The aim of this study was to assess whether endosperm-specific carotenoid biosynthesis influenced core metabolic processes in maize embryo and endosperm and how global seed metabolism adapted to this expanded biosynthetic capacity. Although enhancement of carotenoid biosynthesis was targeted to the endosperm of maize kernels, a concurrent up-regulation of(More)
A commercial plant extract derived from olive tree leaf (Olea europaea) (LExt) and its major compound, oleuropein (Ole), inhibited the in vitro infectivity of the viral haemorrhagic septicaemia virus (VHSV), a salmonid rhabdovirus. Incubation of virus with LExt or Ole before infection reduced the viral infectivity to 10 and 30%, respectively. Furthermore,(More)
OBJECTIVES The aim of this study was to test the efficacy of an antioxidant/anti-inflammatory supplement containing standardized lemon verbena (Aloysia triphylla, Lippia citriodora) extract and fish oil omega-3 fatty acid in a human pilot trial as an alternative treatment for joint management. METHODS AND DESIGN First, antioxidant activity of the(More)
Tomato and its processed products are one of the most widely consumed fruits. Its domestication, however, has resulted in the loss of some 95% of the genetic and chemical diversity of wild relatives. In order to elucidate this diversity, exploit its potential for plant breeding, as well as understand its biological significance, analytical approaches have(More)
Maize was genetically engineered for the biosynthesis of the high value carotenoid astaxanthin in the kernel endosperm. Introduction of a β-carotene hydroxylase and a β-carotene ketolase into a white maize genetic background extended the carotenoid pathway to astaxanthin. Simultaneously, phytoene synthase, the controlling enzyme of carotenogenesis, was(More)
In a red bacterial strain SF238 belonging to Sporosarcina aquimarina, a C30 carotenoid biosynthetic pathway was identified. It has been reconstructed by analysis of intermediates that accumulate in two different pigment mutants. It starts with the synthesis of 4,4′-diapophytoene and proceeds with its desaturation to 4,4′-diapolycopene, which is then(More)
The complete characterization of two compounds obtained from the acetone extract of Populus tremula knotwood has been was achieved using LC-DAD-MS, MS/MS, IR and NMR. The new compounds were unequivocally identified as a mixture of the ester isomers of the (E) and (Z) p-coumarate of 1-O-rutinose. The isomers showed the capacity to inhibit lipid peroxidation(More)
The rapid advances in sequencing technologies over the last decade have enabled routine sequencing of microbial genomes. Despite notable achievements, metabolomics/metabolite profiling has not progressed with the same rapidity, which in part is due to the intrinsic complex chemical nature of the metabolome. However, well characterised metabolomes are(More)
