Fo. Bryant et al., EFFECT OF FUNGAL NATURAL-PRODUCTS IN AN AGROBACTERIUM-TUMEFACIENS POTATO DISC ASSAY, Journal of natural products, 57(5), 1994, pp. 640-643
An Agrobacterium tumefaciens potato disc assay was used to screen cert
ain natural products (25 mu g/disc) from fungi for crown gall tumor/an
titumor induction. Monorden (-75.0%), cladosporin (-79.0%), monocillin
IV (-79.6%), duclauxin (-96.0%), diplodiol (-96.3%), and chaetoglobos
in K (-99.0%) displayed concentration-dependent responses at 5, 10, 25
, and 50 mu g/disc. These natural products were not antimicrobial as d
etermined by sensitivity tests using fungi and bacteria, inclusive of
A. tumefaciens.
