Abstract Wild perennial plants can be domesticated to make agriculture more diverse and resilient, but many have large genomes that have been recalcitrant to analysis. Here, we report phased genome assemblies for Silphium integrifolium Michx. and S. perfoliatum L., two species native to North America under domestication, and demonstrate the utility of trio-binning for genome assembly using an interspecific hybrid.

Abstract Ever since Ernst Mayr (1) formalized species as “groups of actually or potentially interbreeding natural populations, which are reproductively isolated from other such groups” in 1942, zoologists have considered hybridization (creation of offspring by mating between two different species) to be rare and ultimately unproductive.

1 INTRODUCTION Altruism is the phenomenon where an organism improves another's fitness at the expense of its own fitness (Hamilton, 1964; Lehmann & Keller, 2006; Rousset, 2004; Taylor, 1992).
