Abstract

The invention discloses a cucumber carotenoid phytoene synthetase gene. All cucumber carotenoids are synthesized by isoprenoid compounds or terpenoids. The length of the nucleotide sequence SEQ ID of the cucumber carotenoid phytoene synthetase gene is 1479bp, and the cucumber carotenoid phytoene synthetase gene has a specific nucleotide sequence. The gene-coded polypeptide of claim 1 comprises 422 amino acids, has the molecular weight of 47393.507Da, the isoelectric point of 6.545, the charge of 0.777 when the pH value is 7.0, and has a specific amino acid sequence. The recombinant plasmid pT-PSY of the gene of claim 1 has the length of 4515bp, comprises ampicillin selection markers, and has a specific nucleotide sequence. The invention is used for cloning cucumber carotenoid phytoene synthetase genes.

Description

Technical field: [0001] The invention relates to the technical field of genetic engineering; in particular, it relates to a gene for cloning cucumber carotenoid phytoene synthase. Background technique: [0002] All cucumber carotenoids are synthesized via the isoprenoid or terpenoid pathway. There are 5 enzymes involved in its metabolic main chain, namely phytoene synthase phytoene synthase gene PSY, phytoene desaturase PDS, ξ-carotene desaturase ZDS, tomato Lycopene β-cyclase LycB and lycopene ε-cyclase LycE. With the development of molecular biology research methods, genes encoding these enzymes have been isolated and identified from tomato, tobacco, pepper, Arabidopsis, corn and other plants. At present, the cloning of the full-length gene of cucumber carotenoid synthase has not been reported at home and abroad. Invention content: [0003] The purpose of the invention is to provide a design sequence of the known phytoene synthase gene PSY of other plants as a primer,...
