The seeds of Spartium junceum contained a large quantity of lectin-like protein that did not appear to be either a hemagglutinin or active lectin. The cross-reactive material (CRM), like most legume seed lectins, was a tetrameric glycoprotein of about 130,000 M(r). The singlesized subunits of about 33,000 M(r) were not covalently associated. The amino acid composition was typical of legume lect...

Although pterocarpan phytoalexins commonly ac­ cumulate in the fungus-inoculated tissues of papilionate legumes, only three compounds of this type possess oxygenation at C-2 [1, 2]. They are 2,3,9-trimethoxypterocarpan (1), 2,9-dimethoxy-3-hydroxypterocarpan (2-methoxymedicarpin, 2) and 2,3,9-trimethoxy-4-hydroxypterocarpan (3) all of which co­ occur with pisatin in the Fusarium solani f. sp. p...
