^aSee Additional file 1 for the sequence sources.

^bSee Figure 1 for the enzyme name abbreviations. The number of sequences found from each genome is shown. '-' indicates that no similar sequence was found.

^cThe amidase gene located close to the urea carboxylase gene (less than 6,250 bp) is indicated with ⁺. See Additional file 2 for the distance between the genes.

^dBlastp similarity search against the downloaded rice genome showed no sequence similar to urease. However, similarity search against NCBI nr database found a sequence highly similar to urease from Oryza sativa.
