Evolution of monomodular all-helical receptor ligand-binding domains from bimodular ancestors

Jose A. Gavira, Míriam Rico‐Jiménez, Álvaro Ortega, Amalia Roca et autres

Bacterial chemotaxis is essential for environmental adaptation and host interaction. To this end, bacteria have evolved exceptionally broad chemosensory capacities, with few apparent constraints on ligand structure or size. These capacities are determined by the extraordinary diversity of chemoreceptor ligand-binding domains (LBDs), …

Acetylcholine signaling regulates osmotic stress adaptation in the phytopathogen Dickeya solani

Manuel J. Gilabert, Zulema Udaondo, Mario Cano‐Muñoz, Álvaro Ortega et autres

Plants impose strong selective pressures that shape both the composition and functional potential of plant microbiomes. The adaptation of plant-associated bacteria to their hosts relies on an extensive repertoire of signal transduction systems that sense plant-derived molecules and dynamically adjust bacterial physiology …

Auxin biosynthesis and signaling drive virulence and plant adaptation in Dickeya dadantii

Amalia Roca, Saray Santamaría‐Hernando, Zulema Udaondo, Juan J. Cabrera et autres

Plants and their associated bacteria engage in complex bidirectional interactions mediated by a diverse array of signaling molecules of both plant and microbial origin. Indole-3-acetic acid (IAA) is a central phytohormone regulating plant growth and development and is increasingly recognized as an …

Bacterial auxin catabolism as a driver of plant growth promotion and rhizosphere colonization fitness

Amalia Roca, Juan Gorts, Miguel A. Matilla

Inter-kingdom communication between plants and their associated microbiota is central to plant development and environmental adaptation. Indole-3-acetic acid (IAA) is the primary auxin in plants and regulates plant growth and development, while also modulating bacterial physiology and behavior. The concentration at which …

Harnessing Bacteriophages for Sustainable Crop Protection in the Face of Climate Change

Robert Czajkowski, Amalia Roca, Miguel A. Matilla

Crop pathogens represent a major challenge to global food security, causing over 40% yield losses in key crops and annual economic impacts estimated at up to US$290 billion. Microbial-based alternatives to synthetic agrochemicals offer sustainable solutions aligned with global initiatives like the …

Antibiotic‐producing plant‐associated bacteria, anti‐virulence therapy and microbiome engineering: Integrated approaches in sustainable agriculture

Amalia Roca, Laura Monge‐Olivares, Miguel A. Matilla

Plant health is crucial for maintaining the well-being of humans, animals and the environment. Plant pathogens pose significant challenges to agricultural production, global food security and ecosystem biodiversity. This problem is exacerbated by the impact of climate change, which is expected to …

Potential of the quorum‐quenching and plant‐growth promoting halotolerant Bacillus toyonensis AA1EC1 as biocontrol agent

Amalia Roca, Mónica Cabeo, Carlos Enguidanos, Fernando Martínez‐Checa et autres

The use of fertilizers and pesticides to control plant diseases is widespread in intensive farming causing adverse effects together with the development of antimicrobial resistance pathogens. As the virulence of many Gram-negative phytopathogens is controlled by N-acyl-homoserine lactones (AHLs), the enzymatic disruption …

The emerging role of auxins as bacterial signal molecules: Potential biotechnological applications

Tino Krell, Amalia Roca, Miguel A. Matilla

Microorganisms are exposed in their natural niches to a wide diversity of signal molecules. Specific detection of these signals results in alterations in microbial metabolism and physiology. Auxins like indole-3-acetic acid are key phytohormones that regulate plant growth and development. Nonetheless, auxin …

Microbial antibiotics take the lead in the fight against plant pathogens

Amalia Roca, Miguel A. Matilla

The plant microbiome is essential for plant fitness and health. Antibiotics produced by plant-associated bacteria have been shown to play an important role in protecting plant hosts against phytopathogens. Here, we highlight the strong biotechnological potential of (i) antibiotic producing plant-associated bacteria …
