Brevicompanines A and B: new plant growth regulators produced by the fungus, Penicillium brevicompactum
Abstract
New plant growth regulators, named brevicompanines A 1 and B 2, have been isolated from Penicillium brevicompactum, and their structures have been established by spectroscopic methods including 2D NMR. The biological activities of 1 and 2 have been examined using bioassay methods with lettuce and rice seedlings.
