Differential Proteome Analysis of Chlamydomonas reinhardtii Response to Arsenic Exposure

Autor: Harry van Keulen, Robert Wei, Belinda Willard, Chamari Walliwalagedara

Publikováno v: American Journal of Plant Sciences. :764-772

The fresh water unicellular green alga Chlamydomonas reinhardtii was used to explore whether it could function as a model system to identify proteins that are differentially expressed in response to arsenate exposure. Cells were treated with differen

Arsenate-induced expression of a class III chitinase in the dwarf sunflower Helianthus annuus

Autor: Robert Wei, Harry van Keulen, Teresa J. Cutright

Publikováno v: Environmental and Experimental Botany. 63:281-288

Dwarf sunflower cultivars of Helianthus annuus were exposed to 30 mg/L As alone and in combination with other toxic metals (30 mg/L each of Cd, Cr, and Ni). Total uptake of metals at the end of a 17-day exposure cycle showed variable sequestration of

Hydroponic phytoremediation of Cd, Cr, Ni, As, and Fe: Can Helianthus annuus hyperaccumulate multiple heavy metals?

Autor: Harry van Keulen, Teresa J. Cutright, Mary Catherine January, Robert Wei

Publikováno v: Chemosphere. 70:531-537

Sundance sunflowers were subjected to contaminated solutions containing 3, 4, or 5 heavy metals, with and without EDTA. The sunflowers exhibited a metal uptake preference of Cd=Cr>Ni, Cr>Cd>Ni>As and Fe>>As>Cd>Ni>Cr without EDTA and Cr>Cd>Ni, Fe>>As>

Development of Species-specific rDNA Probes for Giardia by Multiple Fluorescent In Situ Hybridization Combined with Immunocytochemical Identification of Cyst Wall Antigens

Autor: Edward L. Jarroll, P M Wallis, Stanley L. Erlandsen, Harry van Keulen

Publikováno v: Journal of Histochemistry & Cytochemistry. 53:917-927

In this study, we describe the development of fluorescent oligonucleotide probes to variable regions in the small subunit of 16S rRNA in three distinct Giardia species. Sense and antisense probes (17–22 mer) to variable regions 1, 3, and 8 were lab

Publikováno v: Antonie van Leeuwenhoek. 83:149-154

The composition of wine yeast populations, present during spontaneous fermentation of Chardonnay, Pinot Gris and Riesling from the Lake Erie Region was studied. A combination of biochemical and molecular techniques was used to identify non-Saccharomy

Giardia intestinalis trophozoites encyst when they are exposed to bile. During encystment, events related to the inducible synthesis of a novel N-acetyl-d-galactosamine (GalNAc) homopolymer, occur. Within the first 6 h of encystment, mRNA for glucosa

Giardia intestinalis Glucosamine 6-Phosphate Isomerase: the Key Enzyme to Encystment Appears to be Controlled by Ubiquitin Attachment

Autor: Alex B Lopez, Harry van Keulen, Mohammed T Hossain

Publikováno v: The Journal of Eukaryotic Microbiology. 49:134-136

The cyst wall of the parasitic protozoan, Giardia intestinalis, is composed of a polymer of N-acetylgalactosamine, the precursor of which is synthesized by an inducible enzyme pathway. The first enzyme in this pathway, glucosamine 6-phosphate isomera
