This study examines evolutionary rate covariation between mitochondrial and nuclear-encoded OXPHOS genes in papilionoid legumes, finding accelerated substitution rates and relaxed purifying selection in a 50-kb inversion clade.

The paper uses phylogenetic analysis to show keel flowers evolved multiple times in legumes but did not drive diversification alone, suggesting synergistic factors like nitrogen fixation and dispersal were more important.

The paper presents an improved genome assembly for the saguaro cactus using long-read PacBio data, increasing size and gene count.
