Fig. 6From: Transcriptome analysis provides insights into the non-methylated lignin synthesis in Paphiopedilum armeniacum seedPhylogenetic analysis of monolignol pathway gene candidates among different plant species. The phylogenetic trees were constructed using maximum likelihood method with MEGA 7 software (Molecular Evolutionary Genetics Analysis version 7.0) with 1000 bootstrap replicates. Analysis of C4H, C3H, F5H, COMT, HCT, and CSE was processed together, because at least four taxa are needed for bootstrapping. a PAL, phenylalanine ammonia lyase; b C4H, cinnamate 4-hydroxylase; C3H, 4-coumarate 3-hydroxylase; F5H, ferulate-5-hydroxylase; COMT, caffeic acid O-methyltransferase; CSE, caffeoyl shikimate esterase; HCT, hydroxycinnamoyl-CoA:shikimate/quinate hydroxycinnamoyl transferase; c 4CL, 4-coumarate:CoA ligase; CCR, cinnamoyl-CoA reductase; CAD, cinnamyl alcohol dehydrogenase; d CCoAOMT, caffeoyl-CoA 3-O-methyltransferase; e CAD, cinnamyl alcohol dehydrogenaseBack to article page
