摘要
Cinnamoyl_CoA reductase (CCR) is responsible for the first committed reaction in monolignol biosynthesis, which diverts phenylpropanoid_derived metabolites into the biosynthesis of lignin. To gain a better understanding of the lignin biosynthesis in wheat development, two cDNAs encoding CCR were identified from wheat ( Triticum aestivum L. cv. H4564). DNA sequence analyses indicated that the two cDNAs represent two classes of CCR. RT_PCR and Northern blot hybridization demonstrated that one of them, W_cr6, was expressed actively in stem and leaf tissue, the other one, W_cr19, was expressed in root and stem tissue. The results suggested that there are at least two genes encoded for CCR existing in wheat genome.
