Abstract excerpt

The receptor-like cytoplasmic kinase BIK1 and its close homologue PBL1 have been widely recognized as central components of plant immunity. However, most genetic studies of BIK1 and PBL1 functions were carried out with single transfer DNA (T-DNA) insertional mutant alleles. Some phenotypes observed in these mutants, for example autoimmunity, have been difficult to reconcile with the proposed role of BIK1 and PBL1...
