Nucleotide sequence and mutational analysis of an immunity repressor gene from Bacillus subtilis temperate phage ϕ105 [PDF]
, 1985 We have identified and sequenced a bacteriophage phi 105 gene encoding an immunity repressor, the first to be characterized from a temperate phage infecting a Gram-positive host.

Molecules, 2018 In grapevine, the MYB transcription factors play an important role in the flavonoid pathway. Here, a R2R3-MYB transcription factor, VvMYBC2L2, isolated from Vitis vinifera cultivar Yatomi Rose, may be involved in anthocyanin biosynthesis as a ...

Optimizing periodicity and polymodality in noise-induced genetic oscillators [PDF]
, 2011 Many cellular functions are based on the rhythmic organization of biological processes into self-repeating cascades of events. Some of these periodic processes, such as the cell cycles of several species, exhibit conspicuous irregularities in the form of

Microbiology Spectrum, 2022 Streptococcus suis is an important pathogen in both pigs and humans. Although the diseases associated with S. suis can typically be treated with antibiotics, such use has resulted in a sustained increase in drug resistance. Bacteria can sense and respond

Crystallization and preliminary crystallographic analysis of dUTPase from the helper phage Φ11 of Staphylococcus aureus [PDF]
, 2011 Staphylococcus aureus superantigen-carrying pathogenicity islands (SaPIs) have a determinant role in spreading virulence genes among bacterial populations that constitute a major health hazard.

Finding the center reliably: robust patterns of developmental gene expression
, 2005 We investigate a mechanism for the robust identification of the center of a developing biological system. We assume the existence of two morphogen gradients, an activator emanating from the anterior, and a co-repressor from the posterior.

Nonlinearity arising from noncooperative transcription factor binding enhances negative feedback and promotes genetic oscillations [PDF]
, 2014 We study the effects of multiple binding sites in the promoter of a genetic oscillator. We evaluate the regulatory function of a promoter with multiple binding sites in the absence of cooperative binding, and consider different hypotheses for how the ...

NINJA connects the co-repressor TOPLESS to jasmonate signalling
Nature, 2010 Jasmonoyl-isoleucine (JA-Ile) is a plant hormone that regulates a broad array of plant defence and developmental processes. JA-Ile-responsive gene expression is regulated by the transcriptional activator MYC2 that interacts physically with the jasmonate ...
