The ZmRACK1–ZmCDPK7–ZmAPX1 module regulates plant antiviral immunity

Journal of Integrative Plant Biology, EarlyView.
In maize, ZmRACK1 acts as a scaffold protein that bridges the cyclin‐dependent kinase ZmCDPK7 and the ascorbate peroxidase ZmAPX1, promoting ZmAPX1 activity to mitigate MCMV infection. Upon viral infection, P31 obstructs formation of the ZmRACK1‐ZmCDPK7‐ZmAPX1 complex, inhibiting ZmCDPK7‐mediated ZmAPX1 activity and promoting reactive oxygen species ...

Early Symptom Characterisation and Mitigation of Maize Lethal Necrosis Disease

Journal of Phytopathology, Volume 174, Issue 3, May/June 2026.
ABSTRACT Maize (Zea mays) is a staple crop central to food security and livelihoods across sub‐Saharan Africa. In recent years, maize production in the region has been severely affected by maize lethal necrosis disease (MLND). First reported in Kenya in 2011, MLND has spread rapidly across eastern and central Africa, leading to significant yield ...
