Plant alkaloids, one of the largest groups of natural products, provide many pharmacologically active compounds. Several genes in the biosynthetic pathways for scopolamine, nicotine, and berberine have been cloned, making the metabolic engineering of these alkaloids possible. Expression of two branching-point enzymes was engineered: putrescine N-methyltransferase (PMT) in transgenic plants of A...
Some of the earliest axon pathways to form in the vertebrate forebrain are established as commissural and retinal axons cross the midline of the diencephalon and telencephalon. To better understand axon guidance in the forebrain, we characterized the zebrafish belladonna (bel) mutation, which disrupts commissural and retinal axon guidance in the forebrain. Using a positional cloning strategy, w...
Isolated, nick-translated Pvu II fragments of Nicotiana tabacum chloroplast DNA produce specific intra- and intergeneric hybridization signals with chloroplast DNA digests from several representatives of the Solanaceae. These data, along with similarities in restriction enzyme patterns, permit construction of physical maps for Nicotiana line 92 (a cytoplasmic substitution line), Atropa belladon...
