sentence: We performed qRT-PCR to determine the transcription levels of AtMYB58 , AtMYB4 , and At4CL1 in WT Arabidopsis and CsMYB85-OE transgenic plants , and accordingly observed that AtMYB58 , AtMYB4 , and At4CL1 expression levels were upregulated in CsMYB85-OE transgenic plants ( Figure 8B ) and that the lignin content in these transgenic plants was 188 % higher than that in the WT plants ( Figure 8C ) .
