Deletion of a Disease Resistance Nucleotide-Binding
... In total we identified three classes of mutations. The mutant originally identified from analysis of 17 F1’s is termed M1, and the other two classes of mutants identified from selfed HARO4272 lines are M2 and M3, respectively. Of the four rearranged plants of the M2 class, only one was in homozygous ...
