A simplified molecular method for distinguishing among species and ploidy levels in European water frogs (Pelophylax).

Western Palearctic water frogs in the genus Pelophylax are a set of morphologically similar anuran species that form hybridogenetic complexes. Fully reliable identification of species and especially of hybrid ploidy depends on karyological and molecular methods. In central Europe, native water frog populations consist of the Pelophylax esculentus complex, that is, P.

Mitochondrial genome organization and divergence in hybridizing central European waterfrogs of the Pelophylax esculentus complex (Anura, Ranidae).

Natural transfer of mitochondrial DNA has occurred between three western Palaearctic waterfrog taxa: Pelophylax lessonae, Pelophylax ridibundus and their hybridogenetic hybrid, Pelophylax kl. esculentus. The transfer is asymmetric with most P.

Kinetic properties of Pelophylax esculentus muscle FBPase.

D-Fructose-1,6-bisphosphate 1-phosphohydrolase FBPase; [EC 3.1.3.

Mononuclear and polymorphonuclear leukocytes show increased fructose-1,6-bisphosphatase activity in patients with type 1 diabetes mellitus.

The activity and localization of fructose-1,6-bisphosphatase (FBPase; EC 3.1.3.

F-actin, beta-tubulin, aldolase, and fructose-1,6-bisphosphatase in heteropteran ovarioles--I. Immunocytochemical investigations of whole-mounted ovarioles.

The distribution of F-actin, beta-tubulin, aldolase, and fructose-1,6-bisphosphatase (FBPase) in ovarioles of four heteropteran species (Ilyocoris cimicoides, Coreus marginatus, Lygus pratensis, and Notostira elongata) was investigated biochemically and immunocytochemically. Aldolase was found to be uniformly distributed in the cytoplasm of trophocytes and follicular cells, with the highest concentration in prefollicular cells. Its concentration in follicular cells increased during differentiation and reached a peak in ovarian follicles at the stage of late choriogenesis.
