A new species, Lathys ankaraensissp. n., is described based on the material collected in the Central Anatolia. The new species belongs to the humilis-group. Habitus, as well as copulatory organs of both sexes, are described and illustrated by means of line drawings and digital and SEM photographs. A key for the four Lathys species known in Turkey is also provided.

Two species of Hydractiniidae (Hydrozoa) with metagenetic life cycle have been recorded for the temperate region southwestern Atlantic Ocean: medusa stage Podocoryna tenuis and polyp P. humilis. Both adult humilis are unknown, but it is possible that they different stages same species, a hypothesis still to be tested. Colonies growing on southern king crab Lithodes santolla collected at Patagon...

Peroxidases (EC 1.1 1.1.7; donor: hydrogen-peroxide oxidoreductase) have been implicated in numerous physiological processes of potential importance in plant-pathogen interactions, including lignification (Walter, 1992), crosslinking of cell-wall components (Bradley et al., 1992), wound healing (Sherf et al., 1993), auxin oxidation (Grambow and Langenbeck-Schwich, 1979), and systemic acquired r...

PAL (EC 4.3.1.5) catalyzes the deamination of Phe to trans-cinnamic acid in the first step of the phenylpropanoid pathway, a key process for the synthesis of phenolic compounds in plants. In legumes, phenolic compounds have many important roles including flavonoid signal molecules required for nodulation, antibiotic phytoalexins for defense against pathogens, and precursors for the structural a...
