Prokaryotes and eukaryotes secrete extracellular vesicles (EVs) into the surrounding milieu to preserve and transport elevated concentrations of biomolecules across long distances. EVs encapsulate metabolites, DNA, RNA, and proteins, whose abundance and composition fluctuate depending on environmental cues. EVs are involved in eukaryote-to-prokaryote communication owing to their ability to navigate different ecological niches and exchange molecular cargo between the two domains.

Extracellular-membrane vesicles (EMVs) are spherical buds of the extracellular membrane, commonly produced by Gram-negative bacteria, known to mediate intricate inter-kingdom communication. In this context, comprehensive research dissecting the role of EMVs in one of the most complex nature-occurring molecular dialogues, rhizobium-legume symbiosis, has been so far neglected. During the different stages of the symbiotic process, rhizobia and their host plants establish a very specific and controlled intercellular trafficking of signal molecules.

Rhizobia are a group of soil proteobacteria that are able to establish a symbiotic interaction with legumes. These bacteria are capable to fix atmospheric nitrogen into ammonia within specific plant root organs called nodules. The rhizobia-legume interaction is established by a complex molecular dialogue that starts with flavonoids exudated by the plant roots.

Acidovorax citrulli is one of the most important pathogens of cucurbit crops, mainly melon and watermelon. Although A. citrulli is able to infect all aerial parts of the plant, fruits are highly sensitive to the bacterium.

Introduction: The establishment of the rhizobium-legume nitrogen-fixing symbiosis relies on the interchange of molecular signals between the two symbionts. We have previously studied by RNA-seq the effect of the symbiotic regulators NodD1, SyrM, and TtsI on the expression of the symbiotic genes (the regulon) of HH103 upon treatment with the isoflavone genistein. In this work we have further investigated this regulatory network by incorporating new RNA-seq data of HH103 mutants in two other regulatory genes, and .
