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

Antioxidant Capacity and Polyphenol Content of Brown Seawedds after Heat Processing
Gaurav Rajauria, Shilpi Gupta, Nissreen Abu-Ghannam and Amit Kumar

Seaweeds or marine macroalgae are renewable living resources which are also used as food, feed and fertilizer in many parts of the world. They are able to produce a great variety of secondary metabolites. Results showed that the heat processing not only enhanced the contents of biologically active compounds in seaweeds but also the biological activity associated with these compounds as compared to the unprocessed seaweeds.

Biomass and Quercetin Accumulation Predict Drought Sensitivity in a Novel White Clover Hybrid
Wouter L. Ballizany; Rainer W. Hofmann; Brent A. Barrett

Previous research showed that levels of the flavonol quercetin (Q) were positively associated with UV stress resistance in populations of white clover (Trifolium repens L.), and inversely linked to dry matter (DM) production (Hofmann et al, 2000). Q, and to a lesser degree its precursor kaempferol (K), have been implicated as antioxidants and energy dissipating compounds in plants exposed to stress, and could be useful markers for resistance to other stress factors.

Biomass and Quercetin Accumulation Predict Drought Sensitivity in a Novel White Clover Hybrid
Wouter L. Ballizany, Rainer W. Hofmann, Brent A. Barrett

This study shows for the first time that drought resistance in a new white clover hybrid can be linked to drought-induced increases in quercetin levels, and quercetin-to-kaempferol ratio levels. Subsequent DNA-marker analysis studies will be used to identify quantitative trait loci (QTL) for improved drought resistance in white clover to combine high Q response with high herbage yield.

Effects of host plant and temperature on Aphidius colemani (Hymenoptera: Braconidae) intrinsic rate of population increase
Rostislav Zemek, Vojtech Jarosik, Jan Havelka and Fernando P. Chihale

The aim of this paper was to investigate the aphid-mediated effects of plant (Nicotiana tabacum or Vicia faba ) on A. colemani life-history characteristics. The obtained results corroborated our hypothesis that the host plant is important factor in an aphid-parasitoid relationship. Plant toxins are probably the cause of lower rate of population increase in A. colemani developed on tobacco-reared aphids.
