Ser rescues the arrested root development in gapcp double mutants. A to C, Seeds from wild-type (WT) and gapcp double mutant (g1.1g1.1 g2.1g2.1) plants were germinated in one-fifth-strength MS medium for 8 to 10 d and then transplanted for an additional 10 d to a medium with or without 0.1 mm Ser (A). The same experiment described in A was conducted with different concentrations of Ser (B) and Gly or Cys (C). Data are means ± sd (n ≥ 30). For simplicity, g stands for gapcp.
