ABSTRACT
Objective:
To analyze the differences in protein of thallus of Huperzia serrata (in vitro cultures, strains A, B, and C, respectively) with different Hup A content, and to explore related enzymes that may be synthesized with Hup A accumulation.Methods:
Quantitative proteomics was performed in vitro cultures of Huperzia serrata with different Hup A content using quantitative proteomics tandem mass tag (TMT) techniques, followed by differential proteinanalysis:
GO, KEGG and other biological information analysis.Results:
Strain B hadthe lowest Hup A content and strain C had the highest Hup A content, which was twice than that of B. There were 78 differential proteins between the strain B and C. Analysis of differential protein GO enrichment showed that MF accounted for 28.75%; Analysis of differential protein expression showed that three strains shared two differential proteins (P93541, Q8RXU4) in the alkaloid metabolic pathway starting from amino acids. P93541 protein was down-regulated in the low-yield strain B and up-regulated in the relatively high-yield strains A and C. The Q8RXU4 protein was up-regulated in the low-yield strain B and down-regulated in the relatively high-yield strains A and C.Conclusion:
This study found that the difference in Hup A content was positively correlated with the protein expression. Two enzymes P93541 and Q8RXU4 that may be related to Hup A accumulation were analyzed, providing a basis for bioinformatics analysis of Hup A biosynthesis.
