Bacteriol. 89:752-761. 1965.-Twenty strains of marine bacteria showing the properties of pigmentation and icthyotoxicity were studied for selected physiological features. A quantitative taxonomic analysis with an electronic computer was performed. E...

Phylogenetic relationships among species and subspecies of the Canary Island endemic lizard genus Gallotia are inferred based on nucleotide sequences of fragments of 12S ribosomal RNA and cytochrome b mitochondrial genes. The four morphologically established species have also been recognized at the molecular level. Relative affinities among species follow an eastern-western geographic transect....

In a host-range study carried out under greenhouse conditions, a total of 37 commercial fruit tree, grape, and citrus rootstocks were tested for their reaction to a population of the lesion nematode, Pratylenchus vulnus, in Spain. Twenty-five rootstocks had a Pf/Pi > 1.5. These included almond (Desmayo Rojo, 1143), apple (EM-9, EM-106), avocado (Hass), cherry (Santa Lucia 64, Camil, M x M 14, M...

Fresh material (aerial parts, leaves and stems) was collected when possible, collection data (place, date and collector) are outlined and an asterisk indicates a herbarium sample. Samples were identi"ed by M.El-Gibali, and voucher specimen are deposited at the Herbarium (CAIRC) of the National Research Center, or that of the Faculty of Science, Cairo University (CAI). P. atlantica Desf.: (1) No...

p. atlantica subsp. kurdica, with the local name of baneh, is a wild medicinal plant which grows in kurdistan, iran.  the identification of resistance gene analogs holds great promise for the development of resistant cultivars. a pcr approach with degenerate primers designed according to conserved nbs-lrr (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (r) gene...

Diversity in Pistacia has been evaluated at all molecular levels using the internal transcribed spacer 1 (ITS1) marker three species (Pistacia atlantica subsp. atlantica; vera and terebinthus), compared with other species. Results showed that ITS amplification sequencing, followed by phylogenetic analyses, identify confirm their classification, which revealed it can be used as a marker. Our res...

DNA rearrangements, including insertions, deletions, and inversions, control gene expression in numerous prokaryotic and eukaryotic systems, ranging from phase variation of surface antigens in pathogenic bacteria to generation of Ig diversity in human B cells. We report here that precise excision of the mobile element IS492 from one site on the Pseudoalteromonas atlantica chromosome directly co...
