Functional groups of genes showing age-specific expression. (A) Expression of cyclin related genes relative to fruit age plotted as percent total expression for that transcript observed at each age [putative homologs of cyclins B1;2 (At5g06150), B1;4 (At2g26760); D1;1 (At1g70210);, D3;1 (At4g34160), D3;3 (At3g50070), D5;1 (At4g37630), and cyclin dependent kinases (CDK), CDKB1;2 (At2g38620), CDKB2;2 (At1g20930), CDKD1;3 (At1g18040), CDKE;1 (At5g63610); CKS1 (At2g27960)]. (B) GDSL-motif lipase/hydrolase family protein genes (putative homologs of At1g09390, At1g56670, At2g04570, At2g42990, At3g16370, At3g48460, At5g03610, At5g14450, At5g33370, At5g62930) and transcription factor SHINE1 (At 1 g15360; dotted line). (C,) Lipid transfer protein (LTP) family protein genes (putative homologs of At1g48750, At1g62510, At2g10940, At2g45180, At5g01870, At5g64080). (D) Phloem proteins. Solid lines indicate cucurbit specific phloem proteins as listed in Table 1. Dotted lines indicate putative homologs to Arabidopsis phloem proteins (ATPP) 2-A genes (two for ATPP2-A1, one for ATPP2-A9, and ATPP2-A13); dashed lines are putative homologs of ATPP2-B genes (ATPP-B10 and ATPP-B12). (E) Transcription factors showing preferential expression at 12 +16 dpp (putative homologs of At1g27730, At1g50640, At2g17040, At2g26150, At2g40140, 2 g46240, At3g15210, At3g15510, At3g16770, AT3g56400, At4g11660, At4g16780, At4g39250, At5g25560, At5g51190)
