Nine putative
genes were predicted in the corresponding candidate region of
Nipponbare by using a rice annotation project database (RAP-DB;
Fig. 1b). Among them, the amino acid sequences of Os12g0559300,
Os12g0559400, and Os12g0559600 were homologous to those of
NBS-LRR type disease resistance proteins (Supplementary Table S1
online). Two putative genes (Os12g0559400 and Os12g0559600)
were predicted to encode parts of one nucleotide-binding site–
leucine-rich repeat (NBS-LRR) protein, although one putative gene
(Os12g0559300) was considered to be incomplete and was nonfunctional.
