[目的]探究中国樱桃CpM4DS47基因的生物学特性及其在果实成熟软化中的作用。[方法]克隆获得与中国樱桃果实质地相关的MADS-box基因CpMADS47,进行生物信息学分析,异源瞬时过表达草莓果实进行功能验证。[结果]中国樱桃CpMADS47属SEP1/2-like基因,CDS区全长741 bp,编码246个氨基酸。CpMADS47蛋白与蔷薇科物种的亲缘关系较近。瞬时过表达草莓果实表明,CpMADS47通过促进草莓果实硬度降低、花青素苷积累、细胞壁成分解聚和ABA合成从而介导果实的成熟软化。[结论]中国樱桃CpMADS47基因能够促进果实成熟软化,为后续中国樱桃果实质地品质改良奠定理论基础和提供基因资源。
Functional Analysis of the CpMADS47 Gene Regulating Fruit Ripening and Softening in Chinese Cherry
[Objective]This study aims to investigate the biology and role of Chinese cherry CpMADS47 gene during fruit ripening and softening.[Method]The MADS-box gene CpMADS47,which is involved in fruit texture changes in Chinese cherry,was cloned and subjected to bioinformatics analysis.Heterolo-gous transient overexpression of CpMADS47 was performed on strawberry fruits to validate its function.[Result]Bioinformatics analysis revealed that the coding sequence(CDS)of the SEP1/2-like gene CpMADS47 in Chinese cherry consists of 741 base pairs(bp)and encodes a protein of 246 amino acids.Phylogenetic analysis indicated that the CpMADS47 protein exhibits a close evolutionary relationship with MADS proteins from various species within the Rosaceae family.Transient overexpression of straw-berry fruits showed that CpMADS47 mediates fruit ripening and softening by promoting strawberry fruit texture softening,anthocyanin accumulation and ABA biosynthesis.[Conclusion]The CpMADS47 gene promotes fruit ripening and softening,providing a theoretical basis and genetic resource for the genetic improvement of fruit texture quality in Chinese cherry.
