Figure 5: Sequence comparisons of OsSh1 and Sh4.
From: The genome sequence of African rice (Oryza glaberrima) and evidence for independent domestication
(a) Orthologous gene relationship of the OsSh1 region of O. sativa ssp. japonica (Os) with those of O. barthii (Ob) and O. glaberrima (Og). The 45-kb deletion (red triangle) resulted in the complete removal of the OsSh1 ortholog and three additional genes in O. glaberrima (red rectangle). Inversion is indicated with blue arrows. U and D represent upstream and downstream genes relative to OsSh1, respectively (U1, LOC_Os03g44680; U2, LOC_Os03g44690; OsSh1, LOC_Os03g44710; D1, LOC_Os03g44720; D2, LOC_Os03g44740; D3, LOC_Os03g44750; D4, LOC_Os03g44760; D5, LOC_Os03g44780). (b) Sequence comparison of Sh4 of O. sativa ssp. japonica and O. glaberrima. Two insertions (Ins) and three deletions (Del) of O. glaberrima compared to O. sativa ssp. japonica are shown as brown triangles and blue triangles, respectively. Ten SNPs are labeled a–j. The causative mutation (f) of the non-shattering phenotype in O. sativa is highlighted in red. This mutation did not exist in O. glaberrima.
