In the last few years genome sequencing projects have provided us with enormous amounts of DNA sequence, and the rate of new sequence accumulation continues to grow rapidly. Other sources of sequence data, such as EST projects, have further increased the information about what each genome contains. Computational tools have been essential for extracting important biological information from thos...

The light-enhanced production and accumulation of sugars is only one step in the process of cold acclimation in Hedera helix L. var. Thorndale (English ivy). Applications of 2,4-dinitrophenol to plants with different portions exposed to light and dark indicated that the mere presence or accunmulation of the light-generated promoters did not invoke an increase in hardiness. Kinetics of cold accl...

Common ivy (Hedera helix subsp. helix) is a well-known native and ornamental plant in Europe. Reports on contact dermatitis from ivy have regularly appeared since 1899. Recently, it has been suggested that allergic contact dermatitis from the plant may be under-diagnosed, partly due to lack of commercial patch test allergens. The objective of the article is to present the results of aimed patch...
