Diversity and composition of the bacterial communities associated with the Australian spittlebugs Bathyllus albicinctus and Philagra parva (Hemiptera: Aphrophoridae).

Spittlebugs and froghoppers (Hemiptera: Cercopoidea) are insects feeding on xylem, which potentially can cause significant economic damage worldwide by transmitting plant pathogenic bacteria such as Xylella fastidiosa. Australia and New Zealand are currently free from X. fastidiosa, but they are home to at least 45 native spittlebug species.

First report of barley yellow dwarf virus PAS () in oat in Australia.

Luteoviruses (family ) and poleroviruses (family ) are economically important pathogens of cereals such as wheat (), barley () and oat (). In Australia, the luteoviruses barley yellow dwarf virus PAV (BYDV PAV) and barley yellow dwarf virus MAV (BYDV MAV), along with the poleroviruses cereal yellow dwarf virus RPV (CYDV RPV) and maize yellow dwarf virus RMV (MYDV RMV), were distinguished from each other and reported in the 1980s (Sward and Lister 1988; Waterhouse and Helms 1985). The poleroviruses barley virus G (BVG) and cereal yellow dwarf virus RPS (CYDV RPS) were reported in Australia more recently (Nancarrow et al.

Genome sequence of a polerovirus isolated from wild oat in Australia.

We present the genome sequence of a polerovirus (family Solemoviridae) isolated from wild oat () in Australia. The genome sequence consists of 5,631 nucleotides and shares 87% nucleotide identity with its closest relative, cereal yellow dwarf virus RPV isolate 010 (GenBank accession number EF521830).

Turnip yellows virus variants differ in host range, transmissibility, and virulence.

Turnip yellows virus (TuYV; family Solemoviridae, genus Polerovirus, species Turnip yellows virus) is a genetically diverse virus that infects a broad range of plant species across the world. Due to its global economic significance, most attention has been given to the impact of TuYV on canola (syn. oilseed rape; Brassica napus).

First report of cereal yellow dwarf virus RPS infecting wheat in Australia.

Yellow dwarf viruses (YDVs) reduce grain yield in a wide range of cereal hosts worldwide. Cereal yellow dwarf virus RPV (CYDV RPV) and cereal yellow dwarf virus RPS (CYDV RPS) are members of the genus within the family (Scheets et al. 2020; Sõmera et al.
