High-density CRISPRi screens reveal adaptive transcriptional gradients in cyanobacteria

This study uses CRISPRi screens to identify transcriptional gradients in Synechococcus sp. PCC 7002 that improve growth under cold monochromatic light conditions.

Catabolic pathway acquisition by soil pseudomonads readily enables growth with salicyl alcohol but does not affect colonization of Populus roots

The paper transfers a catabolic pathway for salicyl alcohol in Pseudomonas soil isolates, showing it enables rapid catabolism but does not confer a fitness advantage in rhizosphere competition.

Decoding the chemical language of Suillus fungi: genome mining and untargeted metabolomics uncover terpene chemical diversity

This study combines genomics and metabolomics to identify terpene diversity in Suillus fungi, revealing metabolites involved in fungal communication and host interactions.

A phosphorylation-deficient ribosomal protein eS6 is largely functional in Arabidopsis thaliana, rescuing mutant defects from global translation and gene expression to photosynthesis and growth

This study shows that a phosphorylation-deficient eS6 isoform in Arabidopsis thaliana largely rescues mutant defects in growth, photosynthesis, and gene expression, with minor residual issues.

Functional analysis of Salix purpurea genes support roles for ARR17 and GATA15 as master regulators of sex determination

This study functionally characterizes candidate sex determination genes in Salix purpurea using Arabidopsis, supporting ARR17 and GATA15 as master regulators and identifying downstream transcription factors.

Fungal antibiotics control bacterial community diversity in the cheese rind microbiome

This study shows that fungal antibiotics, specifically pseurotins, regulate bacterial community diversity in cheese rind microbiomes by controlling bacterial abundance and composition.

An intein-mediated split-nCas9 system for base editing in plants

This paper develops a split-nCas9 system using intein-mediated reassembly for efficient base editing in plants.

Plant-based biosensors for detecting CRISPR-mediated genome engineering

This study develops plant-based biosensors to detect CRISPR/Cas tools in real-time, demonstrating their effectiveness in detecting various CRISPR functions in multiple plant species.

Critical Assessment of Metaproteome Investigation (CAMPI): a Multi-Lab Comparison of Established Workflows

CAMPI evaluates metaproteomic workflows across labs, finding sample processing drives peptide variability while workflows yield similar functional profiles.
