A non-genetic model of vascular shunts informs on the cellular mechanisms of formation and resolution of arteriovenous malformations

This study identifies EC volume changes as the key mechanism for AV shunt formation and regression, using a non-genetic model in mice.

A shift in the pathotype diversity and complexity of Phytophthora sojae, causal agent of root and stem rot of soybean, in Brazil

The paper reports a significant shift in the pathotype diversity and complexity of Phytophthora sojae in Brazil over a decade, highlighting the need for updated resistance breeding strategies.

Grapevine leaf MALDI-MS imaging reveals the localisation of a putatively identified sucrose metabolite associated to Plasmopara viticola development

The paper uses MALDI-MS imaging to localise a putatively identified sucrose metabolite associated with Plasmopara viticola infection in grapevine leaves.

Evolution of the quorum sensing systems in Pseudomonas aeruginosa can involve both loss of regulon function and network modulation

The paper examines 61 QS mutants of Pseudomonas aeruginosa to determine how mutations in the quorum sensing regulon affect virulence and social traits, finding that some mutations lead to loss of function while others modulate network activity.

Revealing the secrets beneath grapevine and Plasmopara viticola early communication: a picture of host and pathogen proteomes

This study examines grapevine and Plasmopara viticola proteome changes within the first 6 hours of infection to understand early host-pathogen communication mechanisms.

Monoclonal antibodies against cell wall chitooligomers as accessory tools for the control of cryptococcosis

This study develops monoclonal antibodies against chitooligomers that enhance antifungal efficacy against Cryptococcus neoformans in vitro and in a mouse model.

Endothelial cell invasiveness is controlled by myosin IIA-dependent inhibition of Arp2/3 activity

The paper identifies myosin IIA's role in inhibiting Arp2/3 activity to regulate endothelial tip cell protrusions during sprouting angiogenesis.

Spider mites escape bacterial infection by avoiding contaminated food

This study shows spider mites avoid bacterial-contaminated food and are susceptible to bacterial infections via feeding and spraying, suggesting avoidance behaviors are key to reducing infection risk.
