Genetic transformation of Populus nigra by Agrobacterium tumefaciens

Plant Cell Reports, 1994
Two clones of Populus nigra L. were tested in vivo and in vitro for their susceptibility to three different Agrobacterium tumefaciens wild-type strains evaluating number and size of resulting calluses. Strain C58 proved to be the most virulent.Various parameters affecting Agrobacterium-mediated transformation of P.

O-Methyletransferases endoplasmiques de Populus nigra

Phytochemistry, 1979
Abstract O -Methyltransferases catalysing the methylation of caffeic acid to ferulic acid, isoferulic acid and dimethylcaffeic acid were extracted from the endoplasmic reticulum of Populus glandular tissue. The significance of methoxylated cinnamic acids in secreted flavonoid biosynthesis is discussed.

Antimicrobial flavonoids from the twigs ofPopulus nigra × Populus deltoides

Natural Product Research, 2012
A bioassay-guided fractionation of the ethyl acetate extract from the twigs of the hybrid poplar 'Neva', Populus nigra L. × Populus deltoides Marsh, led to the isolation of three flavonoids, which were identified by means of spectrometric and physicochemical analysis as 5-hydroxy-7-methoxy-flavone (1), 5,7-dihydoxy-flavone (2) and 5,7-dihydroxy ...
