Hierarchical clustering analysis of DEPs identified in grain amyloplast during grain development. A1, A2: DEPs of ZM366 (A1) and YM49–198 (A2) involved in carbohydrate metabolism related proteins, including starch metabolism (A1-I, A2-I), photosynthesis (A1-II, A2-II), glycolysis (A1-III, A2-III), and other carbohydrate metabolism (A1-IV, A2-IV). B1, B2: DEPs of ZM366 (B1) and YM49–198 (B2) involved in nucleic acid-related proteins, including histone (B1-I, B2-I), RNA binding (B1-II, B2-II), 40S/60S ribosomal protein (B1-III, B2-III), translation initiation/elongation factor (B1-IV, B2-IV), and other nucleic acid-related proteins (B1-V, B2-V). C1, C2: DEPs of ZM366 (C1) and YM49–198 (C2) involved in stress/defense proteins, including serpin (C1-I, C2-I), serine-type endospeptidase/alpha-amylase/trypsin inhibitor (C1-II, C2-II), chaperone/heat shock protein (C1-III, C2-III), antioxidant system (C1-IV, C2-IV), and other stress/defense related proteins (C1-V, C2-V). D1, D2: DEPs of ZM366 (D1) and YM49–198 (D2) involved in transport, including ADPG brittle (D1-I, D2-I), protein transporter (D1-II, D2-II), ADP, ATP carrier (D1-III, D2-III), and others transport proteins (D1-IV, D2-IV). E1, E2: DEPs of ZM366 (E1) and YM49–198 (E2) involved in protein synthesis/assembly/degradation. F1, F2: DEPs of ZM366 (F1) and YM49–198 (F2) involved in signal transduction. Red color, the higher abundance of protein expression; Green color, the lower abundance of protein expression
