Kinase fusion proteins: intracellular R-proteins in plant immunity.

Resistance (R) genes in the Triticeae tribe include not only genes encoding the canonical intracellular nucleotide-binding leucine-rich-repeat proteins (NLRs) but also genes encoding kinase fusion proteins (KFPs). Exploring these unconventional KFPs may expand the scope of effector-triggered immunity (ETI) and will have significant implications for crop improvement. [ABSTRACT FROM AUTHOR]
