Genomic structure of ARG2 lines, disease symptoms and pathogen growth.

(a) ARG2 domain structure and variations in the upstream cis‐regulatory elements of the resistant and susceptible ARG2 alleles. ARG2 harbors three exons with a complete ORF in SC328C, whereas the allele in TAM428 and SC265 carry different premature stop codons. ARG2 shows structural rearrangement in the 5′ UTR between the parental lines of ARG2 mapping population.

(b) Sorghum lines that show differential responses to Cs strains Csgl1 and Cs29. TAM428 and BTx623 are susceptible to both strains of Cs. All images were taken 7 days after inoculation. (c) Growth of Cs strain on sorghum lines carrying different ARG2 alleles.
