Various abiotic stresses may affect the germination, growth, and yield of direct-seeded vegetable crops. Seed priming with effective antioxidant mediators alleviate these environmental by maintaining uniformity in seed germination improving subsequent health developing seedlings. Salt-induced stress has become a limiting factor for successful cultivation Brassica rapa L., especially Southeast Asian countries. The present study was performed to elucidate efficacy using selenium (Se) mitigating salt-induced oxidative turnip crops reducing uptake Na+. In this study, we administered three different levels Se (Se-1, 75 μmol L-1; Se-2, 100 Se-3, 125 L-1) alone or combination NaCl (200 mM). Conspicuously, salinity Se-2 modulated expression genes, including catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), ascorbate (APX). upregulated stress-responsive genes alleviated salt scavenging higher reactive oxygen species (ROS) level. ameliorative potential (Se-2 = enhanced final percentage, photosynthetic content, seedling biomass production up 48%, 56%, 51%, respectively, under stress. advantageous effects were attributed alleviation through reduction malondialdehyde (MDA), proline, H2O2.

Abiotic stresses are considered as a significant factor restricting horticultural crop productivity and quality. Drought stress is major environmental constraint among the emerging concerns. Plants have susceptibility to drought stress, resulting in marked decline production during last several decades. The development of effective strategies mitigate essential for sustainable agriculture food security, especially considering continuous growth world population. Several studies suggested that exogenous application phytohormone plants can improve tolerance by activating molecular physiological defense systems. Phytohormone pretreatment potential approach alleviating plants. In addition, melatonin, salicylic acid, jasmonates, strigolactones, brassinosteroids, gamma-aminobutyric acid phytohormones function regulators effects stress.

Chemical priming has emerged as a promising area in agricultural research. Our previous studies have demonstrated that pretreatment with low concentration of ethanol enhances abiotic stress tolerance Arabidopsis and cassava. Here, we show treatment induces heat tomato ( Solanum lycopersicon L.) plants. Seedlings the cultivar ‘Micro-Tom’ were pretreated solution then subjected to stress. The survival rates ethanol-pretreated plants significantly higher than those water-treated control Similarly, fruit numbers greater ones. Transcriptome analysis identified sets genes differentially expressed shoots roots seedlings mature green fruits compared Gene ontology using these showed stress-related gene terms found set ethanol-induced genes. Metabolome revealed contents wide range metabolites differed between water- ethanol-treated samples. They included sugars such trehalose, sucrose, glucose, fructose. From our results, speculate is mainly result increased expression encoding late embryogenesis abundant (LEA) proteins, reactive oxygen species (ROS) elimination enzymes, activated gluconeogenesis. results will be useful for establishing ethanol-based chemical technology reduce damage crops, especially Solanaceae.
