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

open access: yesAdvanced 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.

Evolutionary history of Oryza sativa LTR retrotransposons: a preliminary survey of the rice genome sequences [PDF]

open access: yes, 2004
Background LTR Retrotransposons transpose through reverse transcription of an RNA intermediate and are ubiquitous components of all eukaryotic genomes thus far examined.

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

open access: yesEcology 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

LTR-retrotransposons in plants: Engines of evolution

open access: yes, 2017
LTR retrotransposons are the most abundant group of transposable elements (TEs) in plants. These elements can fall inside or close to genes, and therefore influence their expression and evolution.

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

open access: yesAdvanced 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.

Chromosome‐level genome and methylome of vine tea suggest roles for tandem duplication and CHH hypomethylation in high dihydromyricetin accumulation

open access: yesiMetaOmics, Volume 3, Issue 3, September 2026.
A chromosome‐level genome assembly and single‐base resolution methylome of vine tea (Nekemias grossedentata) reveal that lineage‐specific tandem duplications of dihydromyricetin (DHM) biosynthetic genes (NgCHS and NgF3′5′ H) have expanded their copy numbers, providing the genetic basis for high DHM flux.

The afterlife of a horizontally transferred gene: Expansion and functional diversification of a C1A peptidase in wild Hordeum species

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Horizontal gene transfer (HGT) can accelerate plant adaptation, but the evolutionary fate of newly acquired nuclear genes is often unclear. Here, we analyzed a papain‐like cysteine peptidase horizontally transferred from Panicoideae to wild Hordeum (Poaceae). Using chromosome‐level assemblies of 21 diploid Hordeum species, we assessed presence/

MOESM5 of Nested plant LTR retrotransposons target specific regions of other elements, while all LTR retrotransposons often target palindromes and nucleosome-occupied regions: in silico study

open access: yes, 2019
Additional file 5. Nucleosome occupancy prediction counted for Ty3/gypsy or Ty1/copia superfamilies members detected as nested or non-nested LTR retrotransposons in this ...

High‐density mutation tracks are associated with proton‐beam irradiation patterns in Sorghum bicolor

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Induced mutagenesis is a cornerstone of crop functional genomics, yet the extent to which distinct radiation sources reshape the spatial distribution of mutations remains difficult to evaluate in reduced‐representation datasets. Here, we analyze a published genotyping‐by‐sequencing (GBS) panel (192,040 loci) to compare proton‐beam and gamma ...

Systematic prioritization of candidate genes in camptothecin biosynthesis using multi‐omics and deep learning

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Camptothecin (CPT), a plant‐derived monoterpene indole alkaloid first identified in Camptotheca acuminata, is a drug precursor widely used for cancer chemotherapeutics. However, the full set of genes responsible for CPT biosynthesis remains unclear, hindering efforts to elucidate the complete pathway or establish biosynthetic production of CPT
