Culturing Puccinia coronata on a Cell Monolayer of the Avena sativa Coleoptile

Abstract

A culture of Puccinia coronata on an epidermal cell monolayer dissected from the Avena sativa caleoptile is described. To induce fungal development, infection structure formation had to be induced with a heat treatment. The host cells were fed with 1 % sucrose (or glucose or manitol) to sustain fungal growth. Under these conditions, normal development of hyphae, haustoria with haustorial mother cells and uredospores occurred. Uredospores had normal infectivity. Copyright © 1983, Wiley Blackwell.
