Sylleptic branching and shoot resprouting phenotypes of RAV1-engineered poplars during the second cultivation cycle. a Densities of sylleptic branches on the dominant shoots of wild-type (WT) and CsRAV1-overexpression and PtaRAV1&2-knockdown transgenics. Measurements were made in December 2014 at the end of the first growing season after the first coppicing. b Shoot number growing from the remaining 10-cm-long stumps of WT and events CsRAV1 OX and PtaRAV1&2 KD. Scoring was made before a second harvest 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)
