Dissecting genetic correlation and pleiotropy through a genetic cross

This paper introduces a method using genetic crosses to assess developmental bias and genetic correlation stability across conditions.

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.

Dynamics of expression variability underpin retention of small-scale vs. whole-genome duplicates

The paper examines expression variability in duplicated genes to understand retention mechanisms of small-scale and whole-genome duplicates.

Breeding of microbiomes conferring salt tolerance to plants

This study breeds microbiomes that confer salt tolerance to plants by selecting for beneficial microbial communities, showing increased seed weight and reduced sodium concentration in treated plants.

Does genetic variation in controlled experiments predict phenology of wild plants?

The paper investigates whether genetic variation in flowering and germination timing from controlled experiments predicts phenology in wild Arabidopsis thaliana.

Genotype by environment interactions in gene regulation underlie the response to soil drying in the model grass Brachypodium distachyon

The paper identifies genotype by environment interactions in gene regulation in Brachypodium distachyon under soil drying conditions, revealing conserved and variable gene regulatory networks.

Plant nutritional and metabolic responses to drought and elevated CO2 revealed by machine learning-enabled non-targeted metabolomics

The paper uses metabolomics and machine learning to study how drought and elevated CO2 affect nutrient dynamics in Brachypodium distachyon.

Does domestication trade-off stress tolerance for leaf growth? A search for evidence across eight Pooideae grass species

The paper examines trade-offs between domestication and drought response in leaf growth across eight Pooideae grass species using machine learning to analyze leaf cell kinematics.

Revisiting regulatory decoherence and phenotypic integration: accounting for temporal bias in co-expression analyses

The paper shows that population-level co-expression analyses in rice under temperature stress are biased due to regulatory saturation, but temporal correlations can reliably detect transient regulatory activity.

Evolution and functional dynamics of dehydrins in model Brachypodium grasses

The paper studies dehydrin genes in Brachypodium species, identifying their genomic organization, expression patterns, and functional roles in drought tolerance across different ecotypes.
