Signal transduction and sporulation in Bacillus subtilis: heterologous phosphorylation of Spo0A, a sporulation initiation gene product.

abstract：:Microvesicles (MVs) serve as vectors of nucleic-acid dissemination and are important mediators of intercellular communication. However, the functionality of packaged nucleic acids on recipient cells following transfer of MV cargo has not been clearly elucidated. This limitation is attributed to a lack of methodology a...
