Abstract Myrtle rust is a plant disease caused by the invasive fungal pathogen Austropuccinia psidii (G. Winter) Beenken, which has global host list of 480 species. It was detected in Australia 2010 and rapid decline native Myrtaceae species, including rainforest trees Rhodamnia rubescens (Benth.) Miq. (scrub turpentine) Rhodomyrtus psidioides (G.Don) Benth. (native guava). Ex situ collections these species have been established, with goal preserving remaining genetic variation. Analysis reduced representation sequencing (DArTseq; n = 444 for R . 301 ) showed diversity distributed along latitudinal gradient across range each A panel samples ( 27 37 were resequenced at genome scale, revealing large historical e]ective population sizes, little variation among individuals inferred levels deleterious load. In , experimental assays 297) identified that are putatively resistant to myrtle rust. This highlights two important points: there tangible pathways recovery highly susceptible via genetically informed breeding program, critical need act quickly before more standing lost.
