Cells of colonize the light organ of , providing the squid bioluminescence in exchange for nutrients and protection. The bacteria encounter DNA-rich mucus throughout their transition to a symbiotic lifestyle, leading us to hypothesize a role for nuclease activity in the colonization process. In support of this, we detected abundant extracellular nuclease activity in growing cells of .

Counterclockwise rotation of the flagellum promotes biofilm initiation in .

Unlabelled: Motility promotes biofilm initiation during the early steps of this process: microbial surface association and attachment. Motility is controlled in part by chemotaxis signaling, so it seems reasonable that chemotaxis may also affect biofilm formation. There is a gap, however, in our understanding of the interactions between chemotaxis and biofilm formation, partly because most studies analyzed the phenotype of only a single chemotaxis signaling mutant, e.

Emerging nitrogen-fixing cyanobacteria for sustainable cotton cultivation.

Amid growing environmental concerns and the imperative for sustainable agricultural practices, this study examines the potential of nitrogen-fixing cyanobacteria as biofertilizers, particularly in cotton cultivation. The reliance on synthetic nitrogen fertilizers (SNFs), prevalent in modern agriculture, poses significant environmental challenges, including greenhouse gas emissions and water system contamination. This research aims to shift this paradigm by exploring the capacity of cyanobacteria as a natural and sustainable alternative.

Challenging the term symbiosis in plant-microbe associations to create an understanding across sciences.

Scientific progress relies on clear and consistent definitions for effective communication and collaboration. The term "symbiosis" in the context of plant-microbe associations suffers from diverse interpretations, leading to ambiguity in classification of these associations. This review elaborates on the issue, proposing an inclusive definition as well as a keyword.
