Abstract

Barley adaptation in the Australian environmentinvolves selecting and subsequently enriching pre-existing geneticvariants within the European gene pool. Breeding activities havealso introduced non-European haplotypes. Selection for suitablyadapted barley varieties in Australia has led to the fixation ofseveral genes in flowering regulatory pathways. Australianvarieties are dominated by one haplotype in each gene. Identi-fying these genes and haplotypes deepens our understanding ofhow breeding selections have shaped the genome architecture inAustralian barley during its transition from Old World to NewWorld.

Keywords:long-read genome sequencing, crop breeding,environmental adaptation, solar radiation, genomic imprint, structuralvariation.
