A, Diameter growth and transcript level for CAld5H (for coniferaldehyde 5-hydroxylase; also known as F5H, for ferulate 5-hydroxylase) are negatively correlated (r = −0.62; P value < 0.0001) in a hybrid backcross population of Eucalyptus (Kirst et al., 2004). CAld5H was the gene with the highest correlation to diameter growth. Similar results from Populus are shown in Figure 2. B, The negative correlation (r = −0.48; P value < 0.0001) between growth and lignin is based on measurements made in 396 genotypes of Populus family 52-124 (Novaes et al., 2009).

Figure 2.
Correlations (Spearman) of biomass growth (biom) and lignin levels with transcript abundance of specific monolignol biosynthetic genes in a interspecific pseudo-backcross pedigree of Populus (family 52-124). Analysis of lignin and microarrays estimates of relative abundance are from Novaes et al. (2009) and Drost et al. (2010). Each step of the pathway is shown with the specific genes known to be highly expressed in differentiating xylem in P. trichocarpa (Shi et al., 2010). Abbreviations of the monolignol biosynthetic enzymes are as follows: PAL, Phe ammonia-lyase; C4H, cinnamate 4-hydroxylase; HCT, hydroxycinnamoyl-CoA shikimate/quinate hydroxycinnamoyl transferase; C3H, p-coumarate 3-hydroxylase; CCoAOMT, caffeoyl-CoA O-methyltransferase; CCR, cinnamoyl-CoA reductase; CAld5H, coniferaldehyde 5-hydroxylase; COMT, caffeate 3-O-methyltransferase.

Model for C partitioning during wood formation. Suc is the substrate for cellulose biosynthesis via Suc synthase (SUSY) in wood-forming cells. Glycolytic breakdown of Suc generates the precursors for hemicelluloses and starch accumulation. Phe may be transported from phloem or be synthesized in the cells. Precursors for hemicelluloses are derived from UDP-Glc (UDPG) through oxidation by UDP-Glc dehydrogenase (UDPG-DH; Tenhaken and Thulke, 1996). aa, Amino acids; DHAP, 3-deoxy-d-arabino-heptulosonate 7-phosphate; E4P, erythrose 4-P; G6P, Glc-6-P; OPP, oxidative pentose phosphate; PEP, phosphoenolpyruvate.
