Orthologous Groups among Rice, Arabidopsis, Brachypodium, Maize, Poplar, Grapevine and Sorghum

A total of 232,821 representative peptide sequences from rice* (release 7), Arabidopsis (release 10), poplar (release 2.2), grapevine (release 1_12x), sorghum (release 1.4), maize (release 5b filtered set), and Brachypodium (release 1.0) were used for identification of putative orthologous groups using OrthoMCL with default parameters (Li et al., 2003). A total of 29,968 putative orthologous groups including in-paralogs were identified. Each putative orthologous group can be retrieved by searching rice locus identifier (e.g., LOC_Os09g39670), Arabidopsis gene identifier (e.g., AT4G23430), poplar gene identifier (e.g., POPTR_0001s00200), grapevine gene identifier (e.g., GSVIVG00000034001), sorghum gene identifier (e.g. Sb03g009160), maize gene identifier (e.g. GRMZM2G163956 or AC212809.2_FG002), or Brachypodium gene identifier (e.g. Bradi1g00270).

*: Transposable-element related genes were excluded from this analysis.
