The PIN2 ortholog in barley modifies root gravitropism and architecture without impacting the shoot

This study shows that knocking out PIN2 in barley alters root gravitropism and architecture without affecting shoot growth.

Dynamics of mRNA fate during light stress and recovery: from transcription to stability and translation

The paper investigates how mRNA stability, transcription, and translation change during light stress and recovery in Arabidopsis thaliana, finding transcript destabilisation during stress and stabilisation during recovery.

Drastic differential CRISPR-Cas9 induced mutagenesis influenced by DNA methylation and chromatin features

This study shows that chromatin features and DNA methylation significantly affect CRISPR-Cas9 mutagenesis efficiency and mutation profiles in Arabidopsis thaliana.

Limited consequences for loss of RNA-directed DNA methylation in Setaria viridis domains rearranged methyltransferase (DRM) mutants

This study examines the effects of losing RNA-directed DNA methylation in Setaria viridis by analyzing methylation patterns and gene expression in drm1ab mutants, finding limited morphological and transcriptional consequences.

Enzymes degraded under high light maintain proteostasis by transcriptional regulation in Arabidopsis

The paper shows that under high light stress in Arabidopsis, nuclear-encoded enzymes with increased degradation rates are compensated by transcriptional upregulation to maintain proteostasis, while plastid-encoded proteins rely on other mechanisms.

Stability of DNA methylation and chromatin accessibility in structurally diverse maize genomes

The paper assesses chromatin accessibility and DNA methylation in four structurally diverse maize genomes, revealing conservation of features with dynamic boundaries in unmethylated regions.

Applying cis-regulatory codes to predict conserved and variable heat and cold stress response in maize

The paper uses transcriptome profiling of maize under heat and cold stress to identify cis-regulatory elements and develop models predicting gene expression responses.

Genetic and epigenetic contributions to variation in transposable element expression responses to abiotic stress in maize

This study examines how genetic and epigenetic factors influence transposable element expression in maize under abiotic stress conditions.

Cis-regulatory elements within TEs can influence expression of nearby maize genes

The paper identifies TE insertions that influence gene expression in maize by disrupting or carrying accessible chromatin regions, showing TEs can create novel regulatory elements.

Optimization of multiplexed CRISPR/Cas9 system for highly efficient genome editing in Setaria viridis

This paper develops a multiplexed CRISPR/Cas9 system with Trex2 exonuclease to improve genome editing efficiency in Setaria viridis, achieving high mutation rates and MMEJ-mediated repair.

Targeted epigenomic changes to the maize methylome resulting from tissue culture

This study identifies targeted epigenomic changes in maize methylomes due to tissue culture, showing consistent gains and losses of DNA methylation across multiple independent lines.
