Structural transitions in the GTP cap visualized by cryo-EM of catalytically inactive microtubules

The paper uses cryo-EM to visualize the structure of GTP-bound microtubules, revealing an expanded lattice and closed seam that stabilize the GTP cap.

Barley RIC157 is involved in RACB-mediated susceptibility to powdery mildew

This study identifies RIC157 as a RACB-interacting protein that enhances barley susceptibility to powdery mildew by facilitating fungal penetration.

ROP INTERACTIVE PARTNER b interacts with RACB and supports fungal penetration into barley epidermal cells

The paper identifies RIPb as a downstream interactor of RACB in barley that enhances susceptibility to powdery mildew fungus by localizing to microtubules and the plasma membrane during haustoria formation.

Barley ROP-INTERACTIVE PARTNER-a organizes into RAC1- and MICROTUBULE-ASSOCIATED ROP-GTPASE ACTIVATING PROTEIN 1-dependent membrane domains

The paper identifies RIPa's interaction with ROPs and shows it forms RAC1-dependent membrane domains regulated by microtubules and MICROTUBULE-ASSOCIATED ROP-GTPASE ACTIVATING PROTEIN 1.

A Barley Powdery Mildew Fungus Non-Autonomous Retrotransposon Encodes a Peptide that Supports Penetration Success on Barley

This study identifies a retrotransposon-derived peptide from the barley powdery mildew fungus that interacts with a host GTPase to manipulate microtubule organization and aid pathogen entry.
