AhASRK1, a peanut dual-specificity kinase that activates the Ca-ROS-MAPK signalling cascade to mediate programmed cell death induced by aluminium toxicity via ABA.

Aluminium (Al)-induced programmed cell death (PCD) is thought to be a main cause of Al phytotoxicity. However, the underlying mechanism by which Al induces PCD in plants is unclear. In this study, we characterized the function of AhASRK1 (Aluminum Sensitive Receptor-like protein Kinase1), an Al-induced LRR-type receptor-like kinase gene.
