NaMYB8 responds differentially to M. sexta OS elicitation in N. attenuata. A, Technical replicate means ± se of NaMYB8 transcript relative abundances quantified with RT-qPCR from pooled samples using five independent control, W+W-elicited, and W+OS-elicited plants. The inset shows a detail of rapid transient accumulation of transcripts between 15 and 120 min after elicitation. B, Mean ± se levels of NaMYB8 transcripts in unelicited and 1-h W+OS-elicited local leaves of two independent homozygous ir-MYB8 and wild-type (WT) plants (n = 3). Asterisks represent significantly different transcript abundances between genotypes within the same treatment group at P < 0.001. nd, Not detected.
