	IngentaConnect Similarly Organized Lysogeny Modules in Temperate Siphoviridae fr... (Site not responding. Last check: 2007-10-22)
		Temperate Siphoviridae from an evolutionarily related branch of low GC content gram-positive bacteria share a common genetic organization of lysogeny-related genes and the predicted proteins are linked by many sequence similarities.
		In all known temperate Siphoviridae from low GC content gram-positive bacteria the lysogeny module is flanked by the lysis module and the DNA replication module.
		With a larger database of phage sequences it might be possible to establish a genomics-based phage taxonomy and to retrace the evolutionary history of selected phage modules or individual phage genes.

		The structural gene cluster and the lysis module from lytic group II Streptococcus thermophilus bacteriophage phiSfi11 was compared to the corresponding region from other Siphoviridae.
		Sequence similarity was only found between phiSfi11 and Siphoviridae from gram-positive hosts and correlated with the evolutionary distance between the bacterial hosts.
		Our data are compatible with the hypothesis that the structural gene operon from Siphoviridae of the low G+C group of gram-positive bacteria is derived from a common ancestor.

		Lytic phages infective for marine Synechococcus are easily isolated from seawater, and many of these have been shown to be Myoviridae although some Siphoviridae and Podoviridae have also been isolated.
		We have been interested in lysogeny in Synechococcus because of the observation of seasonal variation in natural populations of Synechococcus in Tampa Bay (McDaniel et al, 2002).
		In addition to the common lytic cyanophages we have demonstrated lysogeny based on prophage induction in natural populations of Synechococcus in both Tampa Bay and the Gulf of Mexico (McDaniel et al, 2002, McDaniel and Paul, 2005).

		A virulent bacteriophage, designated PLgY, was detected from cultures of Lactococcus garvieae (formerly Enterococcus seriolicida) isolated from diseased yellowtail Seriola quinqueradiata.
		The phage had an isometric head measuring 50 to 60 nm, a thin flexible tail of 7 × 140-180 nm, and the genome consisting of double stranded DNA, indicating that PLgY is a member of the family Siphoviridae.

		Another scheme of classification denotes all phages in the set including lambda that can recombine with one another to yield infectious progeny as "lambdoid phages" (3).
		The phages classified this way are all dsDNA phages but not all are Siphoviridae.
		As far as is known, all lambdoid phages are of temperate phage lineage, though some of the known examples are defective for lysogeny.

		The major capsid proteins detected by electrophoresis were distinct in each family, with either 50, 33 and 24 kDa proteins or 30 and 25 kDa proteins for Siphoviridae phages, and 63 and 53 kDa proteins for Myoviridae phages.
