Identification and in silico characterization of novel and conserved microRNAs in methyl jasmonate-stimulated Scots Pine (Pinus sylvestris L.) needles
(Peer reviewed; Journal article, 2020-03-28)MicroRNAs (miRNAs) are non-protein coding RNAs of ~20–24 nucleotides in length that play an important role in many biological and metabolic processes, including the regulation of gene expression, plant growth and developmental ... -
Natural Deep Eutectic Solvents for the Extraction of Phenyletanes and Phenylpropanoids of Rhodiola rosea L.
(Peer reviewed; Journal article, 2020-04-16)The extraction of Rhodiola rosea rhizomes using natural deep eutectic solvent (NADES) consisting of lactic acid, glucose, fructose, and water was investigated. A two-level Plackett–Burman design with five variables, followed ... -
Evaluation of the Swedish national environmental monitoring of pesticides (Översyn av det svenska miljöövervakningsprogrammet för växtskyddsmedel i jordbruksmark)
(NIBIO-rapport;7(18) 2021, Research report, 2021-02)Plantevernmidler er et viktig verktøy i dagens plantevernpraksis i jordbruket for å sikre gode avlinger. Miljørisikoen knyttet til det enkelte plantevernmiddel vurderes nøye før det godkjennes for bruk, men langvarig ... -
Identification and cross-validation of genetic loci conferring resistance to Septoria nodorum blotch using a German multi-founder winter wheat population
