Fig. 2. ClustalW alignments of amino acid (aa) sequences from the nucleotide binding site (NBS) RGAs cloned from Jagger and TA2460. These clones were compared with three NBS sequences from wheat Yr10, Cre3, and KSUD14, Xa1 from rice and Rp1-D from maize. Positional identities are highlighted in gray and computer generated gaps used for alignments are indicated by dashes.
