    In nature, plants constantly face various biotic and abiotic stresses that impact their growth, development, and productivity. Among these, abiotic stresses often have a more severe impact than biotic stresses. For instance, drought has been reported to cause greater yield losses than the combined impact of all plant pathogens (Gupta et al., 2020). Abiotic stresses are the immediate outcome of climate change, and the magnitude of these stresses has gradually increased every year with the rise in global temperatures. Thus, it has become imperative to study the impact of these stresses on plants and how plants respond to them at different levels to show resilient traits. This includes analysing the plants at morphophysiological, biochemical, and molecular levels. thaliana. Under stress conditions, both H3K4me3 and H3K27me3 exhibited rapid and genespecific redistribution. Interestingly, changes in H3K4me3 and H3K27me3 levels occurred independently on different gene sets, confuting the notion that gene activation under cold stress involves a simple switch from H3K27me3-mediated repression to H3K4me3-mediated activation. Also, the study highlighted a weak correlation between these modifications and the changes in the expression of corresponding genes. Altogether, the study provided a genome-wide perspective on cold-triggered histone methylation dynamics, with a lead for further studies on the roles of these marks on corresponding genes.
