Other claims from this paper (9)
- Observation A cysteine-rich receptor-like kinase subfamily gene, TaCRK6, was identified from wheat cultivar Xiaoyan 6, which has durable high-temperature all-stage resistance to stripe rust.
- Association TaCRK6 expression responds to both Pst inoculation and relatively high temperature treatment.
- Intervention effect Silencing TaCRK6 significantly attenuated high-temperature all-stage resistance to Pst in XY6.
- Intervention effect Overexpression of TaCRK6 in susceptible wheat cultivar Fielder reduced Pst sporulation.
- Intervention effect Overexpression of TaCRK6 in susceptible wheat cultivar Fielder increased necrosis upon Pst infection.
- Observation TaCRK6 interacts with and primarily phosphorylates the cytoplasmic kinase TaRLCK185 at the threonine residue at position 248.
- Mechanism MAPK signalling cascades downstream of TaRLCK185 participate in activating high-temperature all-stage resistance in XY6.
- Mechanism TaRLCK185 transduces MAPK cascade signals by interacting with and phosphorylating the serine residue at position 132 of TaMAPKKK1.
- Mechanism TaCRK6-mediated phosphorylation of T248 alters the conformation of TaRLCK185, promoting its interaction with TaMAPKKK1 and activating the downstream TaMAPKKK1-TaMAPKK9-TaMAPK6 cascade.
