The FvCYP714C2 gene plays an important role in gibberellin synthesis in the woodland strawberry

Background Fragaria vesca, the woodland strawberry, is a diploid relative of the cultivated strawberry. A GA-deficient mutant was found in ethyl methanesulfonate (EMS)-mutagenized lines of the Fragaria vesca accession 'Yellow Wonder'. Objective CYP714C2 was found to be differentially expressed using RNA-seq analysis. It is necessary to identify the function of this gene. Methods In order to identify the function of this gene, it was cloned and transformed into Arabidopsis thaliana. Results The DNA sequence of CYP714C2 was found to be 1940 bp in length, with an open reading frame (ORF) of 1539 bp that is predicted to encode a protein of 512 amino acids. The hydrophilicity of this protein is low and it is unstable. The highest relative expression of FvCYP714C2 was found in the leaves, followed by the pedicels, and low expression levels were found in the other tissues examined. Constitutive expression of FvCYP714C2 significantly promoted the growth of transgenic A. thaliana plants; transgenic Arabidopsis plants grew faster and grew well than wild type Col-0 plants. GA(1+3) contents of the genetically modified Arabidopsis lines were significantly higher than that in the wild type. Conclusion We conclude that FvCYP714C2 is a gene that functions in the gibberellin biosynthesis pathway in strawberry.

Automated summary

The CYP714C2 gene plays an important role in strawberry, as demonstrated by transgenic Arabidopsis experiments showing its ability to promote plant growth and increase GA(1+3) levels.
