Transcriptional and metabolic changes in drought tolerant potato expressing the TPS1 gene of yeast
Zsófia Juhász, Mihály Kondrák, Ferenc Marincs, Zsófia Bánfalvi

To increase drought tolerance of potato, transgenic plants expressing the trehalose-6-phosphate synthase (TPS1) gene of yeast were isolated. The transgenic potato plants exhibited improved drought tolerance, however, grow slower than the wild-type. To understand the molecular basis of this phenomenon, transcriptomes of the leaves of wild-type and TPS1-transgenic plants were analysed using a potato microarray. In addition, protein, starch, and sugar content of the leaves were investigated.

Modelling the growth inhibition of common food spoilage and pathogenic micro-organisms in the presence of solvent extracts from Irish Crucifer vegetables
Shilpi Gupta, Amit K. Jaiswal, Nissreen Abu-Ghannam

Antimicrobial activity of Irish Brassica vegetables were evaluated against a number of food spoilage and pathogenic micro-organisms. Methanolic extracts from York Cabbage showed the best activity against Listeria monocyotgenes and Salmonella abony.

Isothermal Equilibrium and Kinetic Study on the Adsorption of Copper (II) Ions by Dried Water Hyacinth Biomass (Eichhornia crassipes)
Riel Carlo O. Ingeniero, Teresita R. Perez

This study dealt with the determination of copper (Cu2+) ion adsorption capacity of dried roots and above ground vegetative structure of Eichhornia crassipes taken from Lake Palacpacquen in San Pablo, Laguna. Both the adsorption by roots and aerial portion fitted the Langmuir and Freundlich models suggesting that the biosorption mechanism is complex.

Cows On Coke! Levamisole: A Livestock De-wormer in Cocaine
Michael Swerlowycz

A study was undertaken to determine the prevalence of levamisole where cocaine was detected in coronial specimens received at the Forensic Toxicology Laboratory. Cocaine-positive cases from January 2006 onwards were re-examined to determine the presence of levamisole. Recent specimens from the Drugs & Driving Laboratory were also examined in order to obtain comparison levamisole data from a range of living subjects

The role of a light-upregulated NF-YB member in photosynthesis and development in Triticum aestivum

NF-Y TF is a heterotrimeric complex comprised of the three subunits: NF-YA, NF-YB and NF-YC. In plants each subunit is encoded by multiple genes with different mRNA expression profiles among plant organs, and in response to developmental and environmental stimuli.

The role of a light-upregulated NF-YB member in photosynthesis and development in Triticum aestivum
Troy J. Stephenson¹², C. Lynne McIntyre¹, Christopher Collet² and Gang-Ping Xue¹

Nuclear Factor Y transcription factor is a heterotrimeric complex comprised of the three subunits: NF-YA, NF-YB and NF-YC. Each of the three subunits are encoded by multiple genes in plants, with unique mRNA expression profiles within each family including differential response to development and external stimuli. In this study we identified a light-upregulated TaNF-YB subunit member involved in the regulation of chlorophyll biosynthesis, photosynthesis-related genes, anthesis and flowering time
