- Intervention effect Reduced SUS activity produced no dramatic growth phenotype in glasshouse trees.
- Intervention effect Reduced SUS lines had notable changes in wood chemistry and ultrastructure.
- Intervention effect Dry-weight percentage composition of wood polymers did not change significantly.
- Intervention effect Wood density decreased in reduced SUS lines.
- Intervention effect Lignin, hemicellulose and cellulose content per wood volume decreased.
- Mechanism SUS was not essential for cellulose biosynthesis but influenced total carbon incorporation into wood cell walls.
