[0027] Cloning of Soybean OLEOSIN2 Gene and Construction of Expression Vector

[0028] 1. Acquisition of the target gene

[0029] 1. Obtain the sequence of the OLEOSIN2 gene on the Soybase website (https: / / www.soybase.org / ), and use the NCBI primer blast website (https: / / www.ncbi.nlm.nih.gov) to design the primer OLE according to the transcriptome sequence -F and OLE-R.

[0030] OLE-F: ACACACCCCACTAACAATTCC

[0031] OLE-R:AGACACGAACGAACGTCCCCTAC

[0032] 2. Using the cDNA of Williams 82 as a template, using RT-PCR technology to clone the OLEOSIN2 gene ( figure 1 ), the PCR product was recovered with TIANgel Midi Purification Kit after 1% agarose gel electrophoresis. The specific operation was carried out according to the instructions of the kit.

[0033] 3. Use the instrument to measure the concentration of the recovered product, and adjust the volume of the added fragment and TAKARA PMD-18T carrier reasonably according to the range of the fragment and carrier molar conc...

Abstract

The invention discloses a construction method and application of an agrobacterium Ti plasmid vector PCHF1302 and belongs to the technical field of plant genes. Double enzyme digestion is simultaneously conducted on enzyme digestion sites ECORI and HindIII on an agrobacterium Ti plasmid Pcambia 1302, wherein the PCHF3300 comprises a 35S promoter, a NOS terminator and a complete gene expression frame of MCS, a homologous arm is added through PCR, an expression frame started by the 35S promoter is successfully connected to the plasmid Pcambia 1302, and the PCHF1302 is constructed; the target genecloned by PCR and other methods can be conveniently connected to a plurality of cloning enzyme digestion sites (MCS), so that the target gene can be stably expressed in plants; a TDNA region containing hygromycin resistance gene and mGFP5 green fluorescent protein reporter gene can significantly improve the screening effect of transgenic plants.

Description

technical field [0001] The invention belongs to the technical field of plant genes, and in particular relates to a construction method and application of an Agrobacterium Ti plasmid vector PCHF1302. Background technique [0002] In recent years, plant genetic engineering technology has developed rapidly, especially transgenic technology plays a key role in the study of gene function. Through transgenic technology, we can transfer the gene to be studied into the source plant of the gene or other model plants to study the gene function. The construction of the gene expression vector needs to be completed before the transgenesis. However, the commonly used plant expression vectors have various defects. For example, Pcambia1301 and Pcambia1302 lack the 35S promoter and terminator for the expression of the target gene, so they cannot be directly used to construct gene expression vectors. Contents of the invention [0003] The object of the invention is to provide a method fo...
