Genomic architecture of the qRgls2 region and its syntenic blocks in maize and rice. Maize chromosome 4 has two syntenic blocks: Zm Chr. 4-1 ranges from 238,744,350 to 238,761,826 bp (~17.5 kb), and Zm Chr. 4-2 ranges from 13,562,579 to 13,631,290 bp (~68.7 kb). In rice, the syntenic block Os Chr.2 is located on chromosome 2, from 1,334,563 to 1,456,346 bp (~121 kb). The syntenic blocks in maize are depicted as green zones; syntenic blocks between maize and rice are depicted as pink zones. The arrows indicate genes and their orientations; the dotted lines indicate regions without genes. Each pair of reversely syntenic genes with identical sequence is tinted with the same color. The 15 predicted genes in the qRgls2 region in chromosome 5 are GRMZM2G030013 (1), GRMZM2G477236 (2), GRMZM2G175137 (3), GRMZM2G099827 (4), GRMZM5G868966 (5), GRMZM2G157068 (6), GRMZM2G456088 (7), GRMZM2G157046 (8), GRMZM2G157026 (9), GRMZM2G156983 (10), AC189771.3_FG001 (11), GRMZM2G009065 (12), GRMZM2G039254 (13), GRMZM2G038791 (14), and GRMZM2G153178 (15). Zm: Zea mays; Os: Oryza sativa; Chr.: chromosome.
