Molecular Cloning and Expression Analysis of hyp-1 Type PR-10 Family Genes in Hypericum perforatum
Karppinen, Katja; Derzso, Emese; Jaakola, Laura; Hohtola, Anja (Journal article; Peer reviewed, 2016)Hypericum perforatum L. is an important medicinal plant for the treatment of depression. The plant contains bioactive hypericins that accumulate in dark glands present especially in reproductive parts of the plant. In this ... -
MYBA and MYBPA transcription factors co-regulate anthocyanin biosynthesis in blue-coloured berries
Karppinen, Katja; Lafferty, Declan J.; Albert, Nick W.; Mikkola, Nelli; McGhie, Tony K.; Allan, Andrew C.; Afzal, Bilal M.; Häggman, Hely; Espley, Richard V.; Jaakola, Laura (Peer reviewed; Journal article, 2021-08-05)The regulatory network of R2R3 MYB transcription factors in anthocyanin biosynthesis is not fully understood in blue-coloured berries containing delphinidin compounds. We used blue berries of bilberry (Vaccinium myrtillus) ... -
On the developmental and environmental regulation of secondary metabolism in Vaccinium spp. berries
Karppinen, Katja; Zoratti, Laura; Nguyenquynh, Nga; Häggman, Hely; Jaakola, Laura (Journal article; Peer reviewed, 2016)Secondary metabolites have important defense and signaling roles, and they contribute to the overall quality of developing and ripening fruits. Blueberries, bilberries, cranberries, and other Vaccinium berries are fleshy ... -
Plant defense under Arctic light conditions: Can plants withstand invading pests?
Mithöfer, Axel; Riemann, Michael; Faehn, Corine Alexis; Mrazova, Anna; Jaakola, Laura (Peer reviewed; Journal article, 2022-11-24)Global warming is predicted to change the growth conditions for plants and crops in regions at high latitudes (>60° N), including the Arctic. This will be accompanied by alterations in the composition of natural plant and ... -
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; Peer reviewed, 2018-07-02)Bilberry (Vaccinium myrtillus L.) fruits are an excellent natural resource for human diet because of their special favor, taste and nutritional value as well as medical properties. Bilberries are recognized for their high ... -
Red and blue light treatments of ripening bilberry fruits reveal differences in signalling through abscisic acid-regulated anthocyanin biosynthesis
Samkumar, Amos; Jones, Dan; Karppinen, Katja; Dare, Andrew P.; Sipari, Nina; Espley, Richard V.; Martinussen, Inger; Jaakola, Laura (Peer reviewed; Journal article, 2021-08-01)The biosynthesis of anthocyanins has been shown to be influenced by light quality. However, the molecular mechanisms underlying the light-mediated regulation of fruit anthocyanin biosynthesis are not well understood. In ... -
The role of environmental stress in fruit pigmentation
Espley, Richard V.; Jaakola, Laura (Peer reviewed; Journal article, 2023-08-09)For many fruit crops, the colour of the fruit outwardly defines its eating quality. Fruit pigments provide reproductive advantage for the plant as well as providing protection against unfavourable environmental conditions ... -
Selection and validation of reliable reference genes for gene expression studies from Monilinia vaccinii-corymbosi infected wild blueberry phenotypes
Jose, Sherin; Abbey, Joel; Jaakola, Laura; Percival, David (Peer reviewed; Journal article, 2020-07-16)Monilinia blight disease caused by Monilinia vaccinii-corymbosi (Reade) Honey (M.vc) causes severe damage and economic losses in wild blueberry growing regions. Molecular mechanisms regulating defence responses of wild ... -
Spatiotemporal modulation of flavonoid metabolism in blueberries
Günther, Catrin Sonja; Dare, Andrew P.; McGhie, Tony K.; Deng, Cecilia; Lafferty, Declan J.; Plunkett, Blue J.; Grierson, Ella R.P.; Turner, Janice L.; Jaakola, Laura; Albert, Nick W.; Espley, Richard V. (Peer reviewed; Journal article, 2020-05-13)Blueberries are distinguished by their purple-blue fruit color, which develops during ripening and is derived from a characteristic composition of flavonoid-derived anthocyanin pigments. The production of anthocyanins is ... -
Sub-arctic mosses and lichens show idiosyncratic responses to combinations of winter heatwaves, freezing and nitrogen deposition
Bokhorst, Stef; Bjerke, Jarle W.; Phoenix, Gareth K.; Jaakola, Laura; Mæhre, Hanne; Tømmervik, Hans (Peer reviewed; Journal article, 2023-02-25)Arctic ecosystems are increasingly exposed to extreme climatic events throughout the year, which can affect species performance. Cryptogams (bryophytes and lichens) provide important ecosystem services in polar ecosystems ... -
Temperature has a major effect on the cuticular wax composition of bilberry (Vaccinium myrtillus L.) fruit
Trivedi, Priyanka; Klavins, Linards; Hykkerud, Anne Linn; Kviesis, Jorens; Elferts, Didzis; Martinussen, Inger; Klavins, Maris; Karppinen, Katja; Häggman, Hely; Jaakola, Laura (Peer reviewed; Journal article, 2022-09-20)Cuticle is the first layer protecting plants against external biotic and abiotic factors and is responsive to climatic factors as well as determined by genetic adaptations. In this study, the chemical composition of bilberry ...
