The methylation- demethylation dynamics of RNA plays major roles in different biological functions, including stress responses, plants. m6A methylation is orchestrated by a coordinated function methyl transferases (writers) and demethylases (Erasers). Genome-wide analysis genes involved was performed pigeon pea. Blast search, using Arabidopsis gene sequences, resulted the identification two (CcMTA70, CcMTB70), encoding adaptor proteins for (CcFIPA CcFIPB) 10 demethylase (ALKBH) (CcALKBH1A, CcALKBH1B, CcALKBH1C, CcALKBH2, CcALKBH8, CcALKBH8A, CcALKBH8B, CcALKBH9, CcALKBH10A CcALKBH10B) pea genome. identified were analyzed through phylogenetic relationship, chromosomal position, structure, conserved motif, domain subcellular location prediction etc. These structural analyses categorization MTs FIPs into one group, i.e., CcMTA/B CcFIPA/B, respectively; ALKBHs four groups, viz. CcALKBH1/2, CcALKBH9 CcALKBH10. Relative expression various tissues at developmental stages revealed highest level leaf least root. CcMTs CcFIPs had similar patterns expression, CcALKBH10B demonstrated CcALKBH2 lowest all analyzed. CcALKBH8 showed induction upon exposure to heat stress, during drought, salt biotic (Helicoverpa armigera infestation) stresses. present study would pave way detailed molecular characterization its involvement regulation.

The increased frequency of extreme weather events related to climate change, including the occurrence temperatures, severely affects crop yields, impairing global food security. Heat stress resulting from temperatures above 30 °C is associated with poor germination performance and stand establishment. combination climate-resilient genotypes tailored seed priming treatments might represent a reliable strategy overcome such drawbacks. This work explores potential hydropriming as tool mitigate heat-stress-mediated impact on in orphan legumes. For each tested species (Lathyrus sativus L., Pisum sativum var. arvense Trigonella foenum-graecum L.), two accessions were investigated. Germination tests performed at 25 °C, 35 40 assess heat tolerance threshold. Hydropriming was then applied test treatment seeds' ability cope stress. An alkaline comet assay Quantitative Real Time-Polymerase Chain Reaction embryos excised primed control seeds. Phenotyping seedling development stage highlighted accession-specific beneficial under conditions. In L. seeds, revealed dynamics stress-induced DNA damage accumulation, well repair patterns promoted by hydropriming. expression genes involved antioxidant response consistently responsive wave conditions accessions.
