Summary Hybrid potato breeding offers a promising solution to tackle the challenges in breeding. However, most diploids are self‐incompatible (SI), which hinders development of inbred lines. S‐locus inhibitor ( Sli ) is ‘master key’ gene capable conferring self‐compatibility (SC) SI diploids, yet regulatory mechanism underlying its male gamete‐specific expression remains unclear, limiting potential. This study has uncovered that miniature inverted‐repeat transposable element (Mi‐549) within promoter can affect methylation pattern promoter, thereby regulating pollen‐specific as well SC phenotype diploids. We delved into origin Mi‐549 Petota and found was likely acquired fortuitously wild Solanum lesteri but not favored during domestication, probably due asexual propagation nature potato. Although impacts on selected, screening identified three novel accessions belong S. , neocardenasii stenotomum enrich germplasm pool associated with stress pest resistance hold significant value for applications.

SUMMARY Environmental stimuli can induce the transfer of chloroplast DNA to nuclear genome, resulting in nuclear‐integrated plastid DNAs (NUPTs). However, their role plant adaptability remains unclear. Species within Caryophyllales order, known for adaptation extreme environments, provide an ideal model studying evolutionary dynamics and functions NUPTs. In this study, we analyzed NUPTs 24 species investigate evolution regulatory roles gene expression, particularly response environmental stimuli. We found significant interspecies variation NUPT abundance, ranging from 566 insertions Amaranthus cruentus 3585 Beta vulgaris , with sizes spanning 100 bp over kb. Approximately 62% were inserted last 20 million years, while some exhibit insertion peaks dating back 49 years. presence/absence polymorphisms six related suggest that deletions are dynamic processes influenced by phylogeny. predominantly integrate into intergenic regions but also insert genes promoters, certain acting as hotspots. Notably, introduce numerous environmental‐responsive cis ‐acting elements promoter regions. Genes promoters significantly enriched response. Further luciferase assays Spinacia oleracea demonstrated regulate expression responses, indicating potential adaptive evolution. Overall, our study provides insights influence on function

Transposon is the main component of eukaryotic genome, and more plant genome data show that transposons are diverse in regulating structure, variation, function evolution, with different transposition mechanisms genome. Hybridization polyploidy play an important role promoting speciation recent studies have shown usually accompanied by expansion transposons, which affect size structure polyploid plants. Transposons can insert into genes intergenic regions, resulting great differences overall closely related species, it also capture gene segments to increase copy number genes. In addition, influence epigenetic modification state regulate expression gene, while phenotype, biological abiotic stress response regulated transposons. Overall, especially adaptation evolution.

Introduction The rice improvement process, driven by modern breeding techniques, represents the second revolutionary advancement in agronomic traits, following domestication. Advances pan-genomes and enhanced capacity for analyzing structural variations have increasingly highlighted their role genetic improvement. Transposable element (TE) variants been previously reported to influence genomic diversity during domestication, but contribution from landraces improved varieties remains unclear. Methods Here, we combined a high-quality pan-TE variation map, transcriptome profiles, phenotypic data 100 92 investigate of TE rice. Results total number length were significantly greater than those landraces, particularly Ty3-retrotransposons, LTR Copia Helitron elements. Comparing varieties, 4,334 selective TEs detected within or near 3,070 genes that enriched basic metabolism development stress resistance. Among 14,076 differentially expressed between two groups, expression level 3,480 (24.7%) associated with variations. Combining haplotype analysis, demonstrated potential patterns how affect gene thereby participate important traits Discussion Collectively, our results highlight contributions shaping basis will facilitate exploration superior advance molecular efforts

Transposable elements (TEs) constitute a large portion of many plant genomes and play important roles in regulating gene expression driving genome evolution crop domestication. Despite advances understanding the functions mechanisms TEs, comprehensive review their integrated knowledge cutting-edge biotechnological applications TEs is still needed. We provide thorough overview that connects discoveries, mechanisms, technologies associated with TEs. discuss identification function driven by functional genomics, epigenetic regulation utilization active genomics engineering. In summary, expanding application will be beneficial to breeding synthetic biology future.
