Abstract:
A tandem gene cluster CHS-CHI-IFS (rIFS) for secondary metabolites of plant isoflavones was constructed by using the chalcone synthase (CHS), chalcone isomerase (CHI), and isoflavone synthase (IFS) (GenBank accession numbers EU526827, EU526829, EU526830) in a single recombination event with the pET22b vector. The resulting expression vector pET-rIFS was heterogeneously expressed. The highlights of the vector include ease of handling, high efficiency and universal application among diverse plant species. To the best of our knowledge, this is the first attempt at developing a novel method of constructing tandem gene cluster for future research involving secondary metabolism of isoflavones and isoflavones engineering.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
Combinatorial Gene Control
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
