Plants with reduced amounts of lignin typically suffer from dwarfed growth, which offsets their gain in fermentable sugar yield. Here, the authors show that genome-edited poplar lines with a null and a haploinsufficient allele of CINNAMOYL-COA REDUCTASE2 (CCR2) can be obtained that have a reduced lignin level and normal growth.
