Pre and post stage of infection of Magnaporthe oryzae Oryza in wheat leaves with different resistance levels.

Blast fungus (Magnaporthe oryzae B.C. Couch) is an imminent threat to global food security because it causes serious yield losses in rice (Oryza sativa L.

Quantitative Trait Loci Conferring Leaf Rust Resistance in Hexaploid Wheat.

Leaf rust, caused by the fungal pathogen Puccinia triticina, is a major threat to wheat production in many wheat-growing regions of the world. The introduction of leaf rust resistance genes into elite wheat germplasm is the preferred method of disease control, being environmentally friendly and crucial to sustained wheat production. Consequently, there is considerable value in identifying and characterizing new sources of leaf rust resistance.

Changes in gene expression profiles as they relate to the adult plant leaf rust resistance in the wheat cv. Toropi.

Leaf rust, caused by the foliar pathogen is a major disease of wheat in the southern region of Brazil and invariably impacts on production, being responsible for high yield losses. The Brazilian wheat cultivar Toropi has proven, durable adult plant resistance (APR) to leaf rust, which uniquely shows a pre-haustorial resistance phenotype. In this study we aimed to understand the interaction between and the pre-haustorial APR in Toropi by quantitatively evaluating the temporal transcription profiles of selected genes known to be related to infection and defense in wheat.
