Also, with thousands of bacterial genomes sequenced, now scientists use computers to look for DNA sequence matches to known quorum-sensing genes (see Whiteboard video on Bioinformatics). These analyses show that it is very common for bacteria to possess quorum-sensing systems and, moreover, to use multiple autoinducers and multiple receptors for quorum sensing.
