Wild phage evolution Bacteria possess a diversity of highly specific defense mechanisms that evolve rapidly and account for large proportion bacterial genomes. These dynamics must be understood if therapy is to seriously considered clinical use. Hussain et al . studied set nearly clonal wild-caught Vibrio lentus hosts their found the segregated into two groups infected by different viruses (see Perspective Meaden Fineran). Puzzlingly, both host have same surface receptors. This apparent...
Interactions between bacteria and bacteriophage viruses (phages) are known to influence pathogen growth virulence, microbial diversity even biogeochemical cycling. Lytic phages in particular infect lyse their host cells, can therefore have significant effects on cell densities as well competitive dynamics within communities. Despite the impacts of lytic ecology evolution free-living communities, little is about role host-associated microbiomes. We set out characterize impact tomato...
Eukaryotic phytoplankton, also known as algae, form the basis of marine food webs and drive carbon sequestration. Algae must regulate their motility gravitational sinking to balance access light at surface nutrients in deeper layers. However, regulation remains largely unknown, especially motile species. Here, we quantify velocities according Stokes’ law diverse clades unicellular microalgae reveal cell size, density, nutrient dependency velocities. We identify a algal species, Tetraselmis...
ABSTRACT Optical density is a proxy of total biomass concentration and commonly used for measuring the growth bacterial cultures. However, there misconception that exponential optical equivalent to steady-state population growth. Many cells comprise culture individuals can differ from one another. Hallmarks are stable frequency distributions cellular properties over time, something alone cannot quantify. Using single-cell mass sensors paired with measurements, we explore when prevails in...
In North America, uncultivated, free-living grapevines (Vitis spp.) frequently grow alongside their cultivated counterparts, thus increasing the potential for exchange of microbiota. For this study, we used high-throughput sequencing (HTS) small RNAs to survey virus populations in Finger Lakes region New York State. Of 32 analyzed, 23 were vines, while remaining 9 commercially grown Vitis vinifera plants from same region. total, 18 (78.3%) tested positive grapevine asteroid mosaic-associated...
Although plasmids play an important role in biological evolution, the number of plasmid families well-characterized terms geographical distribution and evolution remains limited, especially archaea. Here, we describe first systematic study archaeal family, pT26-2 family. The in-depth analysis distribution, biogeography host-plasmid co-evolution patterns 26 integrated 3 extrachromosomal this family shows that they are widespread Thermococcales Methanococcales isolated from around globe but...
ABSTRACT Eukaryotic phytoplankton, also known as algae, form the basis of marine food webs and drive carbon sequestration when their biomass sinks to ocean floor. Algae must regulate vertical movement, determined by motility gravitational sinking, balance access light at surface nutrients in deeper layers. However, regulation sinking velocities remains largely unknown, especially motile species. Here, we directly quantify single-cell masses volumes calculate according Stokes’ law diverse...
