CRK and infection: Our investigation revealed six proteins that were upregulated in resistant plant material during early infection stages, three of which exhibited exclusive expression in disease-resistant genotypes: A cysteine-rich receptor-like protein kinase (CRK; A0A0R0EAZ5); A leucine-rich repeat transmembrane protein kinase (LRR-RLK; A0A0R0H9A9); A cysteine-rich secretory protein (CRISP; I1MNJ7).
