Detection of two poleroviruses infecting garlic (Allium sativum) in Australia
Two near complete polerovirus genomes were assembled using high throughput sequencing (HTS) data from two separate samples of garlic cultivar ‘Glenlarge’ grown in Gatton, Queensland, Australia. Whole genome sequence comparisons showed that one contig shared 96.7% nucleotide identity with phasey bean mild yellows virus (MT966032.1) and the other, 99.8% nucleotide identity with turnip yellows virus (MT586581.1). Phylogenetic analyses further revealed that the isolates fell within the PBMYV group 2 and TuYV group 2 clades, respectively. This is the first report of these poleroviruses infecting garlic
Presence and distribution of banana bunchy top virus in Laos
Banana bunchy top virus is reported for the first time in Laos. Infected plants showed typical disease symptoms and the two complete genome sequences reported place the isolates in the Southeast Asian subgroup
Bermuda grass latent virus in Australia: genome sequence, sequence variation, and new hosts
Bermuda grass latent virus (BGLV; genus Panicovirus) is identified for the first time in Australia and in only the second country after the USA. A full-length genome sequence was obtained, which has 97% nucleotide sequence identity to that of the species exemplar isolate. Surveys for BGLV, utilising a newly designed universal panicovirus RT-PCR assay for diagnosis, demonstrated widespread infection by this virus in a broad variety of Bermuda grass cultivars (Cynodon dactylon and C. dactylon × C. transvaalensis) grown in both New South Wales and Queensland. The virus was also detected in Rhodes grass (Chloris gayana) and Kikuyu grass (Cenchrus clandestinus), which are both important pasture grasses in subtropical Australia, and the latter is also grown as turf. Furthermore, the Rhodes grass plant, which had strong mosaic symptoms, was also infected with sugarcane mosaic virus, warranting further investigations as to whether synergistic interactions occur between these two viruses

A review of the status of Avocado sunblotch viroid in Australia
Avocado sunblotch viroid (ASBVd) can seriously impact both the yield and quality of avocado fruit and is also a serious impediment to international trade because of quarantine conditions imposed by importing countries. The Australian avocado industry was among the first in the world to adopt control measures for ASBVd, an outcome of distinguished research done by Australian scientists during the 1970–80s. The status of ASBVd in Australia has not been recently reviewed and much information is either not published or difficult to find. In this review, this information has been collated and comment made on historical distribution and prevalence, in order to guide future surveys and to allow evaluation of the success of the control programs
Wongia gen. nov. (Papulosaceae, Sordariomycetes), a new generic name for two root-infecting fungi from Australia
The classification of two root-infecting fungi, Magnaporthe garrettii and M. griffinii, was examined by phylogenetic analysis of multiple gene sequences. This analysis demonstrated that M. garrettii and M. griffinii were sister species that formed a well-supported separate clade in Papulosaceae (Diaporthomycetidae, Sordariomycetes), which clusters outside of the Magnaporthales. Wongia gen. nov, is established to accommodate these two species which are not closely related to other species classified in Magnaporthe nor to other genera, including Nakataea, Magnaporthiopsis and Pyricularia, which all now contain other species once classified in Magnaporthe
