Other claims from this paper (13)
- Observation GmMEKK2 was identified in an SMV resistant cultivar with a conserved domain.
- Intervention effect GmMEKK2 overexpression reduced SMV accumulation and disease index.
- Intervention effect GmMEKK2 overexpression improved soybean yield traits.
- Intervention effect GmMEKK2 silencing increased SMV susceptibility, disease index and viral content.
- Intervention effect GmMEKK2 silencing increased disease index and viral content.
- Intervention effect Defense genes PR1s and RPM1s were pre activated in overexpression lines before infection.
- Observation Nontransgenic plants showed severe downregulation of basic metabolic genes at 14 days after inoculation.
- Observation Nontransgenic plants showed strong induction of genomic repair genes at 14 days after inoculation.
- Observation Overexpression lines showed minimal gene expression changes following infection.
- Mechanism GmMEKK2 bound GmMKK1 and GmMPK4A and blocked the MKK1/2-MPK4 cascade.
- Mechanism GmMEKK2 blockade indirectly enhanced salicylic acid induced defense.
- Mechanism GmMEKK2 overexpression increased basal reactive oxygen species to trigger autoimmunity.
- Mechanism GmMEKK2 overexpression maintained ROS homeostasis through the antioxidant enzyme system.
