摘要：

Roots of white lupin seedlings were exposed to yeast extract, chitosan, Rhizobium loti suspension and CuCl2; and the isoflavonoids of their tissue extracts as well as their exudates were analysed by HPLC. Apart from specific responses characteristic of different elicitors, most treatments produced dramatic increases in the amounts of genistein and 2'-hydroxygenistein monoprenyls in root tissues, as well as major increases of all isoflavonoids in the exudates. The effect of symbiotic stress, in comparison to other stresses, is discussed in relation to the specificity of isoflavone production in white lupin. Copyright (C) 1997 Elsevier Science Ltd.
