Genomics and adaptive divergence of the allopolyploid grass Brachypodium hybridum in a pangenotypic framework

This study analyzes the origins and evolutionary dynamics of the allopolyploid grass Brachypodium hybridum using whole-genome sequencing and phylogenomic approaches, revealing three independent allopolyploidization events and subgenome-specific evolutionary patterns.

Multidimensional host-associated diversification in natural Festuca_Epichloe festucae symbioses across the Iberian Peninsula

The paper characterizes host-associated diversification in Epichloe festucae symbioses across Iberian Festuca species, revealing host-driven genetic and chemical differentiation.

From tiny to massive: exploring genome evolution in the model 1 grass genus Brachypodium

This study presents chromosome-level assemblies of two perennial Brachypodium species, revealing genomic features like polyploidy and transposable element dynamics that shaped genome evolution.

Genic and phylogenomic discordances reveal conflicting hybridization episodes in temperate Loliinae grasses

This study reveals hybridization episodes in Loliinae grasses using phylogenomic data, showing lineage-specific hybridization rates and discordances between nuclear and plastome trees.

CollapsedChrom: resolving the assembly of collapsed chromosomal segments in polyploid genomes of the model grass genus Brachypodium

The paper develops a method to resolve collapsed chromosomal segments in polyploid Brachypodium genomes, improving assembly quality and capturing genomic architecture.

A Palearctic divide, niche conservatism and host-fungal endophyte interactions shaped the phylogeography of the grass Brachypodium sylvaticum

This study investigates the phylogeography of Brachypodium sylvaticum and its fungal symbiont Epichloe sylvatica, revealing co-divergence, niche conservatism, and geographic isolation as key factors in lineage splitting.

Exploring genomic diversity and reproductive strategies in three expansion phases of the superdominant Brachypodium rupestre in high mountain grasslands

This paper investigates the taxonomy and nomenclature of three annual Brachypodium species using morphological analysis and nomenclatural review, leading to synonymy and conservation proposals.

Genomic and evolutionary evidence for drought adaptation of grass allopolyploid Brachypodium hybridum

This study shows how polyploidy in Brachypodium hybridum enhances drought adaptation through genomic legacies and subgenome expression biases.

Nuclear phylogenomics of grasses (Poaceae) supports current classification and reveals repeated reticulation

This study constructs a nuclear phylogeny of grasses using genome-scale data, showing agreement with plastome phylogeny and evidence for repeated reticulation events.

Evolution and functional dynamics of dehydrins in model Brachypodium grasses
