Population-level annotation of lncRNAs in Arabidopsis reveals extensive expression variation associated with transposable element–like silencing

The Plant Cell, Год журнала: 2023, Номер 36(1), С. 85 - 111

Опубликована: Сен. 8, 2023

Abstract Long noncoding RNAs (lncRNAs) are understudied and underannotated in plants. In mammals, lncRNA loci nearly as ubiquitous protein-coding genes, their expression is highly variable between individuals of the same species. Using Arabidopsis thaliana a model, we aimed to elucidate true scope transcription across plants from different regions study its natural variation. We used transcriptome deep sequencing data sets spanning hundreds accessions several developmental stages create population-wide annotation lncRNAs, revealing thousands previously unannotated loci. While genome, most appear be actively silenced extremely accessions. This high variability largely caused by repressive chromatin levels at High was particularly common for intergenic lncRNAs (lincRNAs), where pieces transposable elements (TEs) present 50% these lincRNA associated with increased silencing variation, such tend targeted TE machinery. created improve our understanding plant genome biology, raising fundamental questions about what causes genome.

Abstract Key message Zebularine-treated wheat uncovered a phenotype with characteristics of an epigenetically regulated trait, but major chromosomal aberrations, not DNA methylation changes, are the cause, making zebularine unsuitable for epigenetic breeding. Breeding to identify disease-resistant and climate-tolerant high-yielding wheats has led yield increases over many years, new hardy, higher yielding varieties still needed improve food security in face climate change. Traditional breeding develop cultivars is lengthy process taking more than seven years from initial cross cultivar release. The speed can be enhanced by using modern technologies including high-throughput phenomics, genomic selection, directed mutation via CRISPR. Here we test concept modifying gene regulation transiently disrupting methyltransferase inhibitor, (Zeb), as means uncover novel phenotypes elite facilitate controlled traits. development architecture inflorescence, spikelet density, important component yield, both grain size number have been extensively modified during domestication cultivars.

Epigenetics in evolution and adaptation to environmental challenges: pathways for disease prevention and treatment

Epigenomics, Год журнала: 2025, Номер unknown, С. 1 - 17

Опубликована: Фев. 13, 2025

Adaptation to challenging environmental conditions is crucial for the survival/fitness of all organisms. Alongside genetic mutations that provide adaptive potential during challenges, epigenetic modifications offer dynamic, reversible, and rapid mechanisms regulating gene expression in response changes both evolution daily life, without altering DNA sequences or relying on accidental favorable mutations. The widespread conservation diverse – like methylation, histone modifications, RNA interference across species, including plants underscores their significance evolutionary biology. Remarkably, environmentally induced alterations are passed daughter cells inherited transgenerationally through germline cells, shaping offspring phenotypes while preserving memory. Throughout anthropoid evolution, have played roles in: i) suppressing transposable elements viral genomes intruding into host genome; ii) inactivating one X chromosomes female balance dosage; iii) imprinting ensure from parental allele; iv) functional alleles compensate dysfunctional ones; v) modulating epigenome transcriptome influence gut microbiome among other functions. Understanding interplay between factors processes may valuable insights developmental plasticity, dynamics, disease susceptibility.

Genome-wide association study (GWAS) provides insights into the genomic basis of reproduction-related traits in Chouardia litardierei (Asparagaceae)

BMC Plant Biology, Год журнала: 2025, Номер 25(1)

Опубликована: Май 2, 2025

Chouardia litardierei, commonly known as amethyst meadow squill, is a plant species characterized by profound ecological plasti vcity. As wild, non-model species, it represents suitable system for gaining insights into the genomic background of local adaptation process. By implementing genome-environment and genome-wide association studies, we sought to investigate regions related development several reproduction-related traits in C. litardierei: sexual reproduction, Average Height Inflorescences (AHI) Total Flower Count (TFC) per genotype, asexual Bulb (BC) genotype. A (GEA) study selected litardierei populations revealed precipitation coldest quarter bioclimatic variable with most substantial influence on detected variability, numerous candidate genes functionally characterized. To evaluate genetic basis combined phenotypic data 214 individuals raised part common garden experiment ddRADseq genotyping results. After various single- multi-locus GWAS models all traits, multiple loci affecting their were recognized. In addition, high, narrow-sense heritability estimates indicated that factors accounted over 55% variance each trait. Notably, highest estimate was observed (71.95%), suggesting its crucial role reproductive success. Functional annotation associated identified key protein families involved biological pathways, including nitrogen metabolism, phytohormone regulation, floral organs development. GEA GWAS, list significantly specific environmental variables morphological reproduction litardierei. These findings provide foundation deeper understanding molecular mechanisms driving processes occurring among from different habitat types. At same time, high further underscore significance

Organisms adapt to different environments by selection of the most suitable phenotypes from standing genetic variation or phenotypic plasticity, ability single genotypes produce in environments. Because near identity, asexually reproducing populations are particularly for investigation potential and molecular underpinning latter alternative depth. Recent analyses on whole-genome scale differently adapted clonal animals plants demonstrated that epigenetic mechanisms such as DNA methylation, histone modifications non-coding RNAs among pathways supporting plasticity is used stably Case studies revealed habitat-specific fingerprints were maintained over subsequent years pointing at existence ecotypes. Environmentally induced epimutations corresponding gene expression changes provide an ideal means fast directional adaptation changing new conditions, because they can synchronously alter many population members. microorganisms inclusive human pathogens also exploit epigenetically mediated environmental adaptation, this phenomenon considered a universal biological principle. The production same sequence response cues provides mechanistic explanation “general-purpose genotype hypothesis” “genetic paradox invasions”.
