The barley pan-genome reveals the hidden legacy of mutation breeding

Jayakodi, Padmarasu et al. (2020) 

Full paper

This paper in Nature describes the DNA sequencing and analysis of the genomes of 20 diverse barley genotypes, a pan-genome.  Surprisingly, the number of genes and the arrangement and orientation of large parts of individual chromosomes differed in the individual genomes, which will present barriers to combining desirable characters by traditional plant breeding.
