背景：
1.The necrotrophic fungal pathogen Fusarium pseudograminearum (F. pseudograminearum) causes crown rot disease (CR) in wheat.
2.Methyl jasmonate (MJ) or jasmonic acid (JA)
3.SA analogues such as2,6-dichlor-oisonicotinic acid (INA,二氯异烟酸) and benzo(1,2,3)thiadiazole-7-car-bothionic acid S-methyl ester (BTH,苯并噻二唑), which are more potent inducers of SA inducible plant defences.
4.CR susceptible cultivar Kennedy and the partially field-resistant cultivar Sunco.
结果：
1.Reproducible induction of eight defence genes consisting of PR1.1, PR2 (β,1-3 glucanase), PR3 (chitinase), PR4 (wheatwin), PR5 (thaumatin-like protein), TaPERO (peroxidase), PR10 and TaGLP2a (germin-like).
2. MJ treatment induced the above pathogen responsive defence genes in both cultivars while BTH treatment weakly induced them in Kennedy only. Similarly, treatment with MJ before inoculation significantly delayed the development of necrotic symptoms for 2 weeks in both wheat cultivars, while BTH pre-treatments delayed symptom development in Kennedy only.
