LEC1 B domain is necessary and sufficient for its activity in embryogenesis. The diagrammatic representation shows LEC1 (construct 1), the non-LEC1-type AHAP3 subunit, At4g14540 (construct 2), and chimeric proteins containing A, B, and C domains from LEC1 (L) or At4g14540 (N). Constructs encoding these chimeric proteins were transformed into lec1-1 null mutants and, after drying of the T₁ seeds, the number of viable seedlings generated from seeds tested (shown in parentheses) was determined. Transformation experiments were repeated multiple times with similar results, and the total values for all experiments are reported.
