Study Notes

Plant Biotechnology

Single crops often need to meet multiple requirements, including sustainable food and healthful nutrition, environmental protection, and job opportunities.
Developing suitable plants is a complex challenge.

Gene Transfer Process

Involves removing genetic information from an organism, manipulating it in a laboratory, and transferring it into a plant to alter certain characteristics.
Electrical pulses are applied to a suspension of cells with DNA in an electroporation cuvette placed between electrodes.

Gene Transfer Methods

Electroporation method: uses electrical pulses to transfer genes.
Silicon carbide method: uses fibers of organic material like silicon carbide for gene transfer.

Progress in Gene Transfer Technology

Dramatic progress has been made in the development of a gene transfer system for higher plants in the last few years.
About 20 crops can be genetically engineered at present.
