Intra-/Inter-genomic alignment of switchgrass orthologous regions. (A) Blastz alignment dot plot of switchgrass BACs (48E09 = 122,250 bp; 65J23 = 102,051 bp). (B) VISTA percent identity plot of switchgrass BACs from both BAC perspectives. (C) Alignment of switchgrass BACs and other grasses to VISTA determined orthologous rice genome region. The hybridization probe, OsBRI1, is shown in red. Putatively fractionated genes are shown in orange (a = LOC_Os1g51980; b = LOC_Os1g52010; c = LOC_Os1g52030).
