Construction of recombinant plasmid vector for gene expression is a key step in making transgenic plants and important to study gene function and plant genetic engineering. A right choice of gene construction method can be cost-effective and achieve more diverse recombinant plasmids. In addition to the traditional methods in construction of plant gene expression vectors, such as Gateway technology, three DNA method and one step cloning, a few novel methods have been developed in recent years. These methods include oligonucleotide synthesis-based construction of small fragment gene expression vectors via competitive connection; construction of small RNA expression vector using pre-microRNA; recombination-fusion PCR method which inserts DNA fragments of multiple restriction sites into the target vector; and insertion of a DNA fragment into any region of a linear vector via In-Fusion Kit. Construction of complex vectors with many fragments uses sequence and ligation-independent cloning method, Gibson isothermal assembly or Golden Gate assembly. This paper summarizes our working experience in the area of recombinant vector construction and reports from others with an intention to disseminate ideas about currently widely used DNA recombination methods for plant transformation.
