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.

Fruit ripening including softening process is a vital developmental phase for gaining appealing fruit flavour, colour and texture. Bilberry (Vaccinium myrtillus L.) fruits are well-known for their health-promoting effects. However, bilberry fruits have a short shelf-life indicating a high activity of cell wall-degrading enzymes (CWDEs) [1] that may degrade fruit pectins leading to fruit softening. Pectate lyase (PL: EC 4.2.2.2) are recognized as pectin modifying enzymes, which are capable of cleaving glycosidic bonds through a β-elimination mechanism between galacturonosyl residues and result in loosening the cell wall during the cell separation and expansion growth phase in plants. In this study, a total of 25 PL genes from bilberry genome were identified and their expression was analyzed from transcriptome data of ripening bilberries. The genes associated in ripening fruits were further studied by qRT-PCR analysis which indicated that expressions of VmPL02, VmPL06, VmPL07, and VmPL24 peaked at ripening fruit and were also induced by ABA treatment. Further, the expression of these VmPL genes was induced by red light treatment. Verification of PL activity by recombinant PL proteins produced in yeast are ongoing. To conclude, our study indicated a role for four PL genes in bilberry fruit softening. Their induction by ABA and red light indicates them to be controlled by ABA-regulatory pathway [2], which is the key ripening controller in bilberry [1]. Thus, these genes may be responsible for the short self-life of bilberry fruit by attending in pectin degradation in fruit flesh.
