Supplemental Data

Files in this Data Supplement:

• Supplemental Figure 1 - Boundary between leaf blade and sheath. (A) wild type. (B) pla2-1. lb: leaf blade, lg: ligule, ls: leaf sheath.
• Supplemental Figure 2 - Changes of leaf size in wild type, pla2 and pla1 plants. (A) Length of leaf blade. (B) Length of leaf sheath. (C) Width of leaf blade. Closed circle, open triangle and open squares represent wild type, pla2-1 and pla1-4, respectively.
• Supplemental Figure 3 - Cell sizes of the third leaf and -2 internode. (A) and (B)Epidermal cells of the third leaves. (C) and (D) Paranchyma cells of -2 internodes. (A) and (C) wild type. (B) and (D) pla2-1.
• Supplemental Figure 4 - Complementation of the pla2mutation. (A) Adult plants of wild type (left), pla2-1 (center), and pla2-1 rescued by introducing a genomic clone ofPLA2(right). (B) Inflorescence of pla2-1 rescued by introducing a genomic clone of PLA2.
• Supplemental Figure 5 - Amino acid sequence alignment of MEI2-like proteins, which is used to construct the phylogenetic tree.
• Supplemental Figure 6 - RT-PCR analysis of the PLA2 mRNA expression in different tissues. RNA was isolated from vegetative shoot apex (VS), inflorescence apex at stage In5 (IA), leaf blade (LB), leaf sheath (LS) and root (R).
