Abstract Chromatin plays a crucial role in genome compaction and is fundamental for regulating multiple nuclear processes. Nucleosomes, the basic building blocks of chromatin, are central these processes, determining chromatin accessibility by limiting access to DNA various proteins acting as important signaling hubs. The association histones with nucleosomes folding into higher-order structures strongly influenced variety epigenetic marks, including methylation, histone variants, post-translational modifications. Additionally, wide array chaperones ATP-dependent remodelers regulate aspects nucleosome biology, assembly, deposition, positioning. This review provides an overview recent advances our mechanistic understanding how organization regulated marks plants. Furthermore, we present current technologies profiling organization.

Abstract Wheat is the most widely cultivated crop in world with over 215 million hectares grown annually. However, to meet demands of a growing global population, breeders face challenge increasing wheat production by approximately 60% within next 40 years. The 10+ Genomes Project recently sequenced and assembled chromosome level genomes nine cultivars develop our understanding genetic diversity selection pan-genome wheat. Here, we provide pan-transcriptome de novo annotation differential expression analysis for these cultivars, across multiple different tissues whole seedlings sampled at dusk/dawn. Analysis annotations facilitated discovery genes absent from Chinese Spring reference, identified specific particular defined core dispensable genomes. Expression revealed conservation between large set homeologous genes, but also widespread changes subgenome homeolog bias cultivars. Co-expression network impact divergence sub-genome cultivar-specific profiles. In case study utilising both newly constructed demonstrate prevalent variation prolamin superfamily immune-reactive proteins pan-cultivars.In summary, this work provides valuable resource wider community reveals gene content patterns

Genetic information in eukaryotic organisms is stored, replicated, transcribed, and inherited through the nucleus of a cell. Epigenetic modifications genetic material, including DNA methylation, histone modification, changes non-coding RNA (ncRNA) biogenesis, chromatin architecture play important roles determining genomic landscape regulating gene expression. Genome (structural features chromatin, affected by epigenetic modifications) major driver functions/activities. Segregation euchromatin (transcriptionally active) from heterochromatin repressed chromosome) positioning genes specific nuclear space cells emphasise non-randomness organization information. Not only does base sequence carry but covalent bases, three-dimensional genome, loops are vital for switching on/off its expression during growth/environmental stress. The dynamics depend on activities writers erasers under changing environmental conditions. discovery RNAs (one players de novo methylation DNA), increased protein (guide demethylase), monitoring (that helps keep balance between demethylation methylation) have been some new developments era epigenomics. To respond to stimuli, plants modulating different mechanisms biochemical, molecular, genetic, alterations. Studies might provide better insights into stress memory molecular bases adaptability enable (epi)genome editing crops climate resilience sustainable agriculture present multifaceted change.
