Prevalence, host range, and characterization of multiple Palo verde broom emaravirus genomes and eriophyid mites from Parkinsonia spp. in Arizona.

ABSTRACT: The palo verde tree is native to the Sonoran Desert and consists of multiple species classified in the genus Parkinsonia, family, Fabaceae. Palo verde broom virus (PVBV), Fimoviridae, Emaravirus, is the suspect causal agent of witches' broom disease of blue palo verde, P. florida. Here, PVBV was detected in four palo verde species and two hybrids by reverse transcription polymerase chain reaction (RT-PCR) amplification of a 679-base pair (bp) fragment of RNA3, which encodes the nucleocapsid gene (NP). The prevalence of witches' broom symptoms among the different Parkinsonia species (n = 70), collected from naturally-occurring, nursery- or urban landscape trees was 54 %. Within-species PVBV infection spanned 50-100 % and 81 % across four species and two hybrids combined. The PVBV genome seg
