AdpA, key regulator for morphological differentiation regulates bacterial chromosome replication [PDF]

open access: yesOpen Biology, 2012
AdpA, one of the most pleiotropic transcription regulators in bacteria, controls expression of several dozen genes during Streptomyces differentiation.

Initiation of DNA replication from non-canonical sites on an origin-depleted chromosome. [PDF]

open access: yesPLoS ONE, 2014
Eukaryotic DNA replication initiates from multiple sites on each chromosome called replication origins (origins). In the budding yeast Saccharomyces cerevisiae, origins are defined at discrete sites.

Open Questions about the Roles of DnaA, Related Proteins, and Hyperstructure Dynamics in the Cell Cycle

open access: yesLife, 2023
The DnaA protein has long been considered to play the key role in the initiation of chromosome replication in modern bacteria. Many questions about this role, however, remain unanswered.

Separation of DNA replication from the assembly of break-competent meiotic chromosomes. [PDF]

open access: yesPLoS Genetics, 2012
The meiotic cell division reduces the chromosome number from diploid to haploid to form gametes for sexual reproduction. Although much progress has been made in understanding meiotic recombination and the two meiotic divisions, the processes leading up ...

Re-replication of a centromere induces chromosomal instability and aneuploidy. [PDF]

open access: yesPLoS Genetics, 2015
The faithful inheritance of chromosomes during cell division requires their precise replication and segregation. Numerous mechanisms ensure that each of these fundamental cell cycle events is performed with a high degree of fidelity.

High Osmolarity Modulates Bacterial Cell Size through Reducing Initiation Volume in Escherichia coli

open access: yesmSphere, 2018
Bacterial cell size is closely associated with biomass growth and cell cycle progression, including chromosome replication and cell division. It is generally proposed that Escherichia coli cells tightly control the timing of chromosome replication ...

Transcription shapes DNA replication initiation to preserve genome integrity

open access: yesGenome Biology, 2021
Background Early DNA replication occurs within actively transcribed chromatin compartments in mammalian cells, raising the immediate question of how early DNA replication coordinates with transcription to avoid collisions and DNA damage.

Structure and Function of the Campylobacter jejuni Chromosome Replication Origin

open access: yesFrontiers in Microbiology, 2018
Campylobacter jejuni is the leading bacterial cause of foodborne infections worldwide. However, our understanding of its cell cycle is poor. We identified the probable C.

Escherichia coli cell factories with altered chromosomal replication scenarios exhibit accelerated growth and rapid biomass production

open access: yesMicrobial Cell Factories, 2022
Background Generally, bacteria have a circular genome with a single replication origin for each replicon, whereas archaea and eukaryotes can have multiple replication origins in a single chromosome.

Functional centromeres determine the activation time of pericentric origins of DNA replication in Saccharomyces cerevisiae. [PDF]

open access: yesPLoS Genetics, 2012
The centromeric regions of all Saccharomyces cerevisiae chromosomes are found in early replicating domains, a property conserved among centromeres in fungi and some higher eukaryotes. Surprisingly, little is known about the biological significance or the
