The presence of different glutamine synthetase isoenzymes in different Solanaceae plants and their relative antigenicities against antiglutamine synthetase from tomato leaf serum were studied. All the plants tested showed one glutamine synthetase isoenzyme except for Mandragora autumnalis, which showed two, after discontinuous polyacrylamide gel electrophoresis and specific in situ assay. Antig...

Hairy root cultures were obtained from diploid and induced tetraploid plants of Datura stramonium and analyzed by gas chromatography/mass spectrometry. Twenty alkaloids (19 for diploid and 9 for tetraploid hairy root cultures) were identified. A new tropane ester 3-tigloyloxy-6-propionyloxy-7-hydroxytropane was identified on the basis of mass spectral data. Hyoscyamine was the main alkaloid in ...

Abstract Datura stramonium L. (Solanaceae) possesses a rich tropane alkaloids (TAs) spectrum. The plant contains, in particular, the allelopathic compounds scopolamine and atropine, which are poorly soluble water, thus limiting their use agrochemical formulations as biocidal deterrent agents against herbivore insects. efficacy of hydrophobic TAs extracts could be increased with improvement diss...

However, it is not intended to encourage the isolation of the eye from the other senses, neither in its...

The nematode Meloidogyne enterolobii (Yang & Eisenback) is one of the main pathogens associated with guava tree (Psidium guajava L.) in northeastern Brazil. Considering frequency which weeds are found fruit production areas and their potential as phytonematode hosts, aim this study was to investigate reaction parasitism M. enterolobii. species evaluated for infection were Acanthospermum his...
