A mutational analysis of the cytosolic domain of the tomato Cf-9 disease-resistance protein shows that membrane-proximal residues are important for Avr9-dependent necrosis.

Abstract excerpt

The tomato Cf-9 gene encodes a membrane-anchored glycoprotein that imparts race-specific resistance against the tomato leaf mould fungus Cladosporium fulvum in response to the avirulence protein Avr9. Although the N-terminal half of the extracellular leucine-rich repeat (eLRR) domain of the Cf-9 protein determines its specificity for Avr9, the C-terminal half, including its small cytosolic domain, is postulated...
