FHY3/FAR1 transposable elements generate adaptive genetic variation in the Bassia scoparia genome.

ABSTRACT:

Background

A nearly complete genome assembly consisting of 14 scaffolds, a total length of 969.6 Mb, and an N50 scaffold length of 99.88 Mb, was generated to better understand how transposable element activity has led to adaptive evolution in Bassia scoparia (kochia), an agronomically important weed.

Results

The nine largest scaffolds correspond to the nine chromosomes of the close relative, Beta vulgaris. From this assembly, 54 387 protein-coding gene loci were annotated. We determined that genes containing Far-Red Elongated Hypocotyl 3 (FHY3) or Far-Red Impaired Response 1 (FAR1) functional domains have undergone a large, kochia-specific gene family expansion. We discovered that putative Mutator Don-Robertson (MuDR) transposable elements with detectable FHY3/FAR1 domains w
