investigating preference-performance relationships in aboveground-belowground life cycles: a laboratory and field study with the vine weevil (otiorhynchus sulcatus).the preference-performance hypothesis has principally considered insect herbivores with aboveground lifecycles, although the hypothesis could be equally relevant to insects with life stages occurring both aboveground and belowground. moreover, most studies have focussed on either laboratory or field experiments, with little attempt to relate the two. in this study, the preference-performance hypothesis was examined in an aboveground-belowground context in the laboratory using the vine weevil (ot ...201221867576
nonsense mutation inside anthocyanidin synthase gene controls pigmentation in yellow raspberry (rubus idaeus l.).yellow raspberry fruits have reduced anthocyanin contents and offer unique possibility to study the genetics of pigment biosynthesis in this important soft fruit. anthocyanidin synthase (ans) catalyzes the conversion of leucoanthocyanidin to anthocyanidin, a key committed step in biosynthesis of anthocyanins. molecular analysis of the ans gene enabled to identify an inactive ans allele in a yellow fruit raspberry ("anne"). a 5 bp insertion in the coding region was identified and designated as an ...201628066458
comparison of diagnostic techniques for the detection and differentiation of cherry leaf roll virus strains for quarantine purposes.some strains of cherry leaf roll virus (clrv) are considered as quarantine pests in new zealand. clrv was detected in seven plant host species: actinidia chinensis, hydrangea macrophylla, malus domestica, plantago major, ribes rubrum, rubus idaeus and rumex sp. collected from new zealand between 2005 and 2012. biological, serological and molecular techniques were compared for the detection and differentiation of clrv isolates. the biological analysis revealed differences in symptomatology and di ...201627129669
antioxidant properties and neuroprotective capacity of strawberry tree fruit (arbutus unedo).berries contain significant amounts of phytochemicals, including polyphenols, which are reported to reduce cancer risk, coronary heart disease and other degenerative diseases. these effects are mainly attributed to the antioxidant capacity of polyphenols found in berries. strawberry tree (arbutus unedo) berries are used in folk medicine but seldom eaten as fresh fruits. their phenolic profile and antioxidant capacity reveal a high potential, but they are not well characterized as a "health promo ...201022254017
