(A) Segregating populations from crosses of dgat1 with lpcat2. All lines are homozygous for the dgat1 mutation and homozygous, heterozygous or null for lpcat2. The dgat1/lpcat2 H/H seedlings are circled, showing slow development. (B) Once transferred to soil, bolting is delayed in the dgat1/lpcat2 H/H seedlings. In contrast (C) dgat1/lpcat2 H/He seedlings develop and bolt normally.
