Fig. 1From: Rheology of transgenic switchgrass reveals practical aspects of biomass processingStem color phenotype in the RNAi:Pv4CL1 transgenic positive (+, top) and negative (−, bottom) plant specimens. The presence of the RNAi:Pv4CL1 transgene correlated with brown stem color (top), while transgene absence correlated with green stem color (bottom). Plant 40(+) exhibited brown stem color as other positive plantsBack to article page
