Quorum sensing signals of the grapevine crown gall bacterium, Novosphingobium sp. Rr2-17: use of inducible expression and polymeric resin to sequester acyl-homoserine lactones
Background A grapevine crown gall tumor strain, Novosphingobium sp.strain Rr2-17 was previously reported to accumulate copious amounts of diverse quorum sensing signals during growth.Genome sequencing identified a single luxI homolog in strain Rr2-17, suggesting that it may encode for a AHL synthase with broad substrate range, pending functional va
