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'.
CYP714C2 was found to be differentially expressed using RNA-seq analysis. It is necessary to identify the function of this gene.
In order to identify the function of this gene, it was cloned and transformed into Arabidopsis thaliana.
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 contents of the genetically modified Arabidopsis lines were significantly higher than that in the wild type.
We conclude that FvCYP714C2 is a gene that functions in the gibberellin biosynthesis pathway in strawberry.
林地草莓( Fragaria vesca )是栽培草莓的二倍体近缘种。在乙基磺酸甲酯(EMS)诱变的林地草莓‘Yellow Wonder’品系中发现了一个赤霉素缺乏突变体。
使用 RNA-seq 分析发现 CYP714C2 表达差异。需要确定该基因的功能。
为了鉴定该基因的功能,将其克隆并转化入拟南芥。
CYP714C2 的 DNA 序列长 1940bp,开放阅读框(ORF)长 1539bp,预测编码 512 个氨基酸的蛋白质。该蛋白的亲水性低,不稳定。FvCYP714C2 的相对表达量最高的组织是叶片,其次是花梗,其他组织的表达量较低。FvCYP714C2 的组成型表达显著促进了转基因拟南芥植物的生长;与野生型 Col-0 植物相比,转基因拟南芥植物生长更快,生长状况良好。转基因拟南芥株系的赤霉素含量明显高于野生型。
我们得出结论,FvCYP714C2 是草莓赤霉素生物合成途径中的一个基因。
