The title compound, C(26)H(39)NO(7), which was isolated from Delphinium anthriscifolium var. majus, has a lycoctonine carbon skeleton containing four six-membered rings (A, B, D and E) and three five-membered rings (C, F and G). Rings A, B and E adopt chair conformation, while ring D adopts a boat conformation. Rings C and F adopt envelope conformations.

Genetic and molecular analyses in two eudicot plants, Hong Ma* and Claude dePamphilis Department of Biology and Arabidopsis thaliana and Antirrhinum majus, have idenThe Life Sciences Consortium tified several genes that specify floral organ identity. Penn State University These studies led to the proposal of the ABC model University Park, Pennsylvania 16802 (Coen and Meyerowitz, 1991; Ma, 1994)...

Swarming cells of the sulfide-oxidizing bacterium Thiovulum majus form bands and show bioconvective patterns of swimming when placed in vessels containing H2S/O2 interfaces. Measurements of swimming velocities with video microscopic recordings under such conditions showed mean cell speeds as high as 615 microns s-1, unprecedented in bacteria.
