Accumulation Dynamics of Transcripts and Proteins of Cold-Responsive Genes in Genotypes of Differing Cold Tolerance.

Identifying and characterizing cold responsive genes in associated with or responsible for low temperature tolerance is a vital part of strawberry cultivar development. In this study we have investigated the transcript levels of eight genes, two dehydrin genes, three putative ABA-regulated genes, two cold-inducible CBF genes and the alcohol dehydrogenase gene, extracted from leaf and crown tissues of three genotypes that vary in cold tolerance. Transcript levels of the CBF/DREB1 transcription factor exhibited stronger cold up-regulation in comparison to in all genotypes.

A Guide to the Variability of Flavonoids in Brassica oleracea.

Flavonoids represent a typical secondary metabolite class present in cruciferous vegetables. Their potential as natural antioxidants has raised considerable scientific interest. Impacts on the human body after food consumption as well as their effect as pharmaceutical supplements are therefore under investigation.

Intraspecific Variation in Carotenoids of Brassica oleracea var. sabellica.

Carotenoids are best known as a source of natural antioxidants. Physiologically, carotenoids are part of the photoprotection in plants as they act as scavengers of reactive oxygen species (ROS). An important source of carotenoids in European food is Brassica oleracea.
