O-Aryl-D-glucoside (4-7) and D-xyloside (8-10) derivatives were synthesized and tested on Agrobacterium virH gene induction and plant transformation. alpha- or beta-Glycosides enhanced vir activity at concentrations above 250 muM. The highest vir activity was observed with beta-glucoside derivative 4 at 10 mM. A marked difference between phenol glucoside derivative 4 and the corresponding free phenol on the growth of transformants was observed. The regenerated transgenic tissues, after transformation on medium containing acetosyringyl beta-glucoside 4, grew at twice the rate of those on medium containing only free acetosyringone (AS). Compound 4 was less toxic for tobacco explants compared to the corresponding free phenol. However, the xyloside derivatives tested (8-10) were less effective for gene induction compared with corresponding free phenols.
