| 摘要 | Background: Plantago asiatica (P. asiatica) is an important Chinese traditional medicinal plant of the family Plantaginaceae and widely used in pharmaceutical industries. TCP transcription factors play an important role in plant development, but a limited number of studies on this have been reported in P. asiatica. Methods: Since genome assembly was not available, in this study, we used the de novo transcriptome assembly method to genomewide-characterize the TCP gene family in P. asiatica. Up to 70.7 M high-quality paired-end reads were generated after sequencing and a total of 12 TCP genes were cloned by the predicted bioinformatic results, which were named PaTCP1-12. Results: Phylogenetic tree, motif analysis and subcellular localization results revealed that these PaTCPs were conserved compared to those from the model plant, Arabidopsis. Expression analysis suggested that most of the TCPs were highly expressed in both the leaf and root, while PaTCP1, PaTCP6 and PaTCP9 could also be detected in the seed. Conclusions: Since seed characteristics are one of the main agronomical traits in P. asiatica, the finding of PaTCP1, PaTCP6 and PaTCP9 expression patterns in the stem suggested an important role for further plant improvement. |
