FIGURE 7.
Functional characterization of CsLRK10L genes. (A) Multiple protein sequence alignment of predicted proteins encoded by CsLRK10L1 and CsLRK10L2. A graph indicates conservation per amino acid. Pfam domains as identified by InterProScan v5.27 are indicated by arrows. (B) Alleles of CsLRK10L1 and CsLRK10L2 cloned from cucumber genotypes HS279 and NIL DM4.1.1/.2 were transiently expressed in Nicotiana benthamiana leaves by agro-infiltration (infiltrated leaf areas are indicated). Empty A. tumefaciens cultures were used as a negative control. CsLRK10L2 cloned from NIL DM4.1.1/.2 consistently triggered a necrotic reaction in >20 individual plants. In order to visualize necrotic tissue, leaves were stained using trypan blue.
