^c: Small gene models (< 50 amino acids ) and pseudogenes were excluded from this analysis.
^d:TE-related: Transposable-element related genes and gene models. The rice proteome was searched against the MSU Oryza Repeat Database with TBLASTN and against the TE-related Pfam domains with hmmpfam. Genes and gene models with matches above cut-offs were annotated as TE-related gene models.
