Genetic variation in Myzus persicae populations associated with host-plant and life cycle category
(2001)Random amplified polymorphic DNA (RAPD) analysis was applied on 96 clones of Myzus persicae (Sulzer) (Homoptera: Aphididae) representing seven populations collected from different host-plants and regions of Greece. Ten ... -
Host-correlated morphological variation of Myzus persicae (Hemiptera : Aphididae) populations in Greece
(2000)Morphological variation in nine characters of 157 clones of Myzus persicae (Sulzer) was examined by multivariate analysis. The clones were collected from peach, Prunus persica, the primary host and the secondary hosts ... -
Host-related morphological variation within Myzus persicae group (Homoptera : Aphididae) from Japan
(2007)There have been independent long-term studies of tobacco-adapted populations of Myzus persicae in Japan and Greece, but until now no direct comparisons have been made between them. In Japan, as in Greece, tobacco aphids ... -
Life cycle variation of Myzus persicae (Hemiptera : Aphididae) in Greece
(2002)During the years 1995-1999 the life cycle category of 2797 clones of Myzus persicae (Sulzer) was examined. The clones originated from primary and secondary hosts from different localities of North and Central Greece and ... -
A modified method for the detection of differentially expressed mRNAs without using radioactivity
(2001)We present here a modification of the original differential display approach using a single oligo(dT) primer for the reverse transcription reaction (instead of the various oligo(dT)NM primers that subdivide the pool of ... -
The role of proton magnetic resonance spectroscopy in the diagnosis and categorization of cerebral abscesses
(2008)Despite recent advances in neuroimaging, differentiation between cerebral abscesses and necrotic tumors with ring-type contrast enhancement can be puzzling at times. The introduction of advanced imaging techniques, such ... -
A single tRNA base pair mediates bacterial tRNA-dependent biosynthesis of asparagine
(2006)In many prokaryotes and in organelles asparagine and glutamine are formed by a tRNA-dependent amidotransferase (AdT) that catalyzes amidation of aspartate and glutamate, respectively, mischarged on tRNA(Asn) and tRNA(Gln). ... -
Statistical tree classification of aphids based on morphological characteristics
(1999)Individual aphids were classified to their clones and separated to their host groups using a novel non-parametric classification tree method. The classification of the individuals was based on morphometric variables measured ...
