From: Impact of RAV1-engineering on poplar biomass production: a short-rotation coppice field trial
Aboveground biomass yields of the RAV1-engineered poplars after two cultivation cycles. a Picture of the field trial after coppicing in December 2013, showing the 10-cm-long stumps. Dry aerial biomass yields of wild-type (WT) and CsRAV1-overexpression and PtaRAV1&2-knockdown transgenics, after b the first coppicing in December 2013, and c the second coppicing in December 2015. Bars represent average values ± SE (CsRAV1 OX#60 n = 30, CsRAV1 OX#37 n = 30, WT n = 29, PtaRAV1&2 KD#22 n = 30, PtaRAV1&2 KD#1 n = 30). Letters represent significant differences between genotypes (p < 0.05)
