However, in sorghum the promoter of F3′H (Sb04g024710N in Nakei-MS3B or Sb04g024710 in M36001) does not contain the consensus sequence (Additional file3: Figure S2), suggesting that sorghum requires other MYB transcription factors for the color variation of leaf caused by infection with B. sorghicola. The gene discussed is MYB; the disease is infection.
