Elicitor Activity of a Fungal Product Assessed at the Single-Cell Level by a Novel Gel-Bead Method1

摘要

Elicitor fromErysiphe pisiwas incorporated into gel beads. Individual beads were placed on single cells from barley coleoptiles. The elicitor induced unusual cytoplasmic responses and temporary resistance to infection in coleoptile cells. The technique is applicable to assessment of elicitor activity at the single-cell level.
