Other claims from this paper (7)
- Intervention effect Transient expression of Pst_A23 suppresses plant basal defence, dependent on its nuclear speckle localization.
- Observation Pst_A23 is a Puccinia striiformis arginine-rich effector that localizes to host nuclear speckles in wheat.
- Intervention effect Pst_A23 overexpression altered the alternative splicing patterns of 588 wheat genes compared with control plants.
- Observation Pst_A23 directly binds two RNA motifs predicted from the altered splicing sites in vitro.
- Intervention effect Pst_A23 overexpression decreased the functional transcripts of TaXa21-H and TaWRKY53 in wheat.
- Intervention effect Silencing of TaXa21-H and TaWRKY53 impairs wheat resistance to Pst.
- Mechanism Plant pathogens produce splicing effectors that regulate host pre-mRNA splicing by direct engagement of the splicing sites, thereby interfering with host immunity.
