Comparison of maize, sorghum, and rice genes^a.

a Where multiple transcripts are described for a gene, the one with the longest coding sequence was used. b Zm = maize; Sb = sorghum; Os = rice. “all” refers to the entire set of 544 maize genes; “syn” refers to a set of 341 presumed orthologous and syntenic genes in each species. For consistency, only exons and introns within the CDS were characterized in the “syn” set.
