Fig. 8: qRT-PCR validation of gene expressions in I. hawkeri and I. walleriana samples.

The expression levels of selected candidate genes were normalized to GAPDH. A, B The relative expression of two nucleotide-binding site (NBS)-containing genes. C, D The relative expression of two leucine-rich repeat receptor-like kinase (LRR-RLK) genes. DOB Divine Orange Bronze Leaf, SER Super Elfin Red, FLR Florific Lavender
