A previous exposure to drought priming (DP) or salt (SP) could significantly improve future tolerance both the same and different abiotic stresses, which is an effective mitigation strategy for plants adapt changing environmental conditions. If type of stress from subsequent stress, this indicates that are trained acquire cross tolerance. The objective study was explore DP-regulated SP-induced associated with changes in growth, antioxidant defense, proline metabolism, expression dehydration-responsive gene Dehydrin b involved stabilization membrane systems, cryoprotection intracellular proteins, enhancement water retention capacity white clover (Trifolium repens). Plants were pretreated by initial DP SP then subjected 10 days, respectively. results demonstrated increased number roots during whereas improved stem length, root under indicated exhibited more pronounced positive effects on mitigating drought-induced growth retardant. Both resulted significant increases electrolyte leakage contents superoxide anion, hydrogen peroxide, malonaldehyde due reduced dismutase, catalase, as well key enzyme activities ascorbate–glutathione cycle. enhance these alleviate drought- salt-induced oxidative damage. also accumulation contributing better homeostasis promoting biosynthetic (Δ1-pyrroline-5-carboxylate synthetase aminotransferase) restricting dehydrogenase activity degradation In addition, up-regulated dehydrin but failed induce response stress. current findings proved pre-exposure effectively mitigate negative related some common pathways. adaption regulating physiological, metabolic, transcriptional changes.

Epigenetic Modifications, Immune Control Processes, and Plant Responses to Nematodes

Agriculture, Год журнала: 2025, Номер 15(7), С. 742 - 742

Plants adapt to biotic and abiotic stresses through physiological, morphological, genetic changes. In recent years, the fundamental roles of epigenetic mechanisms as regulators various immune–biological processes in nematode–plant interactions have been increasingly recognized. Epigenetic control include non-coding RNAs (ncRNAs), DNA methylation, histone modifications. Gene expression gene silencing play crucial activated induced resistance during pathogen attacks. methylation modifications are linked defense priming or immune memory, such systemic acquired (SAR). addition, important long-term priming, contributing development immunological memory under future stress conditions. Therefore, advances understanding hold considerable potential for research on plant–nematode interactions. However, further basic among stresses, expansion markers changes, permanence necessary optimize its utilization crop protection programs. this paper, we focus function plant responses nematode infection, specifically root-knot nematodes (RKNs). Understanding adaptive ability RKNs is developing suitable methods. Additionally, explore role with biological agents.

Effect of Drought and Seed Tuber Size on Agronomical Traits of Potato (Solanum tuberosum L.) under In Vivo Conditions

Drought may considerably decrease the growth and yield of potatoes. Small tubers have lower performance be more sensitive to abiotic stresses than larger tubers. Since an increase in drought areas expected, development potato varieties with tolerance has become necessary. Two-year greenhouse experiments were conducted test breeding lines (C103, C107, C20) great osmotic stress tolerance. Minitubers diameters 25–35, 20–24, 15–19 10–14 mm planted. Treatments optimal irrigated control (100%) moderate severe (60% 20% optimum water supply). To study after-effects drought, from different treatments planted separately following year because seed tuber priming Seed (25–35 mm), two irrigation (control drought), cultivars used second year. We observed rate emergence day-after-planting (DAP) 20 30 flowering 48 54. NDVI measurements performed on DAP35-45-75. Plant height fresh weight aboveground biomass (AGB) recorded DAP76. Harvested counted, weighed, size-categorized, then number per plant (TN TY) calculated. Stress indices (SI) calculated as percentages results plots compare responses genotypes stress. found that each line showed adequate tolerance, although only C103 C107 stable vivo conditions.

The size significantly affected character, usually minitubers better smaller ones. No significant after-effect next generation was found. Although we a positive correlation (r = 0.83) between parameters, correlations our not consistent all treatments.

Ultraviolet C (UV-C) flash treatment represents a promising method for priming plants. This study compared the effects of 1 s (flash) and 60 (60 s) UV-C exposures on transcriptome Arabidopsis thaliana L. A dose 200 J m−2 delivered in one second was observed to effectively stimulate plant defenses without causing any adverse health. total 3054 1865 differentially expressed genes (DEGs) were identified treatments, respectively, comparison control Of these, 1131 common both treatments. The affected greater number transcription factors (415 genes) than (254 genes), indicating more pronounced alterations gene expression. resulted significant overexpression heat shock proteins (HSPs), (HSFs), their associated genes, which impacted oxidative stress, proteostasis, genome stability, cell survival, thermotolerance. majority mitochondrial found be upregulated, while photosynthetic exhibited downregulation. These expression patterns coordinate electron transport crosstalk between nucleus, chloroplasts, mitochondria, eliciting an adaptive protective response flash. Additionally, several involved cycle regulation, division, DNA replication. included ATP BMMs, BRCA2 s, IQDs, kinesin complex, MCM CYCs, CDKs, ultimately led arrest as temporary preparation subsequent conditions. present demonstrates that exposure induces distinctive responses through coordinated findings suggest is innovative triggers unique cellular response, prioritizing repair mechanisms potentially enhancing immunity, resilience, priming. It can used resistance inducer stimulator.
