive light, abscisic acid, drought being most common. Expression indicated tissue specificity, highest levels detected leaves. Quantitative real-time PCR showed that PtrSNAT1 notably upregulated various conditions, suggesting its response. Overall, these findings provide critical insights for further functional studies relation responses. Moreover, represents potential target developing rootstocks enhanced

Comparative Transcriptomic Analysis Reveals the Involvement of Auxin Signaling in the Heat Tolerance of Pakchoi under High-Temperature Stress

Agronomy, Journal Year: 2024, Volume and Issue: 14(8), P. 1604 - 1604

Published: July 23, 2024

Pakchoi is a kind of nonheading Chinese cabbage being widely cultivated not only in China but also all over Asia. High temperature major limiting factor influencing the yield and quality pakchoi, while mechanism pakchoi dealing with high-temperature challenges remains largely elusive. In present study, we conducted comparative transcriptomic analysis, which was validated by qPCR, heat-tolerant Xinxiaqing (XXQ) variant Suzhouqing (SZQ) variant, are heat-sensitive under treatment. Gene Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) analyses suggest that high-temperature-induced phytohormones signal transduction, especially auxin regulates heat responses pakchoi. Our further investigations imply high-temperature-activated plays positive role helping deal challenge; IAA-pretreated plants exhibited greater resistance to treatment, probably due induction antioxidant activity. addition, our study identified six shock proteins/factors (HSPs/HSFs) whose up-regulation correlates elevated tolerance Notably, among these heat-responsive factors, HSP20 HSP26.5 regulation signal, this cascade contributes enhancing thermostability crucial high-temperature-responsive factors signaling pathways help understanding coping challenge.
