T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, Volume 13, Issue 51, 14 September 2026.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, Volume 13, Issue 51, 14 September 2026.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

Activity and Silencing of Transposable Elements in C. elegans

DNA
Since the discovery of transposable elements (TEs) in maize in the 1940s by Barbara McClintock transposable elements have been described as junk, as selfish elements with no benefit to the host, and more recently as major determinants of genome structure

Retrotransposon evolution in diverse plant genomes

, 2000
Retrotransposon or retrotransposon-like sequences have been reported to be conserved components of cereal centromeres. Here we show that the published sequences are derived from a single conventional Ty3-gypsy family or a nonautonomous derivative.

Translocation of a 190-kb mitochondrial fragment into rice chromosome 12 followed by the integration of four retrotransposons

International Journal of Biological Sciences, 2005
A 190-kb mitochondrial DNA sequence interrupted by seven foreign DNA segments was identified in rice chromosome 12. This fragment is the largest mitochondrial fragment translocated into the rice nuclear genome.

Mutations in retrotransposon AtCOPIA4 compromises resistance to Hyaloperonospora parasitica in Arabidopsis thaliana

Genetics and Molecular Biology, 2010
Retrotransposons (RTEs) are a principal component of most eukaryotic genomes, representing 50%-80% of some grass genomes. RTE sequences have been shown to be preferentially present in disease resistance gene clusters in plants.

The Tnt1 retrotransposon escapes silencing in tobacco, its natural host

, 2021
Retrotransposons' high capacity for mutagenesis is a threat that genomes need to control tightly. Transcriptional gene silencing is a general and highly effective control of retrotransposon expression.

Reference‐Guided Chromosome‐Scale Genome Assembly With Insights on Population Genomics of the Atlantic Goliath Grouper (Epinephelus itajara), Islas del Rosario, Colombia

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We present a high‐quality chromosome‐level genome assembly and population genomic analysis of the critically endangered Goliath grouper (Epinephelus itajara) using PacBio HiFi and Illumina sequencing technologies. The 1.12 Gb genome assembly showed high contiguity and identified 22,692 protein‐coding genes, while comparative analyses revealed conserved

The Rise of Plant Pan‐Genomes: From Genome Variation to Predictive Breeding

Advanced Genetics, Volume 7, Issue 3, September 2026.
Plant pan‐genomics is shifting from genome variation discovery to understanding how diversity drives biological function and breeding value. Future advances will integrate SV/PAV, haplotype diversity, super pan‐genomes, pan‐omics, 3D genomics, and AI to transform genomic resources into predictive breeding strategies.
