Cyanophage as 1. Cyanophage AS-1, which infects Synechococcus sp. The initial rate of adsorption was not significantly affected by light. Feb 24, 2006 · Previous experiments with cyanophage AS-1 and cyanobacteria Anacystis nidulans have provided some evidence that AS-1 may have a lysogenic life cycle in addition to the characterized lytic cycle. The type species for Cyanomyovirus of the family Myoviridae is Cyanophage AS-1, which was isolated from a waste stabilization pond, [12] and was also the first genus recognized. [14][3] Cyanophages generally have isometric hexagonal Aug 24, 2021 · This method enables direct investigation of key cyanophage genes, and its simplicity makes it adaptable to other ecologically relevant host-virus systems. 130 nm) polyhedral virus that caused the lysis of a marine photosynthetic picoflagellate, Micromonas pusilla (Prasinophyceae). [13] The tails have been observed as either contractile or noncontractile with lengths of 20 to 244 nm, widths of 15 to 23 nm, and a shrinking range of 93 nm. The structure of AS-1 resembles the T-even bacteriophage that replicate in Escherichia coli. The study gives insight into the effect of climate change on the interaction between cyanophage and cyanobacteria in freshwater ecosystems. However, at Na+ levels used ordinarily … AS-1L differs from the other strains of AS-1 by a shorter growth cycle, especially a shorter latent period, by the kinetics of inactivation by antiserum, and by a somewhat narrower pH scope of stability. elongatus PCC 6301 was grown under continuous light, 70% of cyanophage AS-1 were adsorbed within 15 min, and a maximum adsorption of 80% was reached after 20 min (Cséke and Farkas, 1979). In Synechococcus sp. The initial rate of adsorption was not significantly affected However, cells of strains 6907 and 6911 were lysed by cyanophage AS-1. May 1, 2011 · Thus, temperature is an important inducer for AS-1 conversion from lysogenic to lytic cycle and could have applications in terms of modulating cyanobacterial populations in freshwater aquatic environments. It was a large (ca. The effect of illumination on the extent and kinetics of the adsorption of cyanophage AS-1 to the blue-green alga (cyanobacterium) Anacystis nidulans was studied by using 32P-labeled phage. Cyanophage AS-1 was named after its two hosts Anacystis nidulans (now named Synechococcus sp. Results: In this study, the possible temperate A. elongatus strains PCC 6301 and PCC 7942. Jan 11, 2016 · Cyanophage AS-1 is a myovirus that infects closely related freshwater S. Several years later, a morphologically similar but larger (185 nm) virus (HVCV-1) was discovered that infected a Chlorella -like symbiont isolated from Hydra viridis (Meints et al. Burst size was decreased by dark incubation to 2% of that observed in the light Cyanophage AS-1, which infects Synechococcus sp. nidulans was treated with different concentrations of heavy metal-copper. . , 1981). IU 625) and S ynechococcus cedrorum. cells AS-1 cyanophage infection gradually inhibits the photosystem II mediated photosynthetic electron flow whereas the activity … Cyanophage AS-1, which infects Synechococcus sp. A comparison of the host range of this phage with the lipopolysaccharide composition of host and non-host cell walls suggests that lipopolysaccharides are involved in the adsorption process. Consequently the isolated cyanophage is to be looked at as a new strain of the cyanophage AS-1. IU 625 (Anacystis nidulans) and Synechococcus cedrorum, plays an important role in the environment, significantly altering the numbers of its hosts. The development cycle of the cyanophage AS-1 was studied in the host blue-green alga, Anacystis nidulans, under conditions that impair photosynthesis and under various light/dark regimes. Thus, temperature is an important inducer for AS-1 conversion from lysogenic to lytic cycle and could have applications in terms of modulating cyanobacterial populations in freshwater aquatic environments. Previous experiments with cyanophage AS-1 and cyanobacteria Anacystis nidulans have provided some evidence that AS-1 may have a lysogenic life cycle in addition to the characterized lytic cycle. , 1972). Under standard conditions of incubation the 16-h development cycle consisted of a 5-h eclipse period and an 8-h latent period. When S. Under standard conditions of incubation the 16-h development cycle consisted of a 5-h eclipse period and an 8-h … The type species is Cyanophage AS-1 isolated from waste stabilization pond and mainly infects Anacystis and Synechococcus (Safferman et al. These viruses are predominantly found in marine waters; however, some freshwater isolates have also been reported. ipm91k, fees, d1ktx5, 4chda, dlovp, fbib, 7wndv, d5zap, meyvd, 7puzu,
