Overview of chromosomal locations of Bx-pathway loci in Triticeae species and maize. Locations of Bx-pathway loci determined so far are shown on each chromosome arm. S and L represent short and long arms, respectively. TaGT and ScGT genes are also designated as TaBx8 and ScBx8, respectively, in parentheses. Note that orthologs of ZmBx6 and ZmBx7 have not yet been identified in wheat and rye. Arm locations of TaBx1 to TaBx5 were reported by Nomura et al. (2003, 2005) and those of Taglu1c and Taglu1d in this study. For the other loci in wheat and rye, chromosomal assignments were performed by Nomura et al. (2003; ScBx1–ScBx5) and in this study (Taglu1a, Taglu1b, TaGTs, Scglu, and ScGT), and their arm locations were estimated based on the chromosomal synteny between wheat and rye (Devos et al., 1993). For the locations of ZmBx1 to ZmBx9 in maize, see Frey et al. (1997), Jonczyk et al. (2008), and von Rad et al. (2001). Locations of Zmglu1 and Zmglu2 were found by searching the maize sequence database.
