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), …

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 …

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 …

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 …

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 …

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 …

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 …
