Fig. 4From: A multi-omics approach reveals function of Secretory Carrier-Associated Membrane Proteins in wood formation of Populus treesPhenotypic analysis of the wild type and the PttSCAMP3 RNAi lines. Wood density at the base of the stem (a), stem volume (b) and stem dry weight (c) in two-months-old greenhouse grown trees. Representative images of the stems of six-month-old wild type (d) and PttSCAMP3 RNAi line 3 (e) trees. f-g Light microscopy images of toluidine blue stained transverse sections taken from the base of the stems of two-months-old greenhouse grown wild type (f) and PttSCAMP3 RNAi line 3 (g) trees. H. Thickness of the cork in the wild type and the PttSCAMP3 RNAi lines at the base of the stems of two-months-old greenhouse grown trees. Asterisks indicate significant differences from the wild type at P < 0.01 (**) according to a Welch-corrected t-test. The volume of the stem is estimated with the formula volume = π · radius2 · height / 3. Vertical bars indicate ± SD. n = 5Back to article page
