Genomic structures of GsAG1 and GsAG2.
a Genomic structure of GsAG1 in Japanese gentian. Open boxes show untranslated regions, filled boxes show translated regions with exons. Numerals above boxes indicate exon number. Scale bar indicates 1 kb. Open arrow indicates insertion position of transposable element Tgs1 in gsag1 in double-flowered mutant. TSD, target site duplication; LTR, long terminal repeat. Tgs1 is 5,150-bp long with an ORF encoding 1,431 amino acid sequences of a gag-pol polyprotein, 334 bp of LTRs, and 5 bp of TSDs. b Genomic structure of GsAG2 in Japanese gentian cv. Alta
