A GH81-type β-glucan-binding protein facilitates colonization by mutualistic fungi in barley

This study identifies a β-glucan-binding protein in barley that facilitates colonization by beneficial fungi and influences resistance to pathogens.

Interplay of EXO70 and MLO proteins modulates trichome cell wall composition and powdery mildew susceptibility

This study shows that EXO70 and MLO proteins interact to regulate trichome cell wall composition, affecting powdery mildew resistance in Arabidopsis.

A conserved enzyme of smut fungi facilitates cell-to-cell movement in the plant bundle sheath

The paper identifies Erc1 as a conserved enzyme in smut fungi that enables cell-to-cell movement in plant bundle sheath cells, contributing to virulence across different host species.

Explosive seed dispersal depends on SPL7 to ensure sufficient copper for localized lignin deposition via laccases

The paper identifies SPL7 as essential for copper accumulation in Arabidopsis relative fruit valves, enabling laccase activity required for asymmetric lignin deposition and explosive seed dispersal.

Fungi hijack a plant apoplastic endoglucanase to release a ROS scavenging β-glucan decasaccharide to subvert immune responses

The paper identifies a fungal extracellular polysaccharide matrix component, β-1,3;1,6-glucan decasaccharide, released by a plant enzyme that suppresses plant immunity and enhances fungal colonization.

Modular biosynthesis of plant hemicellulose and its impact on yeast cells

This study engineers yeast to produce tunable plant hemicellulose polysaccharides using chimeric CSLA enzymes, showing growth compatibility and variable cell size modulation.

Degradation of mixed-linkage (1,3;1,4)-β-D-glucan in maize is mediated by the CAL1 licheninase

The paper identifies CAL1 as a licheninase responsible for degrading mixed-linkage (1,3;1,4)-β-D-glucan in maize, showing its role in regulating MLG content and saccharification efficiency.

Inhibition of Invasive Salmonella by Orally Administered IgA and IgG Monoclonal Antibodies

This study shows orally administered IgA and SIgA monoclonal antibodies can reduce Salmonella Typhimurium uptake in Peyers patches, while IgG is less effective, highlighting the need for improved formulations to sustain mAb activity in the gut.

Genetic dissection of cell wall defects and the strigolactone pathway in Arabidopsis.

The paper investigates the interaction between secondary wall defects and strigolactone biosynthesis in Arabidopsis, showing that SLs suppress irx syndrome phenotypes in xylan and cellulose mutants but not in primary wall mutants.

Growth- and stress-related defects associated to wall hypoacetylation are strigolactone-dependent

The paper shows that strigolactone biosynthesis compensates for wall hypoacetylation defects in Arabidopsis, suggesting SL pathway activation is a response to wall structural changes.

Identification of an arabinopyranosyltransferase from Physcomitrella patens involved in the synthesis of the hemicellulose xyloglucan

The paper identifies an arabinopyranosyltransferase from Physcomitrella patens involved in xyloglucan synthesis and shows its role in restoring plant growth in mutants.
