Fig. 2From: Defined tetra-allelic gene disruption of the 4-coumarate:coenzyme A ligase 1 (Pv4CL1) gene by CRISPR/Cas9 in switchgrass results in lignin reduction and improved sugar releaseQuantitative RT-PCR analysis for expression levels of Pv4CL1, Pv4CL2, and Pv4CL3 in switchgrass. PvUbi was used as a reference. Three tissues—leaf, node, internode—were sampled at the R1 developmental stage. Values represent mean ± SD of three biological replicatesBack to article page
