4 results about "Petunia hybrida" patented technology

The invention provides a promoter pchsA derived from petunia, a gene expression cassette of betacyanin and application of the gene expression cassette, and belongs to the technical field of plant genetic engineering. The nucleotide sequence of the promoter pchsA is shown as SEQ ID No.1; according to the invention, a petunia organ specific promoter pchsA is utilized to construct a gene expression cassette of the betacyanin, so that heterologous synthesis of the betacyanin is successfully driven in tobacco, and expression and accumulation of the betacyanin in tissues of roots, stems, leaves and flowers of the tobacco are realized. According to the invention, a new transgenic tobacco germplasm capable of efficiently accumulating the betacyanin is created, a new material is provided for plant bioreactor production of the high-value pigment (betacyanin), and meanwhile, a method for rapidly, intuitively and visually detecting the activity of the promoter is established.

This invention relates to the field of plant genetic engineering technology, specifically to a knockout method. PhAGL17 Application of genes in improving petunia traits. This invention is the first to discover that knocking out wild-type petunias... PhAGL17 Genes can significantly reduce plant height and increase calyx size, which helps control the overall compact shape of the plant and beautify the landscape.

The invention discloses application of a protein or gene for regulating and controlling petunia discoloration in regulating and controlling petunia discoloration and a cultivation method, and belongs to the technical field of plant genetic engineering. According to the invention, a gene PH7 for regulating the color change of petunia is cloned from petunia, and belongs to ERD6L family protein. A CRISPR / Cas9 gene editing system is utilized to obtain a PH7 gene knockout strain, the petal color of the obtained PH7 gene knockout strain is not obviously different from that of a wild type in the early flower development stage and the just blooming stage, but the petals of the knockout strain start to appear blue plaques 2-3 days after blooming, and gradually and completely become blue along with the progress of the flower development stage, and the petals of the knockout strain become blue. The PH7 gene plays an important role in regulating and controlling the formation of the petunia petunia color-changing flowers. The invention provides a new thought for the molecular mechanism research of petunia hybridoma flower formation regulation, and provides a new target for the cultivation of a new variety of petunia hybridoma flowers.
