Changes in in vivo DNA-protein interactions in pea phenylalanine ammonia-lyase and chalcone synthase gene promoter induced by fungal signal molecules.

Elicitor-induced protein bindings were detected on the several particular sequence motifs in two members of the pea PAL and CHS gene promoters by in vivo footprinting analyses. However, elicitor-induced changes rapidly reverted back to the uninduced pattern after the subsequent application of suppressor from M. pinodes.
