IS200: an old and still bacterial transposon
(Springer Verlag, 2004)
IS200 is a mobile element found in a variety of eubacterial genera, such as Salmonella, Escherichia, Shigella, Vibrio, Enterococcus, Clostridium, Helicobacter, and Actinobacillus. In addition, IS200-like elements are found ...

Different genetic requirements for repair of replication-born double-strand breaks by sister-chromatid recombination and break-induced replication
(Oxford University Press, 2007)
Homologous recombination (HR) is the major mechanism used to repair double-strand breaks (DSBs) that result from replication, but a study of repair of DSBs specifically induced during S-phase is lacking. Using an inverted-repeat ...

Functional analysis of saccharomyces cerevisiae ribosomal protein Rpl3p in ribosome synthesis
(Oxford University Press, 2007)
Ribosome synthesis in eukaryotes requires a multitude oftrans-acting factors. These factors act at many steps as the pre-ribosomal particles travel from the nucleolus to the cytoplasm. In contrast to the well-studied ...

Replication fork progression is impaired by transcription in hyperrecombinant yeast cells lacking a functional THO complex
(American Society for Microbiology, 2006)
THO/TREX is a conserved, eukaryotic protein complex operating at the interface between transcription and messenger ribonucleoprotein (mRNP) metabolism. THO mutations impair transcription and lead to increased transcrip ...

Regulation of conjugal transfer by Lrp and dam methylation in plasmid R100
(Sociedad Española de Microbiología, 2005-12)
Conjugal transfer of the F-like plasmid R100 occurs at higher frequencies in the absence of DNA adenine methylation. Lower levels of R100-encoded FinP RNA were found in a Dam- host, suggesting that Dam methylation regulates ...

Rad52-independent accumulation of joint circular minichromosomes during S phase in Saccharomyces cerevisiae
(2003)
We investigated the formation of X-shaped molecules consisting of joint circular minichromosomes (joint molecules) in Saccharomyces cerevisiae by two-dimensional neutral/neutral gel electrophoresis of psoralen-cross-linked ...

DNA adenine methylation regulates virulence gene expression in Salmonella enterica serovar typhimurium
(American Society for Microbiology, 2006)
Transcriptomic analyses during growth in Luria-Bertani medium were performed in strain SL1344 of Salmonella enterica serovar Typhimurium and in two isogenic derivatives lacking Dam methylase. More genes were repressed than ...

Microscopic and transcriptome analyses of early colonization of tomato roots by "Trichoderma harzianum".
(Institut d´Estudis Catalans, 2007)
The capacity of the fungus Trichoderma harzianum CECT 2413 to colonize roots and stimulate plant growth was analyzed. Tobacco seedlings (Nicotiana benthamiana) transferred to Petri dishes inoculated with T. harzianum ...

Protein interactions within the Set1 complex and their roles in the regulation of histone 3 lysine 4 methylation
(Elsevier, 2006)
Set1 is the catalytic subunit and the central component of the evolutionarily conserved Set1 complex (Set1C) that methylates histone 3 lysine 4 (H3K4). Here we have determined protein/protein interactions within the complex ...

An hpr1 point mutation that impairs transcription and mRNP biogenesis without increasing recombination
(American Society for Microbiology, 2006)
THO/TREX, a conserved eukaryotic protein complex, is a key player at the interface between transcription and mRNP metabolism. The lack of a functional THO complex impairs transcription, leads to transcriptiondependent ...
