How plant pollen could speed development of higher yielding CRISPR-edited crops

| | March 5, 2019

The genome editor CRISPR has transformed many areas of biology, but using this tool to enhance certain varieties of crops such as wheat and corn remains difficult because of the plants’ tough cell walls. Now, a major agricultural company [called Syngenta] has creatively solved that problem by using pollen from one genetically modified plant to carry CRISPR’s components into another plant’s cells. The solution promises to speed the creation of better and more versatile crops, scientists say.

[Syngenta] researchers led by plant biologists Timothy Kelliher and Qiudeng Que….fashioned a way around this problem by exploiting an odd phenomenon known as haploid induction, which allows pollen to fertilize plants without permanently transferring “male” genetic material to offspring. The newly created plants only have a female set of chromosomes….Haploid induction by itself can lead to increased breeding efficiency and higher yielding plants.
