Sensitivity to Photoperiod Is a Complex Trait in <i>Camelina sativa</i>.

ABSTRACT: Day neutrality, or insensitivity to photoperiod (day length), is an important domestication trait in many crop species. Although the oilseed crop C. sativa has been cultivated since the Neolithic era, day-neutral accessions have yet to be described. We sought to leverage genetic diversity in existing germplasms to identify C. sativa accessions with low photoperiod sensitivity for future engineering of this trait. To do so, we quantified variation in hypocotyl length across 161 C. sativa accessions of 4-day-old seedlings grown in long-day and short-day conditions as a high-throughput approximation of variation in the photoperiod response. Soil-grown adult plants from selected accessions also showed variation in the response to day length in several traits; however, the
