Influence of gibberellins on flower formation in Hyoscyamus niger L.

In Vitro Flower Production in Some Species of Hyoscyamus (H. pusillus L., H. arachnoideus Pojark, and H. niger L.)

Various plant organ segments including segments from roots (root tip, and root collar), stems, leaves, and also seeds of several Hyoscyamus species (i.e. H. pusillus, H. arachnoideus, annual and biennial H. niger from two distinct geographical regions) were cultured on MS media with various growth regulator combinations, to assess the ability of flower production. Statistical assessments showed...

Antimicrobial activity of the seeds of Hyoscyamus niger L. (Henbane) on microorganisms isolated from urinary tract infections

Objective: The methanol extracts obtained from the seeds of Hyoscyamus niger L. (Solanaceae) were investigated for their antimicrobial activities against the pathogens causing complicated urine tract infections. Methods: The seeds of plant were extracted with aqueous 60% methanol. The extract was screened against urinary tract pathogens (Enterococcus faecalis, Escherichia coli, Klebsiella pneum...

cDNA encoding tropinone reductase-II from Hyoscyamus niger.

Two stereospecific NADPH-dependent reductases, TR-I and TR-11, constitute a branching point in the biosynthesis of tropane alkaloids. TR-I catalyzes the stereospecific reduction of tropinone to tropine (Koelen and Gross, 1982), whereas TR-I1 reduces tropinone to pseudotropine (Drager et al., 1988). We previously characterized TRs that had been purified from cultured roots of Hyoscyamus niger (H...
