Table 1.

Schematic representation of the shared domain architectures in O. sativa spp. japonica and indica. The numbering and domain organization for japonica is based on Rice Annotation Project Database (RAP-DB). * domain organization of the most representative combinations in the Galanthus nivalis agglutinin (GNA) family, see Supplementary Information, Table S3. ** includes also multiple repeat domain proteins. *** DUF (domain of unknown function) 3660 in spp. japonica, DUF 3404 in spp. indica.
