Bacterial transformation is a programmed process resulting in genetic transfer and diversity. It relies on the development of competence via regulatory circuits which are diverse and tailored to the particular lifestyle of each species. Despite this diversity, some species have been reported to trigger competence in response to antibiotics.

In response to DNA damage from ultraviolet (UV) radiation, bacteria deploy the SOS response in order to limit cell death. This bacterial SOS response is characterized by an increase in the recA gene that transactivates expression of multiple DNA repair genes. The current series of experiments demonstrate that a mammalian organ system (the cochlea) that

[SOS response of DNA repair and genetic cell instability under hypoxic conditions].
Radiatsionnaia biologiia, radioecologiia, 2011The SOS DNA repair pathway is induced in E. coli as a multifunctional cell response to a wide variety of signals: UV, X or gamma-irradiation, mitomycin C or nalidixic acid treatment, thymine starvation, etc. Triggering of the system can be used as a general and early sign of DNA damage. Additionally, the SOS-response is known to be an "error-prone" DNA

ABSTRACT Insertion sequences (IS) are widely involved in bacterial genomic plasticity by disrupting, adding, moving genomic sequences, or by activating or extinguishing gene expression. A specific family of IS, IS CR (for insertion sequence of Common Region), is thought to be ...

Irradiation of E. coli with UV light results in the formation of post-replication gaps and induction of the SOS response. Here, we investigate the dynamics of single strand gap formation and resolution in cells growing with a 50 min doubling time within ...

Plant nitrogen nutrition: enhancing plant resilience to abiotic stresses.
Journal of genetics and genomics = Yi chuan xue baoNitrogen (N) is not only an essential macronutrient for plant growth and development but also functions as a pivotal signaling molecule that orchestrates adaptive responses to various abiotic stresses, including acidic stress, aluminum toxicity, salinity,
