autoinducida
Autoinducida is a term used in biology to describe processes or states that are initiated by signals produced within an organism or microbial population, without the need for external cues. In the context of quorum sensing, bacteria secrete small signaling molecules called autoinducers. As cell density increases, the concentration of these autoinducers rises until it reaches a threshold that triggers a coordinated change in gene expression across the population, a phenomenon known as autoinduction.
Molecular mechanisms vary among organisms. In Gram-negative bacteria, autoinducers such as acyl-homoserine lactones are synthesized by
Applications and implications of autoinduction include understanding and potentially controlling bacterial pathogenicity by disrupting autoinducer production
