The Marchantia pangenome reveals ancient mechanisms of plant adaptation to the environment

This study analyzes the pangenome of Marchantia polymorpha to identify genetic features involved in plant adaptation to terrestrial environments, finding shared and lineage-specific genes with flowering plants.

Seagrass genomes reveal a hexaploid ancestry facilitating adaptation to the marine environment

This study presents chromosome-level genome assemblies of seagrass species and identifies ancient and recent genome duplication events linked to adaptation to marine environments.

Ocean currents drive the worldwide colonization of the most widespread marine plant, eelgrass (Zostera marina)

The paper reconstructs the colonization history of eelgrass using genomic data, showing trans-Pacific currents drove its spread and Atlantic populations arrived more recently with lower genetic diversity.

JGI Plant Gene Atlas: An updateable transcriptome resource to improve structural annotations and functional gene descriptions across the plant kingdom

The paper introduces the JGI Plant Gene Atlas, a resource that improves gene function annotations by analyzing transcript abundance across 18 species and 604 tissues, identifying 64,620 genes with unknown functions.

The western redcedar genome reveals low genetic diversity in a self-compatible conifer

The paper assembles the western redcedar genome and finds it has low genetic diversity, suggesting mechanisms like associative overdominance maintain genetic variation despite selfing.

Heritability and host genomic determinants of switchgrass root-associated microbiota in field sites spanning its natural range.

This study examines how host genetics and environmental factors shape root microbiota in switchgrass across its native range, finding heritable variation and local microbial recruitment.

Transcriptome and DNA methylome dynamics reveal differential characteristics of inflorescence development between two ecotypes in Panicum hallii

A comparative transcriptome and DNA methylome analysis of inflorescence between upland and lowland ecotypes reveals gene expression and DNA methylation variation underlying inflorescence divergence in Panicum hallii.

Multiplex knockout of trichome-regulating MYB duplicates in hybrid poplar using a single gRNA

A single gRNA targeting conserved sequences enabled efficient mutagenesis of a multigene family, resulting in trichomeless and triterpene-free poplar mutants.

The transcription factor Roc1 is a regulator of cellulose degradation in the wood-decaying mushroom Schizophyllum commune

This study identifies Roc1 as a key transcription factor regulating cellulose degradation in the wood-decaying fungus Schizophyllum commune through genomic and transcriptomic analyses.

The recent evolutionary rescue of a staple crop depended on over half a century of global germplasm exchange

The paper identifies a globally rare East African allele of RMES1 that conferred resistance to sugarcane aphids in Haitian sorghum, demonstrating the importance of global germplasm exchange for evolutionary rescue.

Novel insights into joint estimations of demography, mutation rate, and selection using UV sex chromosomes

This study examines how anisogamy influences genetic variation in moss using UV sex chromosomes, finding sex-biased mutation and selection but no model explaining observed diversity ratios.

The Ceratodon purpureus genome uncovers structurally complex, gene rich sex chromosomes

The paper compares genomes of male and female mosses to study sex chromosome evolution, finding gene-rich, non-degenerated UV sex chromosomes.

Hybridization history and repetitive element content in the genome of a homoploid hybrid, Yucca gloriosa (Asparagaceae)

This study investigates the hybridization history and transposon dynamics in Yucca gloriosa, a homoploid hybrid, using whole genome resequencing and mRNA-seq.

Assembly of a young vertebrate Y chromosome reveals convergent signatures of sex chromosome evolution

The paper assembles a young Y chromosome from threespine stickleback, revealing convergent evolutionary features with older sex chromosomes.

The Aquilegia genome: adaptive radiation and an extraordinarily polymorphic chromosome with a unique history

The paper presents the genome of Aquilegia coerulea and shows extensive allele sharing and introgression among species, with a unique chromosome evolutionary history.

The Sorghum bicolor reference genome: improved assembly and annotations, a transcriptome atlas, and signatures of genome organization

This paper improves the Sorghum bicolor reference genome, annotates it, and constructs a transcriptome atlas, revealing genomic features and gene expression patterns across developmental stages.
