The disruption of a Galpha subunit sheds new light on the pathogenicity of Stagonospora nodorum on wheat.

Molecular plant-microbe interactions : MPMI - 1 May 2004

Abstract excerpt

Gna1, a gene encoding a Galpha subunit, a key component of signal transduction pathways, has been cloned and characterized in the wheat pathogen Stagonospora nodorum. Analysis of Gna1 expression during infection revealed a slight decrease in transcript levels shortly after germination, after which levels steadily increased until sporulation. Inactivation of Gna1 had a pleiotropic effect on phenotype. The Gna1...
