Plant Tissue Trypan Blue Staining During Phytopathogen Infection

Abstract

In this protocol plant tissue is stained with trypan blue dye allowing the researcher to visualize cell death. Specifically this method avoids the use of the carcinogen compound chloral hydrate, making this classical method of staining safer and faster than ever. The protocol is applied specifically to detect cell death on Arabidopsis leaves during the course of infection with necrotrophic fungus Botrytis cinerea.
