The paper identifies a co-evolved peptide-GPCR system in Ustilago maydis that senses host entry by releasing a hidden peptide ligand from the secreted protein Pit2, promoting fungal proliferation.

The paper shows that the PPIP5K enzyme Asp1 produces opposite effects on fungal morphology and actin organization in different species, depending on the host cellular environment.

This study develops blue-light inducible gene expression switches to control morphogenesis and pathogenesis in Ustilago maydis, demonstrating their utility in regulating fungal invasion and tumor formation.

This study shows that endosomal mRNA transport coordinates mitochondrial bioenergetics in fungal hyphae, with Rrm4 essential for mitochondrial protein import and function.

This study investigates the metabolic and physiological effects of L-lysine on Synechocystis sp. PCC 6803, identifying key genes involved in Lys resistance and metabolic disruption.

This study identifies structural features of the MLLE domain in Rrm4 and reveals its role in recognizing short linear motifs for mRNA transport during endosomal trafficking.

The paper investigates the role of RNA interference in Arabidopsis by analyzing AGO and DCL mutants against various pathogens and a mutualist, revealing both positive and neutral effects on immunity and colonization.
