Title	Identification of resistance to barley leaf stripe using a Pyrenophora graminea transformant expressing beta-glucuronidase
Journal	European Journal of Plant Pathology
Year	1999
Pages	831-834
Author	Aragona M Porta-Puglia A
Abstract	Summary: A Pyrenophora graminea strain expressing the beta-glucuronidase gene (GUS) was obtained via genetic transformation, and used to follow the penetration of the pathogen inside barley germinating seeds and the colonization of host tissues. Significant differences between resistant and susceptible barley cuitivars were observed in the colonization of artificially-infected embryos by the fungus. These results suggest that the GUS transgenic strain of P. graminea will be useful for the early screening of barley cultivars for resistance to leaf stripe disease
