Embodiment 1

[0038] Embodiment 1 of the present invention is illustrated by taking the genetic transformation of mustard hau CMS cytoplasmic male sterility gene as an example:

[0039] A method for genetic transformation of mustard mediated by Agrobacterium, comprising the steps of:

[0040] 1) Containing the construction of the target gene vector:

[0041] The CaMV35S promoter was connected to the pCAMBIA2300 vector, and the enzyme cutting sites used were HindIII and PstI;

[0042] PS: rfp288 73-288aa Construction of the vector: the signal peptide Rfp and rfp288 were combined by overlapping PCR technology 73-288aa The nucleotide sequences overlapped, and the enzyme cutting sites used include: PstI and BamHI.

[0043] Required primers include:

[0044] d-Rfp-L(PstI): AACTGCAGATGGTGTTGAGGACACAGAGAT;

[0045] d-Rfp-R: TCGTATCAAAGAGATTACCATTCTATCGCTGGTGAGACCAGA;

Abstract

The invention belongs to the technical field of transgenosis and particularly relates to a genetic transformation method of agrobacterium-mediated mustard. The specific method comprises the step of successfully obtaining transgenic positive seedlings through inducing culture callus via co-transformation by taking a mustard hypocotyl subjected to dark culture for 7 days as an explant and utilizing an agrobacterium infection hypocotyl carried with a target gene carrier, performing resistance screening, dedifferentiating and the like. The PCR authentication of the positive seedlings proves that a target gene is successfully transferred to a plant for expression. The invention establishes an efficient regeneration system of mustard, thereby providing a basis for the study on a mustard agrobacterium-mediated transgenic technology.

Description

technical field [0001] The invention belongs to the technical field of plant tissue culture and transgene, and in particular relates to an Agrobacterium-mediated genetic transformation method of mustard. [0002] technical background [0003] Mustard is an annual or perennial herb in the genus Brassicaceae. It is mainly grown as an oil crop and seasoning. Mustard contains abundant germplasm resources, which have very important scientific research value and economic use value. As fresh and processed vegetables, mustard greens mainly include: root mustard, stem mustard, leaf mustard and stalk mustard, which are mainly grown as vegetables in China. Oil crops are mainly seed mustard, which is currently widely planted in arid regions of India, Canada, Australia and other countries. [0004] Since the world's first genetically modified tobacco was successful in 1984, more and more crop genetically modified systems have been successfully established. Among Brassica crops, only t...
