(A) Venn diagram of preliminary experiments comparing the proteins identified in a pull of full anthers and a pull of isolated meiocytes in meiosis (mix of different stages). (B)Venn diagram representing the proteins identified in rice meiocytes at early prophase I (leptotene, zygotene, and pachytene). The proteins identified at later stages (diplotene and diakinesis) were subtracted. Only peptides with 5–30 amino acids and a minimum of two peptides per protein were used for positive identification, and peptide FDR < 0.01. (C) Diagram of the biological functions associated to the 422 proteins identified only at early prophase I stages. The numbers of proteins associated to each function are in brackets.
