| Chemical Defense of Leguminosae. Are Quinolizidine Alkaloids Part of the Antimicrobial Defense System of Lupins?  | | | | Abstract
| Growth o f 6 bacteria (Serratia marcescens, Bacillus megaterium , Bacillus subtilis, Streptococcus viridis, Micrococcus luteus, and M ycobacterium ph lei) was inhibited by 50% if the growth m edium contained sparteine at concentrations between 0 .5 -1 0 m M . Total growth inhibition, which was bacteriostatic in nature, was achieved at 20 m M . The growth o f 6 phytopathogenic fungi was also affected: at a sparteine concentration o f 15 m M the growth o f Alternaria porri was reduced by 40% as compared to the untreated control. R espective values were 18% inhibition for Piricularia oryzae, 33% for H elminthosporium carbonum, 15% for R hizoctonia solani, 5% for Fusarium oxysporum, and 42% for Asperquillus oryzae. Since the concentrations o f quinolizidine alkaloids range from 1 -2 0 0 m M (roots, leaves, or stems) or 1 0 -2 0 0 m m ol/k g (seeds) in Legum inosae, it is discussed whether quinolizidine alkaloids are involved in the antim icrobial defense o f lupins, in addition to their potential role as allelopathic or herbivore repellent defense com pounds. | | | |
