Abstract: Based on previous results that the amino acid data of 177 candidate effectors in C. graminicola, and in combination with other effectors have been reported in five typical characteristics, and by the signal peptide prediction, trans-membrane structure prediction and the basic characteristics and cysteine content of the amino acid, 82 candidate effectors have identified with the typical characteristics of effector, while these effectors were highly sequence-specific characteristics by analysis of the SMART online
