To gain a clue on the importance of MoPtc5 and MoPtc7 in M. oryzae virulence, we first decided to check the expression patterns of all the type 2C genes (MoPTC1, MoPTC2, MoPTC5, MoPTC6 and MoPTC7) in Guy11 during host infection, at different time points. The gene discussed is SGCG; the disease is infection.
