ABSTRACT Aquatic animal germplasm research plays a vital role in biodiversity conservation and sustainable aquaculture. The traditional view is that diversity of resources commonly attributed to genetic variation. However, recent studies transgenerational epigenetics have shown epigenetic information can also be passed down offspring, which consistent with the definition germplasm. Therefore, it necessary define information, such as DNA methylation, histone modifications, ncRNAs, through generations, incorporate them into concept Germplasm should include not only but resources. Epigenetic variation arise from genetic, environmental, or stochastic factors. Genetic co‐determine phenotypic traits. It has been demonstrated inherited across generations aquatic animals. modification, ncRNAs are involved addressing environmental challenges, maintaining diversity, improving breeding strategies, combating inbreeding decline, age determination. future on important for conservation, development, utilization. This review proposes new theoretical framework elucidate place collects articles past 8 years explore inheritance Integrating enhances our understanding population dynamics, adaptation, evolutionary processes, thereby informing strategies enhancing aquaculture practices. By considering both resources, we address challenges facing more comprehensively.

Summary Cytosine methylation (mCG) is an important heritable epigenetic modification, yet its functions remain to be fully defined in crops. This study investigates mCG soybean following the loss‐of‐function mutation of two GmMET1 genes. We generated knockout mutants GmMET1s by CRISPR‐Cas9 and conducted comprehensive methylome transcriptome analyses. Our findings unravel functional redundancy s, with GmMET1b being more critically involved maintaining levels, complete both copies lethal. establish that genome‐wide levels scale aggregated expression . identify a set mCG‐regulated genes whose were quantitatively modulated upstream, body, or downstream mCG. Moreover, we find negatively regulated upstream body are enriched specific biological processes such as jasmonic acid metabolism. Notably, >80% differentially methylated (DMGs) also exist DMGs natural populations. Phenotypically, heterozygous for GmMET1a homozygous knockouts ( +/− −/− ) exhibited early flowering, which was inherited their selfed progeny +/+ otherwise normal growth development. either , slight reduction similar phenotypes compared wild type under conditions, showed enhanced tolerance cold drought stresses. Together, our results underscore highly orchestrated regulatory effects on gene soybean, dictates growth, development stress responses, implicating utility improvement better adaptability higher yield.

Inbreeding is the crossing of closely related individuals in nature or a plantation self-pollinating plants, which produces plants with high homozygosity. This process can reduce genetic diversity offspring and decrease heterozygosity, whereas inbred depression (ID) often viability. Inbred common animals has played significant role evolution. In review, we aim to show that inbreeding can, through action epigenetic mechanisms, affect gene expression, resulting changes metabolism phenotype organisms. particularly important plant breeding because profiles be linked deterioration improvement agriculturally characteristics.

Genetic diversity is a key factor for plant breeding. The birth of novel genic and genomic variants also crucial adaptation in nature. Therefore, the genomes almost all living organisms possess natural mutagenic mechanisms. Transposable elements (TEs) are major force driving genetic wild plants modern crops. relatively rare TE transposition activity during thousand-year crop domestication process has led to phenotypic many cultivated species. utilization mutagenesis by artificial transient acceleration their controlled mode an attractive foundation type called TE-mediated biological mutagenesis. Here, I focus on TEs as sources breeding discuss existing emerging transgene-free approaches activation plants.

Potato tuber skin is a protective corky tissue consisting of suberized phellem cells. Smooth-skinned varieties are characterized by clean, shiny appearance compared to the darker hue russeted potatoes. The rough cultivars desired, genetically inherited characteristic; however, unwanted russeting smooth-skinned often occurs under suboptimal growth conditions. involvement epigenetic modifiers in regulating smooth disorder was tested. We used smooth-skin commercial with and without three lines from breeding population segregating for russeting. Anatomically, russet showed similar characteristics, whether cause environmentally triggered or determined. old outer layers remain attached newly formed instead being sloughed off. Global DNA methylation analysis indicated significant reduction percentage 5-methylcytosine mature vs. immature skin. This true both lines. expression level selected methyltransferases reduced accordance. demethylase did not change between types age. Hence, more likely be achieved through passive demethylation loss methyltransferase activity.
