Expansion of the F3'5'H locus in grapevine chr6, and expected position of the chr8 orphan F3'5'Hp in syntenic loci on poplar chr6 and 16. Diagrams of gene colinearity between an 800-kb region containing arrayed F3'5'Hs on grapevine chr6 (in the middle of section a), and syntenic regions in poplar (on top, chr1:19,850,000..20,000,000 and chr9:6,000,000..6,150,000) and in papaya (bottom, sctg157:250,000..400,000), and between 200 kb surrounding F3'5'Hp on grapevine chr8 (in the middle of section b) and syntenic loci in poplar. Blue boxes indicate F3'5'Hs. Numbered boxes stand for genes encoding: (1) pentatricopeptide repeat-containing protein, (2) RNA recognition motif-containing protein, (3) histone mRNA exonuclease1, (4) dihydropyrimidinase, (5) calcium-dependent kinase, (6) rhodanese-like peptidyl-prolyl cis-trans isomerise, (7) zinc finger protein, (8) hypothetical protein, (9) DNA-binding protein, (10) alpha-glucosidase, (11) DNA gyrase subunit B, (12) UDP-glucuronosyltransferase, (13) microtubule-associated protein, (14) bZIP transcription factor; (15) hypothetical protein, (16) nudix hydrolase, (17) amino acid transporter, (18) hypothetical protein, (19) hypothetical protein, (20) phosphatidylinositol-4-phosphate 5-kinase, (21) cytokinin inducible protein, (22) glutamate synthase
