Figure S1. Experimental setup and flower development in B. napus (a-d) and the CMS-line (e-h), respectively. Arrows connect the samples that were co-hybridised to microarrays. Arrows pointing in different directions indicate dye-swap experiments. Black and red arrows represent independent biological repetitions. (a) A mature B. napus flower. The inset shows a close-up of the reproductive floral organs. (b) B. napus inflorescence containing flower buds up to stage 3 (S3). The inset shows a flower bud at stage 4. (c) Stage 6 flower bud from B. napus, where whorls 3 and 4 are depicted (w3 and w4). (d) B. napus flower bud at early stage 8. (e) A mature flower from the CMS-line. The inset shows a close-up of a carpelloid stamen. An arrowhead points to an ovule-like structure. (f) Inflorescence from the CMS-line containing flower buds up to stage 4 (S4). (g) Stage 6 flower bud from the CMS-line, where whorls 1, 3 and 4 are depicted (w1, w3 and w4). (h) CMS flower bud at late stage 8 when petal primordia start to appear. In (c), (d), (g), and (h), sepals were removed for a better visibility of the inner whorl organs. In (b) and (f), the succession of flower bud initiation is indicated by numbers. Abbreviations: Se ? Sepal; Pe ? Petal; St ? Stamen; A ? Anther; C ? Carpel; Cl ? Carpelloid stamen. Figure S2. Shows the phylogeny of the A. thaliana multicopper oxidase, type 1 gene family. Included in the analysis is also the pollen specific multi-copper oxidase type 1 gene from B. napus. Locus names and trivial names (were applicable) are indicated. Full-length nucleotide sequences were obtained from the A. thaliana database. The tree presented is the one most parsimonious tree (length 21324) found in a heuristic search (CI=0.299, HI=0.701,RI= 0.492). Figure S3. Shows the phylogeny of the A. thaliana pectinesterase gene family. Locus names are indicated. Full-length nucleotide sequences were obtained from the A. thaliana database. The tree presented is a strict consensus of the two most parsimonious trees (length 32611) found in a heuristic search (CI=0.219, HI=0.781,RI= 0.454). Figure S4. Shows the phylogeny of the A. thaliana glycoside hydrolase 28 gene family. Locus names are indicated. Full-length nucleotide sequences were obtained from the A. thaliana database. The tree presented is a strict consensus of the four most parsimonious trees (length 24999) found in a heuristic search (CI=0.230, HI=0.770, RI= 0.525).
