  "abstract": "Soil salinization threatens sustainable agriculture by reducing crop growth and yield. Stress priming, in which seedlings experience mild salt treatment followed by recovery before re-exposure, can enhance tolerance, but its molecular basis in legumes is unclear. Here, we used mung bean (Vigna radiata) to compare primed and non-primed plants under subsequent salt stress. Primed plants rapidly accumulated proline, activated antioxidant enzymes, and maintained lower Na⁺/K⁺ ratios at early stages. During intermediate stress, defense- and hormone-related transcripts remained elevated, sustaining physiological advantages. At later stages, primed plants preserved chlorophyll, reduced malondialdehyde accumulation, and limited electrolyte leakage, coinciding with persistently accessible stress-responsive promoters enriched for bZIP class A-like motifs. Genome-wide DNA methylation diverged, with primed plants retaining higher CpG, CHG, and CHH methylation and upregulating heterochromatin maintenance factors. These results reveal a temporal, multi-layer regulatory framework linking transcription, chromatin accessibility, and DNA methylation that underpins salt priming in mung bean.",
