Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
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...

Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Area of Science:

Plant biotechnology
Metabolic engineering
Synthetic biology

Background:

Single-point interventions in plant metabolic engineering often fail to increase target metabolite yields.
Bottlenecks can shift downstream or cause undesirable intermediate accumulation with single interventions.
Coordinated gene expression via regulators is limited by the availability of master regulators.

Purpose of the Study:

To review the state of the art in multigene transformation for plant metabolic engineering.
To highlight recent advances in simultaneously expressing multiple pathway genes in plants.
To emphasize the benefits of removing all metabolic bottlenecks for unrestricted flux.

Main Methods:

Review of current literature on multigene transformation techniques in plants.
Analysis of strategies for simultaneous transfer and expression of multiple enzyme-encoding genes.
Discussion of advances enabling efficient multigene delivery.

Main Results:

Simultaneous expression of multiple genes, especially at critical enzymatic steps, is a robust approach.
Multigene transformation efficiently removes bottlenecks and ensures unrestricted metabolic flux.
Recent advances facilitate the simultaneous transfer of multiple genes into recipient plants.

Conclusions:

Multigene transformation is a powerful strategy for enhancing metabolite production in plants.
Overcoming metabolic bottlenecks through simultaneous gene expression is key to maximizing yields.
Continued advances in this field promise significant progress in plant metabolic engineering.
