A Conserved Microbial Motif ‘Traps’ Protease Activation in Host Immunity
Sabale, Mugdha; Di Pietro, Antonio; Redkar, Amey (Cell Press, 2019)A recent study (Misas-Villamil et al., Nat. Commun., 2019) reveals that Pit2, an apoplastic effector of the corn smut fungus Ustilago maydis, contains an embedded motif of 14 amino acids that binds to and inhibits plant ... -
A PR-1-like Protein of Fusarium oxysporum Functions in Virulence on Mammalian Hosts
Prados Rosales, Rafael; Roldán-Rodríguez, Raquel; Serena, Carolina; Sánchez López-Berges, M.; Guarro, Josep; Martínez-del-Pozo, Álvaro; Di Pietro, Antonio (American Society for Biochemistry and Molecular Biology Online, 2012)The pathogenesis-related PR-1-like protein family comprises secreted proteins from the animal, plant, and fungal kingdoms whose biological function remains poorly understood. Here we have characterized a PR-1-like protein, ... -
Análisis molecular de la patogénesis en Fusarium oxysporum
González Roncero, M.I.; Rispail, Nicolás; Martínez Rocha, A.L.; Córdoba Cañero, D.; Martín-Urdíroz, M.; Martínez Aguilera, E.; Pérez Nadales, Elena; Prados Rosales, Rafael; Sánchez López-Berges, M.; Di Pietro, Antonio; Ruiz Roldán, Carmen; Pareja Jaime, Y.; Hera Díaz de Liaño, María Concepción de la (Universidad de Córdoba, 2009)El proceso de infección del hongo Fusarium oxysporum es complejo y requiere algunos mecanismos bien regulados: 1) el reconocimiento de señales de la planta, 2) la adhesión a la superficie de la raíz y la diferenciación ... -
Fusarium oxysporum Casein Kinase 1, a Negative Regulator of the Plasma Membrane H+-ATPase Pma1, Is Required for Development and Pathogenicity
Mariscal, Melani; Miguel Rojas, Cristina de; Hera, Concepción; Fernandes, Tânia R.; Di Pietro, Antonio (MDPI, 2022)Like many hemibiotrophic plant pathogens, the root-infecting vascular wilt fungus Fusarium oxysporum induces an increase in the pH of the surrounding host tissue. How alkalinization promotes fungal infection is not fully ... -
HapX-Mediated Iron Homeostasis Is Essential for Rhizosphere Competence and Virulence of the Soilborne Pathogen Fusarium oxysporum
Sánchez López-Berges, M.; Capilla, Javier; Turrà, David; Schafferer, Lukas; Matthijs, Sandra; Jöchl, Christoph; Cornelis, Pierre; Guarro, Josep; Haas, Hubertus; Di Pietro, Antonio (ASPB, 2012)Soilborne fungal pathogens cause devastating yield losses and are highly persistent and difficult to control. During the infection process, these organisms must cope with limited availability of iron. Here we show that the ... -
How alkalinization drives fungal pathogenicity
Ribeiro Fernandes, Tânia Alícia; Segorbe, David; Prusky, Dov; Di Pietro, Antonio (Public Library of Science, 2017)pH governs most, if not all, processes of life. In fungi, ambient pH acts as a potent regulator of growth and development [1]. Studies conducted primarily in the 2 model organisms Saccharomyces cerevisiae and Aspergillus ... -
Hyphal Growth of Phagocytosed Fusarium oxysporum Causes Cell Lysis and Death of Murine Macrophages
Schäfer, Katja; Bain, Judith M.; Di Pietro, Antonio; Gow, Neil A. R.; Erwig, Lars P. (PLOS, 2014)Fusarium oxysporum is an important plant pathogen and an opportunistic pathogen of humans. Here we investigated phagocytosis of F. oxysporum by J774.1 murine cell line macrophages using live cell video microscopy. Macrophages ... -
Marchantia polymorpha model reveals conserved infection mechanisms in the vascular wilt fungal pathogen Fusarium oxysporum
Redkar, Amey; Gimenez Ibanez, Selena; Sabale, Mugdha; Zechmann, Bernd; Solano, Roberto; Di Pietro, Antonio (Wiley, 2021)How co-evolution has shaped the interaction between plants andtheir associated microbes remains a central question in organis-mic interactions (Bonfante & Genre, 2010; Delaux & Schor-nack, 2021). Plants have evolved a ... -
Murine Model for Fusarium oxysporum Invasive Fusariosis Reveals Organ-Specific Structures for Dissemination and Long-Term Persistence
Schäfer, Katja; Di Pietro, Antonio; Gow, Neil A. R.; MacCallum, Donna (PLOS, 2014)The soil-borne plant pathogen Fusarium oxysporum causes life-threatening invasive fusariosis in immunocompromised individuals. The mechanism of infection in mammalian hosts is largely unknown. In the present study we show ... -
Plant Defensins NaD1 and NaD2 Induce Different Stress Response Pathways in Fungi
Dracatos, Peter M.; Payne, Jennifer; Anderson, Marilyn A.; Plummer, Kim M.; Di Pietro, Antonio (MDPI, 2016)Nicotiana alata defensins 1 and 2 (NaD1 and NaD2) are plant defensins from the ornamental tobacco that have antifungal activity against a variety of fungal pathogens. Some plant defensins interact with fungal cell wall ... -
Targeting Iron Acquisition Blocks Infection with the Fungal Pathogens Aspergillus fumigatus and Fusarium oxysporum

Utilizing in vitro neutrophil killing assays and a model of ... -
The Gal4-Type Transcription Factor Pro1 Integrates Inputs from Two Different MAPK Cascades to Regulate Development in the Fungal Pathogen Fusarium oxysporum
Palos-Fernandez, Rafael; Turra, David; Di Pietro, Antonio (MDPI, 2022)Mitogen-activated protein kinase (MAPK) signaling pathways control fundamental aspects of growth and development in fungi. In the soil-inhabiting ascomycete Fusarium oxysporum, which causes vascular wilt disease in more ... -
