Shoot regeneration by CHK genes

KeyGene reference: P208

Invention

Plant regeneration is essential in processes such as genetic modification. The invention provides a method to increase cytokinin-induced shoot regeneration capacity by overexpression of histidine kinases encoded by so-called CHK genes. Shoots from CHK-gene-transformed cells appeared faster and at an increased number.

Benefit

Genome editing technologies are rapidly emerging. A bottleneck in plant genome editing is the capacity of edited plant cells to regenerate into fertile and healthy plants. Especially for recalcitrant plant species, the fraction of cells successfully regenerating into plants is usually quite low. The patented technology increases the ability of such plants to regenerate, thereby increasing the chance of regenerating plants from edited protoplasts.

Vision

Efficient targeted genome editing technologies are important research tools in gene validation and may be used for the introduction of new traits in crop germplasm. By improving the regeneration capacity of plant cells that may be edited, the present invention contributes thereto.
