The FRIGIDA gene is dominant in variants that undergo vernalization, while the FLC gene is dominant in other variants.
In this model organism, up-regulation of the FIDDLEHEAD gene suppresses cell interactions in the epidermis. The FRIGIDA gene is dominant in variants that undergo vernalization, while the FLC gene is dominant in other variants. The SUP, or SUPERMAN gene regulates some homeotic genes in this organism, whose genome is 125 megabase pairs long. In 2005, Lolle et al. reported the presence of HOTHEAD alleles from the grandparents, but not the parents of homozygous offspring of this organism. The ABC model of flower whorl formation was developed from this organism. For 10 points, name this model organism of the Brassicaceae, or mustard plant family.
