“…The pathogen reached northern Asia (Kawanishi et al 2009) and Australia (Carnegie et al 2010) relatively recently. Countries in South-East Asia have native and introduced species of Myrtaceae suitable for infection by P. psidii, and its discovery in Indonesia is perhaps not surprising.…”

“…Puccinia psidii spread through South America (Telechea et al 2003), North America (Marlatt and Kimbrough 1979), Hawaii (Uchida et al 2006), Japan (Kawanishi et al 2009), Australia (as Uredo rangelii) (Carnegie et al 2010), China (Zhuang and Wei 2011), South Africa and New Caledonia (Giblin 2013). In July 2015, symptoms of rust similar to P. psidii were observed on Eucalyptus pellita and Melaleuca leucadendra in north and south Sumatra, Indonesia.…”

Over the past decade, Puccinia psidii, which causes rust on species of Myrtaceae, has spread rapidly to new areas and is now widespread. Quarantine has done little to prevent its movement through America, the Pacific, Africa, and in this report, SouthEast Asia. Puccinia psidii is reported for the first time from Indonesia on two genera of Myrtaceae, namely Eucalyptus and Melaleuca. The identity was confirmed by morphology, a molecular barcode comparison to an epitype specimen, and with a molecular phylogenetic approach. Comparison of seven microsatellite markers revealed that the genotype of the rust in Indonesia is the same as that found in Australia. The potential impacts of P. psidii in South-East Asia to the natural environment and plantation forestry are discussed in light of this first report from the region.

“…Subsequent to its first detection in Australia (Carnegie et al 2010), P. psidii has led to the near extinction of 12 species of native Australian Myrtaceae (Carnegie et al 2016;Pegg et al 2014b). The pathogen has also had a significant impact on agriculture and commercial plantation forestry in other regions where it occurs, devastating the allspice (Pimenta dioica) industry in Jamaica (MacLachlan 1938) and resulting in considerable management costs to the eucalypt industry in Brazil (Alfenas et al 2004;Ferreira 1983;Graça et al 2011).…”

The rust pathogen, Puccinia psidii, was first detected in South Africa in 2013 on a single non-native ornamental Myrtus communis tree. This prompted surveys of the country to determine its geographic distribution and host range. Previously developed microsatellite markers where used to characterize P. psidii isolates collected from these surveys. In addition, artificial inoculation studies and field observations were used to evaluate the susceptibility of native Myrtaceae to infection by P. psidii. The pathogen was found on native Myrtaceae in isolated natural situations and it was also common on exotic Myrtaceae in nurseries and gardens. Marker analysis showed that a single genotype of the rust is present in South Africa and that this Unique Pucinnia psidii genotype in South Africa 2 is different to the so-called "pandemic" strain recorded in countries outside Brazil. It was found to have a broad distribution with collections as far as 1500 km apart. The data provide firm evidence for a single introduction of the pathogen from an as yet unkown source. Its wide distribution, particularly in relatively isolated natural areas, suggests that P. psidii has been present in South Africa for much longer than implied by its first detection in the country.

“…It is for this reason that the severe impact of the recent introduction of P. psidii to Australia has been of such great concern (Glen et al 2007;Grgurinovic et al 2006;Carnegie et al 2010).…”

Species of Mycosphaerellaceae and Teratosphaeriaceae on native Myrtaceae in Uruguay: evidence of fungal host jumps

et al. 2013

Mycosphaerella species are well-known causal agents of leaf diseases on many economically and ecologically important plant species. In Uruguay, a relatively large number of Mycosphaerellaceae and Teratosphaeriaceae are found on Eucalyptus, but nothing is known of these fungi on native Myrtaceae. The aim of this study was to identify Mycosphaerellaceae and Teratosphaeriaceae species associated with leaf diseases on native Myrtaceae in Uruguay and to consider whether host jumps by the pathogen from introduced Eucalyptus to native Myrtaceae have occurred.Several native forests throughout the country were surveyed with special attention given to those located close to Eucalyptus plantations. Five species belonging to the Mycosphaerellaceae and Teratosphaeriaceae clades were found on native Myrtaceous trees and three of these had previously been reported on Eucalyptus in Uruguay. Those occurring both on Eucalyptus and native Myrtaceae included Pallidocercospora heimii, Pseudocercospora norchiensis andTeratosphaeria aurantia. In addition, Mycosphaerella yunnanensis, a species known to occur on Eucalyptus but not previously recorded in Uruguay, was found on leaves of two native Myrtaceous hosts. Because most of these species occur on Eucalyptus in countries other than Uruguay, it appears that they were introduced in this country and have adapted to be able to infect native Myrtaceae. These apparent host jumps have the potential to result in serious disease problems and they should be carefully monitored.
