Abstract
Cisgenesis is genetic modification to transfer beneficial alleles from crossable species into a recipient plant. The donor genes transferred by cisgenesis are the same as those used in traditional breeding. It can avoid linkage drag, enhance the use of existing gene alleles. This approach combines traditional breeding techniques with modern biotechnology and dramatically speeds up the breeding process. This allows plant genomes to be modified while remaining plants within the gene pool. Therefore, cisgenic plants should not be assessed as transgenics for environmental impacts.
Highlights
Increasing world population and food demands require world agricultural production be increased by 50% by 2030 (The Royal Society, 2009)
Increasing numbers of these cisgenes have been isolated and new transformation protocols have been developed, which do not leave marker genes behind. This allows plant genomes to be modified while remaining plants within the gene pool. This new breeding approach was first called cisgenesis by Schouten et al (2006), who defined a cisgenic plant as “a crop plant that has been genetically modified with one or more genes isolated from a crossable donor plant.”
In the scientific opinion of the [European Food Safety Authority (EFSA), 2012], cisgenesis is described as specific alleles/genes in the breeder’s gene pool are introduced into new varieties without the accompanying linkage drag which occurs in conventional breeding
Summary
Increasing world population and food demands require world agricultural production be increased by 50% by 2030 (The Royal Society, 2009). Traditional plant breeding uses crossing, mutagenesis and somatic hybridization for genome modification to improve crop traits.
