      Trivedi, Priyanka; Nguyen, Nga; Klavins, Linards; Kviesis, Jorens; Heinonen, Esa; Remes, Janne; Jokipii-Lukkari, Soile; Klavins, Maris; Karppinen, Katja; Jaakola, Laura; Häggman, Hely (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-09)
      In this study, cuticular wax load, its chemical composition, and biosynthesis, was studied during development of wild type (WT) bilberry fruit and its natural glossy type (GT) mutant. GT fruit cuticular wax load was comparable with WT fruits. In both, the proportion of triterpenoids decreased during fruit development concomitant with increasing proportions of total aliphatic compounds. In GT fruit, ...

      Aerial surfaces of plants are covered by a waxy cuticle protecting plants from excessive water loss and UV light. In the present study, composition and morphology of cuticular waxes of northern wild berry species bilberry (<i>Vaccinium myrtillus</i> L.), lingonberry (V. <i>vitis-idaea</i> L.), bog bilberry (V. <i>uliginosum</i> L.) and crowberry (<i>Empetrum nigrum</i> L.) were investigated. Scanning ...
    • Developmental and Environmental Regulation of Cuticular Wax Biosynthesis in Fleshy Fruits 

      Trivedi, Priyanka; Nguyen, Nga; Hykkerud, Anne Linn; Häggman, Hely; Martinussen, Inger; Jaakola, Laura; Karppinen, Katja (Journal article; Peer reviewed, 2019-04-19)
      The aerial parts of land plants are covered by a hydrophobic layer called cuticle that limits non-stomatal water loss and provides protection against external biotic and abiotic stresses. The cuticle is composed of polymer cutin and wax comprising a mixture of very-long-chain fatty acids and their derivatives, while also bioactive secondary metabolites such as triterpenoids are present. Fleshy ...
    • Recognition of candidate transcription factors related to bilberry fruit ripening by de novo transcriptome and qRT-PCR analyses 

      Nguyen, Nga; Suokas, Marko; Karppinen, Katja; Vuosku, Jaana; Jaakola, Laura; Häggman, Hely (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-02)
      Bilberry (<i>Vaccinium myrtillus</i> L.) fruits are an excellent natural resource for human diet because of their special flavor, taste and nutritional value as well as medical properties. Bilberries are recognized for their high anthocyanin content and many of the genes involved in the anthocyanin biosynthesis have been characterized. So far, neither genomic nor RNA-seq data have been available for ...
    • Trace element concentration and stable isotope ratio analysis in blueberries and bilberries: A tool for quality and authenticity control 

      Klavins, Linards; Maaga, Inessa; Bertins, Maris; Hykkerud, Anne Linn; Karppinen, Katja; Bobinas, Česlovas; Nguyen, Nga; Salo, Heikki M.; Salminen, Henriikka; Stankevica, Karina; Klavins, Maris (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-09)
      Vaccinium genus berries—wild bilberries (Vaccinium myrtillus L.) and cultivated highbush blueberries (Vaccinium corymbosum L.)—are consumed worldwide, and their consumption has a trend of stable increase. Thus, considering their wide use in ethnomedicine, for juice and jam production, as functional food, as well as their use in preparations of extracts which have application potential in pharmaceutical ...
