The sequence homology of co-migrating RAPD markers within a genus, across species, and among populations of a species was investigated. DNA was isolated from ten wild Brassica species with n=9 and the RAPD patterns were established using three random primers. Five RAPD markers which appeared to be characteristic for the n=9 species (genus level), four(More)
The specific mass shift in the electron affinity between 35Cl and 37Cl has been determined by tunable laser photodetachment spectroscopy to be −0.51(14) GHz. The isotope shift was observed as a difference in the onset of the photodetachment process for the two isotopes. In addition, the electron affinity of Cl was found to be 29 138.59(22) cm−1, giving a(More)
A tandemly repeated DNA sequence present in several species of the family Brassicaceae has been characterized. Digestion of the genomic DNA from 17 species from this family revealed the presence of tandem repeats of about 175 bp monomeric size in 6 of the 11 investigated genera. All investigated genera within the tribe Brassiceae contained the sequence.(More)
A fluorinated analogue of coniferyl alcohol has been reported to be a specific inhibitor of oxidases involved in the biosynthesis of lignin. The Z isomer of beta-fluoro-coniferyl alcohol was synthesized and used for the preparation of dehydrogenation polymers (DHPs) and was also tested on lignin producing suspension cultures of spruce (Picea abies (L.)(More)
The host-pathogen interaction between lettuce (Lactuca sativa) and downy mildew (Bremia lactucae) is mainly differential and the resistance so far utilized in the host is vertical. As in many other obligate parasites, the introduction of cultivars with new vertical resistance has exerted a strong selection pressure on the pathogen resulting in significant(More)
