Photosynthetic Costs and Impact on Epidemiological Parameters Associated with Resistance Genes in Maize Lines Infected with .

Northern corn leaf blight, caused by , is mainly controlled by the use of resistant cultivars. Maize lines carrying individual resistance genes B37, B37, B37, and B37 express different defense symptoms having an impact on the photosynthetic activity, the accumulation of reactive oxygen species, and epidemiological parameters. Plants were inoculated with a race 0 isolate of conferring a compatible interaction with B37 and incompatible interactions with plants carrying resistance genes.

Monocyclic Components and Photosynthetic Damage Caused by Myrtle Rust in Guava Leaves.

, the causal agent of myrtle rust, was, for many years, restricted to the Americas, but since reaching Hawaii in 2005, the pathogen has expanded its global range exponentially. In Brazil, myrtle rust is the main fungal disease in guava plants. Despite this, there are few studies on guava rust epidemiology.
