Expression of genes for transcription factors PAP1 and MYBJS1, An1a, An1b and structural genes involved in the flavonoid/phenylpropanoid pathway.

<p>Relative transcript levels of genes were determined in leaves of GUS control and <i>PAP1</i> lines (PAP-8) not infested or infested with <i>Spodoptera litura</i> for 2 days. Transcript levels of genes were normalized by those of <i>NtEF1α</i>. Data are shown as the mean+standard errors (<i>n</i> = 4–5). Means followed by different small letters are significantly different (<i>P</i><0.05). Expression of genes in GUS and PAP-8 leaves after 4 days of damage are presented in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0108849#pone.0108849.s004" target="_blank">Figure S4</a>. ANS, anthocyanidin synthase; C3H, cinnamate 3-hydroxylase; C4H, cinnamate 4-hydroxylase; CHI, chalcone isomerase; CHS, chalcone synthase; 4CL, 4-coumarate coenzyme A ligase; DFR, dihydroflavonol 4-reductase; F3H, flavanone 3-hydroxylase; F3′H, flavonoid 3′-hydroxylase; FLS, flavonol synthase; PAL, phenylalanine ammonia-lyase.
