The evolutionary divergence of the galling habit of aphids (Homoptera: Fordinae) that induce different gall types on Pistacia spp. (Anacardiaceae) trees in the Mediterranean region was examined. The phylogenetic cladogram of the aphids that was based on sequences of mitochondrial genes (COI and COII) was constructed. Placing gall traits on the single parsimony cladogram suggests that gall types...

A phylogenetic hypothesis for the tribe Ithomiini (Lepidoptera: Nymphalidae: Danainae) is presented, based on sequences of the mitochondrial cytochrome oxidase subunits I and II (COI–COII) region and regions of the nuclear genes wingless and Elongation factor 1-alpha. Branch support for each clade is assessed, and a partition congruence index is used to explore conflict among gene regions. The ...

enzyme (Pu-NPase ID is a mi-or enzyme that eMciently phosphorolyzes adienosine and its deriyatiyes ratheT tha" Gther puri"e rmcleosides ]ike Escherichia coti Pu-NPase. The gene coding for Pu-NPase II (punB' gene) has beelt clloned andi sequenced from TH 6-2 strain. The deduced amine acid sequence of Pu-NPase II shared 54`M, iderwity with that of E. coii enzyme, while it had no significant homel...

In the title compound, [Co(C57H52N6O6)], the central CoII atom is coordinated by four pyrrole N atoms of the porphyrin core and one O atom of the crown ether. The complex has a distorted porphyrin core, with mean absolute core-atom displacements of 0.14 (10) (Ca), 0.20 (10) (Cb), 0.24 (4) (Cm) and 0.18 (10) Å (Cav), respectively. The axial Co-O bond length is 2.3380 (15) and the average Co-Np b...

In this work, we report the electrochemical response of a family Co(II) complexes, [CoII(L)3]2+ and [CoII(L’)2]2+ (L = 2,2’-bipyridine, 1,10-phenanthroline, 3,4,7,8-tetramethyl-1,10-phenanthroline, 5,6-dimethyl-1,10-phenanthroline, 4,7-diphenyl-1,10-phenanthroline; L’ terpyridine 4-chloro-terpyridine), in presence absence CO2 order to understand role redox potential molecular structure on catal...

The asymmetric unit of the title salt, [Co(C20H14N4S)(H2O)2](NO3)2, comprises a [Co(C20H14N4S)(H2O)2]2+ cation and two NO3- anions. In the complex, [Co(C20H14N4S)(H2O)2]2+ cation, the tetra-dentate 6,6'-sulfanediylbis(2,2'-bi-pyridine) ligand coordinates to the CoII cation in the equatorial positions, while two water mol-ecules occupy the axial positions, forming a compressed octa-hedral CoN4O2...
