Viral metagenomics reveals diverse virus-host interactions throughout the soil depth profile
mBio, 2023 Soil microbes play pivotal roles in global carbon cycling; however, the fundamental interactions between microbes and their infecting viruses remain unclear.

Fixed points and limit cycles in the population dynamics of lysogenic viruses and their hosts
, 2010 Starting with stochastic rate equations for the fundamental interactions between microbes and their viruses, we derive a mean field theory for the population dynamics of microbe-virus systems, including the effects of lysogeny. In the absence of lysogeny,

Frontiers in Microbiology, 2020 Prophages or prophage remnants are found in chromosomes of many bacterial strains and might increase the environmental fitness and/or virulence of their hosts.

Giant number fluctuations in microbial ecologies
, 2012 Statistical fluctuations in population sizes of microbes may be quite large depending on the nature of their underlying stochastic dynamics. For example, the variance of the population size of a microbe undergoing a pure birth process with unlimited ...

Epigenetics as a first exit problem
, 2001 We develop a framework to discuss stability of epigenetic states as first exit problems in dynamical systems with noise. We consider in particular the stability of the lysogenic state of the lambda prophage, which is known to exhibit exceptionally large ...

Frontiers in Ecology and Evolution, 2018 Phages have a major impact on microbial populations. In this work, we discuss how predation, transduction, lysogeny, and phage domestication lead to symbio-centric genomic interactions between bacteria and phages, ranging from antagonistic to mutualistic.

Lysogen stability is determined by the frequency of activity bursts from the fate‐determining gene
Molecular Systems Biology, 2010 The ability of living cells to maintain an inheritable memory of their gene‐expression state is key to cellular differentiation. Bacterial lysogeny serves as a simple paradigm for long‐term cellular memory.

Biochemical Studies of Lysogeny
Journal of Biological Chemistry, 1960 SUMMARY 1. The physical characteristics of X virus obtained from ultra- violet induction of Escherichia coli K12X have been compared with those of X virus obtained by infection of the sensitive host E. coli W-1485. No significant differences were observed, and it has been concluded that the present evidence supports the view that the X virus from ...
