Bouvet (Bouvetøya) is a geologically young and very remote island just south of the Polar Front. Here we report samples taken during the RV “Polarstern" cruise ANTXXI/2 on 3 days in November 2003 and… (More)
In Scots pine (Pinus sylvestris), ammonium assimilation is catalysed by glutamine synthetase (GS) [EC 6.3.1.2], which is encoded by two genes, PsGS1a and PsGS1b. PsGS1b is expressed in the vascular… (More)
Predation and competition are important factors structuring Antarctic benthic communities and are expected to promote the production of chemical defenses. Tunicates are subject to little predation,… (More)
Ascidians have developed multiple defensive strategies mostly related to physical, nutritional or chemical properties of the tunic. One of such is chemical defense based on secondary metabolites. We… (More)
Hexactinellids (glass sponges) are an understudied class with syncytial organization and poor procariotic associations, thought to lack defensive secondary metabolites. Poriferans, though, are… (More)
Cocconeis neothumensis, a benthic diatom living as epiphyte on Posidonia oceanica leaves, was hypothesised to synthesize secondary metabolites inducing apoptosis in the androgenic gland of the… (More)
We report the results from the first experimental study of the fate of whale and wood remains on the Antarctic seafloor. Using a baited free-vehicle lander design, we show that whale-falls in the… (More)
Examination of the digestive and hermaphroditic glands' organic extract of the sea hare Aplysia fasciata yielded 16 metabolites, including eight sesquiterpenes, three diterpenes, and five… (More)
CONTEXT
The marine diatoms Cocconeis scutellum Ehrenberg (Bacillariophyceae) are known to trigger apoptosis in the androgenic gland of the Mediterranean crustacean Hippolyte inermis Leach (Decapoda),… (More)
