Tools for the identification of victims of domestic abuse and modern slavery in remote services: A systematic review.

Objective: To explore the technology-based tools available for supporting the identification of victims of domestic abuse and modern slavery in remote services and consider the benefits and challenges posed by the existing tools.

Methods: We searched six academic databases. Studies were considered for inclusion if they were published in English between 2000 and 2023.

Ethanol-inducible gene expression: first step towards a new green revolution?

The introduction of dwarf varieties of cereals was fundamental to the green revolution, but in the post-genomic era, the manipulation of plant morphology could be more sophisticated. A recent publication by Tahar Ait-ali et al. describes the use of the ethanol-inducible transgene expression system to re-examine plant architecture, and the genes that determine it.

nuvA, an Aspergillus nidulans gene involved in DNA repair and recombination, is a homologue of Saccharomyces cerevisiae RAD18 and Neurospora crassa uvs-2.

A 40 kb genomic clone and 2.3 kb EcoRI subclone that rescued the DNA repair and recombination defects of the Aspergillus nidulans nuvA11 mutant were isolated and the subclone sequenced. The subclone hybridized to a cosmid in a chromosome-specific library confirming the assignment of nuvA to linkage group IV and indicating its closeness to bimD.

Polarity of meiotic gene conversion is 5' to 3' within the niaD gene of Aspergillus nidulans.

We have examined polarity of meiotic gene conversion in the niiA-niaD gene cluster of Aspergillus nidulans in two-point crosses. The type and position of the mutations represented by the niaD alleles and the correlation between the relative frequency of gene conversion and the physical position of these mutations were determined. We show that polarity of meiotic gene conversion is 5' to 3' (transcribed strand) within the niaD gene.

The isolation of mutagen-sensitive nuv mutants of Aspergillus nidulans and their effects on mitotic recombination.

More than 200 mutants of Aspergillus nidulans were isolated as hypersensitive to the monofunctional alkylating agent MNNG and/or UV-irradiation (designated nuv mutants). Of these, 23 were selected for further characterization. All were markedly hypersensitive to both MNNG and the quasi-UV-mimetic mutagen 4-NQO.

Isolation and characterisation of nuv11, a mutation affecting meiotic and mitotic recombination in Aspergillus nidulans.

A mutant of Aspergillus nidulans, designated nuv11, has been isolated as hypersensitive to the monofunctional alkylating agent MNNG and the quasi-UV-mimetic mutagen 4-NQO. The mutation was recessive, resulting from mutation of a single gene which mapped to chromosome IV, and was non-allelic to the previously characterised repair-deficient mutations uvsB and uvsH which are also located on this linkage group. The nuv11 mutation results in slow growth, deficient intragenic and intergenic meiotic recombination, increased spontaneous chromosome instability, and increased intragenic and intergenic mitotic recombination in homozygous diploids.
