Phytoremediation is a promising alternative to conventional soil clean-up methods; however, up to date, there is still not enough information on plant species suitable for application in this field of science. Therefore, plant screening on contaminated sites can lead to the identification of further species of interest. In the present study, pedological and botanical characteristics of an indus...

Hans Ris proposed in 1961 that chloroplasts might be highly derived endosymbiotic microorganisms, originally related to blue-green algae. Evidence from 1966 and earlier is reviewed to test this proposal. Elegant experiments using the unique genetic system offered by Oenothera (the evening primroses) clearly show that plastids carry heritable characters not under nuclear control. Two or even thr...

BACKGROUND Gastrointestinal parasites are one of the main restrictions to small ruminant production. Their pathological importance is primarily related to the major production losses, in quantity or quality, induced by the direct action of worms. Control of these parasites is based exclusively on the frequent use of anthelmintic drugs. However, the resistance to anthelmintics in worm population...

Several plant extracts, including certain polyphenols, prime innate lymphocytes and enhance responses to secondary stimuli. Oenothein B, a polyphenol isolated from Epilobium angustifolium and other plant sources, enhances IFNγ production by both bovine and human NK cells and T cells, alone and in response to secondary stimulation by cytokines or tumor cells. Innate immune cell responsiveness is...

Post-planting weed control methods on abandoned farmland were studied in three fi eld trials in southern Finland using a completely randomized design with four treatments and 30 to 40 replications. Mulches of 60 × 60 cm [sheet mulch – strips of plane waste and plastic fi bre, newspaper – waste paper slurry, wood chips, pure wood fi bre slurry], herbicides [i.e. glyphosate or terbuthylazine alon...
