Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Wild berries are abundant in phytochemicals that consists primarily of flavonoids, carotenoids and some related polyphenolic compounds that accumulates in skin and flesh of the fruit. These compounds are key contributors for nutritional composition of fruits with anti-oxidant capacity. Anthocyanins, one of the most conspicuous classes of flavonoids together with proanthocyanidins and their derivatives are important plant pigments responsible for the red, pink, purple, and blue colors in plants. The berries from northern latitudes are found to contain more phytochemicals with antioxidant capacity than southern clones. It is mainly due to the environmental conditions of northern hemisphere and genetic adaptation that favors higher accumulation of bioactive metabolites. Phenylpropanoid pathway is the major key regulatory system for most of the bioactive compounds including anthocyanins which itself synthesized via a branch called the flavanoid pathway. Abiotic factors, such as temperature, photoperiodism, light quality & quantity has a major role in biosynthesis and regulation mechanisms. It is usually mediated by MBW complex (R2R3 MYBs, bHLH and WD 40 repeat proteins). The present study is focused on bridging the gap between environmental cues in regulation of the biosynthesis in two non-climacteric berry species, wild bilberry (Vaccinium myrtillus) and woodland strawberry (Fragaria vesca) with response to different light conditions. Our preliminary results has shown that red and blue wavelengths are positively upregulating the anthocyanin accumulation during early to late ripening stages of bilberry. Active participation in this Nordplant kickoff meeting will help me to promote my research work and get feedbacks and suggestions among my fellow plant researchers from Nordic countries and partner institutions. It can also help me to improve my knowledge on high throughput phenotyping techniques from the talks and by visiting the cutting edge facilities and infrastructures at University of Helsinki, which can also be applied in this PhD project at later stages.
