Myrtaceae species resistance to rust caused byPuccinia psidii

Progress in Myrtaceae genetics and genomics: Eucalyptus as the pivotal genus

“…Although P. guajava is diploid, other members of this genus have been reported to be polyploid. Like any plant family, the Myrtaceae is host to many pathogens and diseases, but, one known as guava rust (Puccinia psidii), is particularly noteworthy because of its very wide host range within the family (Zauza et al 2010). Guava rust is endemic to parts of South America, but it has the potential to devastate susceptible plant communities where it is a new invader (Coutinho et al 1998).…”

Genetic variability in progenies of Eucalyptus dunnii Maiden for resistance to Puccinia psidii

“…A series of studies on rust have been conducted for the genus Eucalyptus (Dianese et al 1984, Freeman et al 2008, Zauza et al 2010) in view of the great commercial importance for the country. However, there are few reports in the literature about the disease in the species Eucalyptus dunnii Maiden, although CS Pinto et al…”

Resistance of Eucalyptus pellita to rust (Puccinia psidii)

“…Rust resistance varies according to species and provenance. Some species such as E. tereticornis, E. resinifera, E. paniculata and E. pellita are particularly resistant to the disease (Guimarães et al 2010a, Zauza et al 2010. In addition to the selection of resistant genotypes, the genetic basis of this resistance has been described.…”
