Background: Plants face a wide range of environmental stresses that disrupt growth and productivity. To survive adapt, they undergo complex metabolic reprogramming by redirecting carbon nitrogen fluxes toward the biosynthesis protective secondary metabolites such as phenylpropanoids, flavonoids, lignin. Recent research has revealed these stress-induced processes are tightly regulated epigenetic mechanisms, including DNA methylation, histone modifications, chromatin remodeling, non-coding RNAs. Methods: This review synthesizes current findings from studies on both model crop plants, examining roles key regulators in controlling metabolism under stress. Special focus is placed dynamic changes acetylation, action small RNAs siRNAs miRNAs transcriptional post-transcriptional regulation. Results: Evidence indicates stress triggers rapid reversible modifications modulate gene expression linked to pathways. These not only facilitate immediate responses but can also contribute memory. In some cases, this memory retained transmitted next generation, influencing progeny responses. However, critical knowledge gaps remain, particularly concerning temporal dynamics, tissue specificity, long-term stability marks crops. Conclusions: Understanding how regulation governs metabolite production offers promising avenues enhance resilience productivity context climate change. Future should prioritize dissecting heritability support development epigenetically informed breeding strategies.

Mutagenesis breeding via ethyl methanesulfonate (EMS) has been successfully used in faba bean to improve some economically important traits. However, there is a knowledge gap of the factors/mechanisms related its sensitivity/tolerance EMS treatment toxicity. It was hypothesized that seed size could influence response diverse botanical varieties bean. Consequently, we conducted comprehensive assessment sensitivity six varieties: three major (Aguadulce superlonga, Reina mora, and Yasmine) minor (Zina, Alfia 05, 17), increasing concentrations (0.05%, 0.5%, 1%, along with control 0%) EMS. Analyses included various germination parameters (germination percentage [GP], energy at seven 14 days [GE7 GE14], rate index [GRI], vigor [VI]) across different concentrations. To further explore mechanisms involved EMS, measured coat thickness assessed antioxidant activity. Our findings revealed variation did not significantly affect sensitivity. Different showed significant responses ( p ≤ 0.05) for most parameters, except root length. This challenges assumption influences Coat uniform, suggesting similar absorption. DPPH assay activity differences between nontreated EMS‐treated groups. Antioxidant correlated under treatment. The study indicates factors beyond contribute responses. Examining systems may explain plants’ ability counteract EMS‐induced oxidative stress.

As the global population continues to grow, achieving ecological sustainability and ensuring food production have become urgent challenges. Among various environmental stresses, heavy metals, particularly cadmium (Cd), pose a significant threat plant growth development. Breeding cadmium-resistant crop varieties that minimize Cd accumulation is therefore crucial for promoting sustainable agriculture. In response stress, plants undergo series of regulatory mechanisms, including DNA methylation, chromatin remodeling, histone acetylation, mitigate cellular damage. Understanding epigenetic responses stress key research area holds substantial significance both agriculture biology. This article reviews current on underlying mechanisms their responses, aiming provide theoretical insights analyzing metal in major crops. We can leverage genomics, single-cell sequencing, stereo-seq, other advanced technologies conjunction with epigenomics, genetics molecular biology techniques conduct comprehensive in-depth studies changes occur following exposure. Systematically elucidating by which perceive respond will aid development more effective bioremediation strategies metal-contaminated soils facilitate.
