Shao, Wenjie, Clive, Derrick L. J.
A new family of routes to substituted phenols has been developed. 2-Bromo-3- methoxycyclohex-2-en-1-ones are readily deprotonated at C-6 and the resulting anions react smoothly with a variety of electrophiles; treatment with DBU in PhMe at room temperature then results in efficient aromatization...

Accumulation of Al in Root Mucilage of an Al-Resistant and an Al-Sensitive Cultivar of Wheat
Download1996
Archambault, D. J., Zhang, G., Taylor, G. J.
To estimate rates of Al accumulation within the symplasm, all apoplastic pools of Al need to be eliminated or accounted for. We have developed a revised kinetic protocol that allows us to estimate the contribution of mucilage-bound Al to total, nonexchangeable Al, and to eliminate the mucilage as...

Dyck, Jason, Silva, Norma Lucena C. L., Fliegel, Larry
We have isolated and characterized regions important for expression of the mouse NaGraphic/HGraphic exchanger gene. A 1.1-kilobase fragment upstream of the 5′-untranslated region contains specific DNA motifs characteristic of promoter and enhancer elements including a TATA box, two CAAT boxes, an...

Besides being the most popular drug in the world, caffeine is an attractive tool used in research to help us answer fascinating scientific questions, because caffeine impinges on a number of molecular pathways. In my research, I used caffeine to study DNA repair pathways and insect xenobiotic...

In differentiating cells, genes are silenced or transcribed through changes in chromatin organization. Active chromatin is known as euchromatin and repressive chromatin is known as heterochromatin. These active or repressive states are initiated and maintained by modifying residues of the core...

Current uptake of 15N –labeled ammonium and nitrate in flooded and non-flooded black spruce and tamarack seedlings.
Download2009
Macdonald, S. Ellen, Islam, M. Anisul
We investigated the effects of flooding for three weeks on physiological responses and uptake of NH4+ and NO3- by black spruce (Picea mariana (Mill.) BSP.) and tamarack (Larix laricina (Du Roi) K. Koch) seedlings fertilized with labeled (15NH4)2SO4 or K15NO3 in a growth chamber experiment....

DHR51 as a coordinator of heme biosynthesis and steroid hormone production to time metamorphosis in Drosophila melanogaster
DownloadFall 2019
Development from a juvenile to an adult animal is driven by pulses of steroid hormones released at precise developmental times. Inputs from the environment, timing cues, and nutritional factors are all coordinated to produce a steroid hormone pulse. Insects and in particular, the fruit fly...

Differential exudation of polypeptides by roots of aluminum-resistant and aluminum-sensitive cultivars of Triticum aestivum L. in response to aluminum stress
Download1994
Basu, A., Taylor, G. J., Basu, U.
Cultivars of Triticum aestivum differing in resistance to Al were grown under aseptic conditions in the presence and absence of Al and polypeptides present in root exudates were collected, concentrated, and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Upon exposure to...

Pulses of ecdysone, a steroid hormone, play an integral role during insect development however, how these ecdysone pulses are regulated has been relatively unexplored. I have shown that the presence of nitric oxide (NO) within the larval prothoracic gland (PG), the principal source of larval...
