Chinese Scientists Develop Simple Plant Gene Editing Tool For Local Farmers

Must Read

News in brief:
– Chinese scientists at SUSTech have developed a simplified gene editing method, making it accessible to students and farmers.
– The innovative “cut-dip-budding” approach bypasses traditional tissue culture, offering potential benefits for agriculture by enhancing crop productivity and resilience.

Chinese scientists, led by Zhu Jian-Kang, have developed an innovative method for genetic transformation and gene editing, significantly simplifying the intricate process of editing genes in plants. This breakthrough holds the potential to democratize gene editing, reducing the time-consuming task to a mere two weeks.

Traditional methods of heritable gene editing in plants pose significant challenges, often taking months or even up to a year and requiring sophisticated knowledge. Cao Xuesong, a scientist from the research team, added that it has a high technological barrier.

CRISPR/Cas and its evolution

The widely used CRISPR/Cas, a third-generation gene-editing tool, has played a transformative role in life sciences. However, its application in plants faces obstacles, including the inefficient delivery of gene-editing tools into plant cells.

Zhu’s team introduced the CDB method, standing for ‘cut-dip-budding,’ a revolutionary approach that skips tedious steps like tissue culture. This three-step process involves cutting a regenerative part of the plant, dipping it into a solution containing Agrobacterium, and regenerating the edited cells without the need for extensive tissue culture.

Widespread application and future prospects

The researchers successfully applied the CDB method to Taraxacum kok-saghyz, a species of dandelion notable for its production of high-quality rubber, demonstrating the tech’s feasibility. Cao mentioned that the team tested the technology on over 20 plant species, indicating its potential as a general-purpose approach in gene editing.

While the initial response from the scientific community has been positive, Cao emphasised the need for further investigation to evaluate the full potential of this method in plant research and agricultural production.
