Genome structure and molecular phylogeny of the only Eurasian Boechera species, Boechera falcata (Brassicaceae).

ABSTRACT: Boechera falcata (Turcz.) Al-Shehbaz, previously known as Arabis turczaninowii Ledeb., is a herbaceous perennial of the East Siberian, boreal-steppe ecotype. It is the sole species of the diverse genus Boechera found on the Eurasian continent, with all other species endemic to North America and Greenland. Likely migrating from North America to Eastern Siberia via the Bering Land Bridge during the Pleistocene glaciation, B. falcata presents a unique case for genomic study. The genus Boechera is notable for its many allodiploid and triploid apomicts, which have arisen through complex hybridization of sexual species and ecotypes. To date, only the genomes of 2 American Boechera species, B. stricta and B. retrofracta, have been sequenced and analyzed. In this study, we sequenced, assembled to
