Role of Epigenetics in Modulating Phenotypic Plasticity against Abiotic Stresses in Plants by Fayaz Ahmad Dar, Naveed Ul Mushtaq, Seerat Saleem, Reiaz Ul Rehman, Tanvir Ul Hassan Dar, Khalid Rehman Hakeem

“…Epigenomics refers to the large-scale study of epigenetic marks on the genome, which include covalent modifications of histone tails (acetylation, methylation, phosphorylation, ubiquitination, and the small RNA machinery). Studies based on epigenetics have evolved over the years especially in understanding the mechanisms at transcriptional and posttranscriptional levels in plants against various environmental stimuli. …”

Decoding the general role of tRNA queuosine modification in eukaryotes by Jorge Díaz-Rullo, Luis González-Moreno, Araceli Del Arco, José Eduardo González-Pastor

“…Here, through bioinformatics analysis of representative eukaryotic genomes we have predicted: i) the genes enriched in NAU codons, whose translation would be affected by tRNA Q-modification (Q-genes); and ii) the specific biological processes of each organism enriched in Q-genes, which generally in eukaryotes would be related to ubiquitination, phosphatidylinositol metabolism, splicing, DNA repair or cell cycle. …”
