Label-free structural imaging of plant roots and microbes using third-harmonic generation microscopy

This study uses third-harmonic generation microscopy to image plant roots and microbes in their natural environment without labels.

CO2 Response Screen in Grass Brachypodium Reveals Key Role of a MAP-Kinase in CO2-Triggered Stomatal Closure

This study identifies a MAP-kinase, BdMPK5, as critical for CO2-induced stomatal closure in Brachypodium, using forward genetics and structural modeling.

Structure and Function of the Dot/Icm T4SS

This study constructs a nearly-complete model of the Legionella pneumophila Dot/Icm T4SS using subtomogram averaging and integrative modeling, revealing structural insights into six new components and their functional interactions.

Extensive plant use of exometabolites

The paper uses 13C-tracing to study plant uptake of exometabolites across multiple species, finding that uptake accounts for 23% of the carbon budget in Brachypodium distachyon and that some metabolites promote root growth.

Regulation of hair cell and stomatal size by a hair-cell specific peroxidase in the grass Brachypodium distachyon

This study identifies BdPOX, a peroxidase, as a regulator of hair cell and stomatal size in Brachypodium distachyon, showing its role in cell wall modification and epidermal function.

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.

Mechanically induced localization of SECONDARY WALL INTERACTING bZIP is associated with thigmomorphogenic and secondary cell wall gene expression

The paper identifies a bZIP transcription factor, SWIZ, involved in grass thigmomorphogenesis, showing its nuclear translocation after mechanostimulation and its role in regulating gene expression.

Identification of candidate susceptibility genes to Puccinia graminis f. sp. tritici in wheat

The paper identifies candidate susceptibility genes to wheat stem rust disease by analyzing gene expression changes in susceptible and resistant wheat genotypes and a non-host plant.

Deubiquitination of phosphoribosyl-ubiquitin conjugates by PDE domain-containing Legionella effectors

This paper identifies DupA and DupB as deubiquitinases that reverse PR-ubiquitination, a novel modification mediated by Legionella effectors, and shows their role in modulating host-pathogen interactions.

In vivo structure of the Legionella type II secretion system by electron cryotomography

The paper presents the first in situ structure of the Legionella T2SS using cryo-ET, revealing architectural similarities and differences with T4P and supporting the piston model for substrate extrusion.

Genome-wide scans of selection highlight the impact of biotic and abiotic constraints in natural populations of the model grass Brachypodium distachyon.

The paper uses genome-wide scans of selection to identify biotic and abiotic factors shaping genetic diversity in Brachypodium distachyon populations.

Structure of the Legionella Dot/Icm type IV secretion system in situ by electron cryotomography

The paper reports the in situ structure of the Legionella Dot/Icm T4BSS using electron cryotomography, revealing structural similarities to T4ASSs and highlighting type-specific features.
