Boosting Gene Editing Success in Plants with Special Proteins

This patent describes how to make genetic changes in plant cells much more successful by adding specific 'booster' proteins or their genetic instructions alongside the gene-editing tools.

What it covers

This patent details methods for significantly improving the success rate of genome engineering in plant cells. It achieves this by introducing specific 'booster polypeptides' (proteins) identified by amino acid sequences like SEQ ID NO: 2 or 48, or nucleic acids (DNA/RNA) that encode these boosters, into the plant cell. These boosters are delivered along with the desired new gene (transgene) or genome engineering components. For example, if a scientist wants to insert a gene for pest resistance into a corn plant cell, adding these booster proteins would make that insertion process much more efficient, leading to more successfully modified cells. The method can also include other helper polypeptides like PLETHORA 5 (PLT5) or PLETHORA 7 (PLT7) to further enhance the modification process.

What it doesn't cover

• —Does not cover genome engineering or genetic modification in non-plant cells, such as animal or human cells.
• —Does not cover genetic modification methods that do not use the specific booster polypeptides of SEQ ID NO: 2 or 48, or sequences at least 93% identical to them.
• —Does not cover the genome engineering components themselves, only their use in combination with the specified booster polypeptides.
• —Does not cover methods where the booster polypeptide or its encoding nucleic acid is not introduced into the plant cell.
• —Does not cover genetic modification without the goal of increasing efficiency via these specific boosters.

The clever bit

The clever bit is the discovery that specific, identified polypeptides, when introduced into plant cells, act as powerful 'boosters' to dramatically increase the success rate of gene editing and the stable integration of new genes. This addresses a major challenge in plant biotechnology, where the efficiency of genetic modification has often been a limiting factor.

Why it matters

Improving the efficiency of genetic modification in plants is crucial for developing new crop varieties more quickly and cost-effectively. This technology can help scientists create plants that are more resistant to diseases, pests, or harsh environmental conditions like drought, or plants with improved nutritional value. This directly impacts global food security, agricultural productivity, and the ability to adapt crops to changing climates.
