To elucidate the differences between the detoxification mechanisms of essential metal (Zn) and non-essential metal (Cd) in Littorina brevicula that is highly resistant to a wide range of heavy metal concentrations, Asian periwinkles were exposed to Cd (400 microg/L), Zn (3000 microg/L) and a mixture

Although mussels and oysters in the ocean are known to act as bioconcentrators for contaminants such as heavy metals, their ability to survive in heavily polluted water is relatively limited. The Asian periwinkle, Littorina brevicula, is one species that can accumulate a variety of environmental

The interactions between plant secondary metabolites (particularly monoterpenes) and insects are discussed. Such metabolites are likely to have influenced the evolution of cyt P450-linked detoxification systems in animals, through animal/plant coevolution. The biosynthesis of many classes of plant

Phenolic oxidative coupling protein (Hyp-1) isolated from Hypericum perforatum L. was characterized as a defense gene involved in H. perforatum recalcitrance to Agrobacterium tumefaciens-mediated transformation Hypericum perforatum L. is a reservoir of high-value secondary metabolites of increasing

The aim of this study was to use whole cell catalysts as tools for modification of selected resin acids in order to obtain value-added functional derivatives. The enzymatic bioconversion capacities of two plant species were tested towards dehydroabietic acid. Dehydroabietic acid (DHA) is an abundant

PRISEs (progesterone 5β-reductase and/or iridoid synthase-like 1,4-enone reductases) are involved in cardenolide and iridoid biosynthesis. We here investigated a PRISE (rAtSt5βR) from Arabidopsis thaliana, a plant producing neither cardenolides nor iridoids. The structure of rAtSt5βR was elucidated

Through evolution, marine snails have adapted several times independently to terrestrial life. A prime example for such transitions is the adaptation to terrestrial conditions in members of the gastropod clade of Littorinoidea (Caenogastropoda). Some species of this lineage like the periwinkle
