text: "Mutations are the raw material of evolution and come in many different flavors.
Point mutations change a single letter in the DNA sequence, while copy number
mutations like duplications or deletions add or remove many letters of the DNA
sequence simultaneously. Each type of mutation exhibits specific properties like
its rate of formation and reversal. \r\nGene expression is a fundamental phenotype
that can be altered by both, point and copy number mutations. The following thesis
is concerned with the dynamics of gene expression evolution and how it is affected
by the properties exhibited by point and copy number mutations. Specifically,
we are considering i) copy number mutations during adaptation to fluctuating environments
and ii) the interaction of copy number and point mutations during adaptation to
constant environments. "

text: Tight control over protein degradation is a fundamental requirement for cells
to respond rapidly to various stimuli and adapt to a fluctuating environment.
Here we develop a versatile, easy-to-handle library of destabilizing tags (degrons)
for the precise regulation of protein expression profiles in mammalian cells by
modulating target protein half-lives in a predictable manner. Using the well-established
tetracycline gene-regulation system as a model, we show that the dynamics of protein
expression can be tuned by fusing appropriate degron tags to gene regulators.
Next, we apply this degron library to tune a synthetic pulse-generating circuit
in mammalian cells. With this toolbox we establish a set of pulse generators with
tailored pulse lengths and magnitudes of protein expression. This methodology
will prove useful in the functional roles of essential proteins, fine-tuning of
gene-expression systems, and enabling a higher complexity in the design of synthetic
biological systems in mammalian cells.

text: With the recent publication by Silpe and Bassler (2019), considering phage
detection of a bacterial quorum-sensing (QS) autoinducer, we now have as many
as five examples of phage-associated intercellular communication (Table 1). Each
potentially involves ecological inferences by phages as to concentrations of surrounding
phage-infected or uninfected bacteria. While the utility of phage detection of
bacterial QS molecules may at first glance appear to be straightforward, we suggest
in this commentary that the underlying ecological explanation is unlikely to be
simple.

text: Mathematical models have been used successfully at diverse scales of biological
organization, ranging from ecology and population dynamics to stochastic reaction
events occurring between individual molecules in single cells. Generally, many
biological processes unfold across multiple scales, with mutations being the best
studied example of how stochasticity at the molecular scale can influence outcomes
at the population scale. In many other contexts, however, an analogous link between
micro- and macro-scale remains elusive, primarily due to the challenges involved
in setting up and analyzing multi-scale models. Here, we employ such a model to
investigate how stochasticity propagates from individual biochemical reaction
events in the bacterial innate immune system to the ecology of bacteria and bacterial
viruses. We show analytically how the dynamics of bacterial populations are shaped
by the activities of immunity-conferring enzymes in single cells and how the ecological
consequences imply optimal bacterial defense strategies against viruses. Our results
suggest that bacterial populations in the presence of viruses can either optimize
their initial growth rate or their population size, with the first strategy favoring
simple immunity featuring a single restriction modification system and the second
strategy favoring complex bacterial innate immunity featuring several simultaneously
active restriction modification systems.
