The Arabidopsis thaliana phyB, phyD, and phyE phytochrome apoproteins show higher amino acid sequence similarity to each other than to phyA or phyC, they are the most recently evolved members of this photoreceptor family, and they may interact in regulating photomorphogenesis. The expression patterns of translational fusions of the 5' upstream regions of the PHYB, PHYD, and PHYE genes to the be...

Cells of yellow-poplar (Liriodendron tulipifera L.) were transformed by direct gene transfer and regenerated into plants by somatic embryogenesis. Plasmid DNA bearing marker genes encoding beta-glucuronidase (GUS) and neomycin phosphotransferase (NPT II) were introduced by microprojectile bombardment into single cells and small cell clusters isolated from embryogenic suspension cultures. The nu...

A genomic clone for VR-ACS6, an isozyme of auxininducible ACC synthase of mungbean, was isolated, and its promoter activity was examined in transgenic tobacco. The clone contained 1,612 bp long 5' untranscribed region and its coding sequence consisted of three exons and two introns. Genomic Southern hybridization indicated that VRACS6 is a single copy gene. The transcription initiation site was...

The 5' region of the rice actin 1 gene (Act1) has been developed as an efficient regulator of foreign gene expression in transgenic rice plants. To determine the pattern and level of rice Act1 5' region activity, transgenic rice plants containing the Act1 5' region fused to a bacterial beta-glucuronidase (Gus) coding sequence were generated. Two independent clonal lines of transgenic rice plant...

Images from ‘Dub in Liminal [4_TD$DIFF]Space’ produced in 2009–2010 towards MRes Digital Art and Technology at University of Plymouth. I embrace the ‘Dub [7_TD$DIFF]Reggae’ music genre. It strips the language from songs, sometimes returning it in a fragmented form, ornamented with delays and echoes. It provides an analogy for temporal lobe seizures; I experience dub versions of events, with lan...

In this study, an efficient Agrobacterium-mediated transformation method was developed forpomegranate (Punica granatum L.), a difficult-to-transform plant. In vitro shoot segments wereinoculated with Agrobacterium tumefaciens strain LBA4404 harboring the binary vectorpBI121 carrying the neomycin phosphotransferase (nptII) gene as a selectable marker and β-glucuronidase (gus) gene as a reporter....

The HO endonuclease promotes gene conversion between mating-type alleles in yeast by a DNA double-strand break at the site of conversion (the MAT-Y/Z site). As a first step toward understanding the molecular basis of homologous recombination in higher plants, we demonstrate that expression of HO in Arabidopsis enhances intrachromosomal recombination between inverted repeats of two defective bet...
