The genome of Chenopodium ficifolium: developing genetic resources and a diploid model system for allotetraploid quinoa.

ABSTRACT: High-quality nuclear, chloroplast, and preliminary mitochondrial genomes have been assembled and annotated for the B genome diploid (BB: 2n = 2x = 18) figleaf goosefoot (Chenopodium ficifolium). The primary objective was to advance a simplified model system for genetic characterization and improvement of allotetraploid (AABB: 2n = 4x = 36) quinoa (Chenopodium quinoa), a nutritionally valuable, halophytic orphan crop. In addition to its diploidy and favorably small genome size, the C. ficifolium model provides a shorter generational period and smaller overall plant size as compared to C. quinoa, while displaying relevant agronomic trait variations amenable to gene-trait association studies. The C. ficifolium "Portsmouth" nuclear genome was sequenced using PacBio HiFi long-read technology an
