查询词典 germplasm

Four different catechin content cultivars were selected from our tea germplasm appraisal database to assay the gene expression level of the seven genes, flavonol synthase, dihydroflavonol-4-reductase, leucoanthocyanidin reductase, anthocyanidin synthase, etc, which were involved in the flavonoids biosynthesis. The result showed that, the DFR and LAR transcripts were expressed increased with the increasing of tea catechin contents. Nevertheless, the others did not show this tendency clearly.
