Abstract Background Yellow (stripe) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is an economic disease of wheat. Growth-promoting fungi (GPF) such as Trichoderma asperellum and Penicillium simplicissimum have been investigated for their potential to control yellow rust involvement in gene expression four PR proteins all-stage resistance. Results Wheat plants (cv. Sids-12) treated...

Yellow (stripe) rust, caused by the biotrophic fungus Puccinia striiformis f. sp. tritici (Pst), stands as most serious wheat disease worldwide, affecting approximately 88% of world production. Even though yellow rust generally develops in cool humid weather conditions, expansion new races adapted to warmer climates threatens zones where severe P. epidemics were infrequent, such Andalusian crop...
