Key Findings
- Researchers from the University of Bonn identified three new effector proteins (Tip6, Tip7, Tip8) from Ustilago maydis that interact with the maize TPL protein RELK2
- Tip6 and Tip7 interact with RELK2 in the nucleus, while Tip8 interacts outside the nucleus and can trigger cell death in non-host plants
- Tip6 and Tip7 enhance the virulence of U. maydis, showing they play distinct roles in the infection process
