Abstract: | Using a polymerase chain reaction (PCR) based method six distinct candidate disease resistant gene (R) homologs from rice have been isolated. The rice sequences are organized into two phylogenetic groups with contrasting genomic
organization patterns. The first group, represented by a single sequence, Osh359-1, is more similar to non-riceR sequences than to rice ones and has a simple genomic organization. The second group, represented by Osh359-3, contains the
remaining five rice sequences. Osh359-3 consists of a multi-gene family. The members of Osh359-3 family are further found
to be clustered together in the genome. |
