Identification and Expression Pattern of Salvia miltiorrhiza Terpenoid Synthase Gene Family
Bioinformatics methods were used to systematically identify the
Salvia miltiorrhiza
terpenoid synthase (
SmTPS
)
gene family members and predict their functions from the perspective of the genome.
Method
2
The genome and transcriptome data of
S. miltiorrhiza
,
Arabidopsis thaliana
, and tomato were obtained from the national genomics data center (NGDC), national center for biotechnology information (NCBI), the
Arabidopsis
information resource (TAIR), and tomato functional genomics database (TFGD), and the whole genome identification and bioinformatics analysis of the
SmTPS
gene family member were carried out with the help of Perl language programming, Tbtools, and other bioinformatics tools.
Result
2
A total of 52
TPS
gene family members were identified, and they were distributed on eight chromosomes of
S. miltiorrhiza
. Their coding amino acid number was 207-822 aa. The isoelectric points were 4.76-9.16. The molecular mass was 24.11-94.81 kDa, and all members are hydrophilic proteins. Gene structure analysis showed that there were significant differences in the number of introns among different subfamilies. The number of introns in 72.6% of TPS-a, b, and g subfamilies was 6, and that in 88.9% of TPS-c and e/f subfamilies was more than 10. Protein motifs were conserved among TPS subfamilies. The analysis of promoter
cis
-acting elements showed that all promoters of the
SmTPSs
contained a large number of light-responsive elements, and most of them had hormone-responsive elements. Gene expression analysis showed that
SmTPS
gene family members exhibited tissue-specific expression, and 24 of them responded to exogenous methyl jasmonate.
Conclusion
2
Based on the published
S. miltiorrhiza
genome, 52
SmTPS
gene family members were identified, and their functions were predicted based on the phylogenetic analysis and expression patterns. This paper provides reference information for the further biosynthesis pathway and regulatory mechanism analysis of terpenoids in
S. miltiorrhiza.
