One bacterial artificial chromosome (BAC) clone 14H01
(153 kb), containing Os12g0559400 and Os12g0559600, was selected
from a BAC genomic library of ADR52, and the corresponding
region was sequenced (Supplementary Fig. S1 online). One gene
that was expected to code the NBS-LRR protein was also present
on the corresponding sequences of the BAC clone 14H01, as
revealed by the rice genome automated annotation system
(RiceGAAS). Rapid amplification of cDNA ends (RACE)-PCR was
performed, and cDNA encoding coiled coil-nucleotide binding siteleucine
rich repeat (CC-NBS-LRR) protein was cloned and sequenced,
using primers designed from the sequence data of the BAC
clone 14H01A.
