Cloning and Expression Patterns of Coumarate-3-hydroxylase Gene from Angelica sinensis and Its Correlation with Content of Ferulic Acid增强出版
and analyze the correlation between its bioinformatics, expression patterns and content of ferulic acid, and to explore the functions of
ASC3H
.
Method
2
Real-time polymerase chain reaction (Real-time PCR) was used to clone the full-length cDNA of
ASC3H
based on the transcriptome dataset of
A. sinensis
, and the bioinformatics analysis of the gene sequence was carried out. Real-time PCR and high performance liquid chromatography (HPLC) were used to determine relative expression of
ASC3H
and content of ferulic acid in different root tissues of
A. sinensis
(periderm, cortex and stele).
Result
2
The open reading frame (ORF) of
ASC3H
(GenBank accession number: MN2550298) was 1 530 bp, encoding 509 amino acids, with a theoretical molecular weight of 57.86 kDa and an isoelectric point of 8.36. It was a hydrophilic protein that was located in the chloroplast with multiple phosphorylation sites and a transmembrane region, and contained a conserved domain CGYDWPKGYGPIINVW_P450 (383-399 aa) in cytochrome P450. Multiple amino acid sequence alignment analysis showed that
ASC3H
had high similarity with
C3H
from other plants, especially
Ammi majus
in Umbelliferae. The Real-time PCR revealed that
ASC3H
had different expressions in periderm, cortex and stele tissues of
A. sinensis
roots. It was found from HPLC that the cortex tissues had the highest content of ferulic acid, and the stele tissues had the lowest.
Conclusion
2
ASC3H
was successfully cloned from
A. sinensis
, and its sequence characteristics were understood more clearly, suggesting that
ASC3H
might be involved in the ferulic acid biosynthesis pathway of
A. sinensis.
This paper provided a basis for further studying the functions of the gene and exploring the biosynthesis and regulation mechanism of ferulic acid in
A. sinensis,
while laying the foundation for the genetic improvement of
