Table 2.
Number of bamboo FL-cDNAs and number of genes found in the rice genome that encode nine key enzymes in the lignin biosynthesis pathway.
| Enzymes | Bamboo cDNAs | Rice genes | Ratio (R/B) |
|---|---|---|---|
| 4-coumarate-CoA ligase (4CL) | 2 | 26 | 13.0 |
| Caffeoyl caffeoyl-CoA O-methyltransferase (CCoAOMT) | 9 | 10 | 1.1 |
| Cinnamoyl-CoA reductase (CCR) | 7 | 18 | 2.7 |
| Caffeic acid O-methyltransferase (COMT) | 2 | 10 | 5.0 |
| Cinnamate-4-hydroxylase (C4H) | 1 | 4 | 4.0 |
| Cinnamoyl alcohol dehydrogenase (CAD) | 6 | 21 | 3.5 |
| Laccase | 5 | 23 | 4.6 |
| 5-hydroxyconiferyl aldehyde O-methyltransferase (AldOMT) | 1 | 7 | 7.0 |
| 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DAHPS) | 2 | 8 | 4.0 |
The ratio of the number of rice genes to the number of bamboo cDNAs (R/B) is calculated.
