Comparative Genomics of the Genomic Region Controlling Resistance to Puccinia Polysora Underw. in Zea Mays L
Polysora rust (Southern Corn Rust) is a major disease of maize in tropical and subtropical region causing yield loss in excess of 45%. The loci governing resistance (Rpp9, RppQ and RppD) have been mapped to 10.01 bins on short arm of maize chromosome 10, which also has genes for common rust resistance like Rp1 and Rp5. With the publication of maize draft genomic sequence we tried to annotate th...
متن کاملVARIABILITY IN ISOLATES OF Puccinia polysora IN BRAZIL
The main objective of this work was to evaluate the variability of the southern rust pathogen Puccinia polysora in Brazil, based on its virulence on a set of maize (Zea mays) cultivars. Sixty single pustule isolates, from different areas of occurrence of southern rust, were evaluated for their virulence to 50 maize experimental hybrids. Six cultivars showed a clear distinction between susceptib...
متن کاملWheat leaf rust caused by Puccinia triticina.
UNLABELLED Leaf rust, caused by Puccinia triticina, is the most common rust disease of wheat. The fungus is an obligate parasite capable of producing infectious urediniospores as long as infected leaf tissue remains alive. Urediniospores can be wind-disseminated and infect host plants hundreds of kilometres from their source plant, which can result in wheat leaf rust epidemics on a continental ...
متن کاملMorphology of the rust fungus Puccinia boroniae revisited.
Puccinia boroniae Henns. is a rust fungus endemic to Australia, infecting various Boronia spp. This study describes and illustrates, using light and scanning electron microscopy, the telial stage, teliospore germination and basidiospore production of specimens collected from commercial Boronia plantations in Western Australia. Unusual formation of a single basidiospore per germinating teliospor...
متن کاملThe Myrtle rust pathogen, Puccinia psidii, discovered in Africa
Puccinia psidii, the cause of a disease today commonly referred to as Myrtle rust, is considered a high priority quarantine threat globally. It has a wide host range in the Myrtaceae and it is feared that it may result in significant damage to native ecosystems where these plants occur. The fungus is also of considerable concern to plantation forestry industries that propagate Australian Eucaly...
