4th Edition Of Plant Science and Molecular Biology World Conference 2027

Genome editing in plants is moving into a new phase with base editing, prime editing and epigenome editing, and this PMBWC 2027 session covers the tools and applications driving that change. Genome editing in plants has moved beyond simple gene knockouts. Base editing changes a single DNA base, prime editing can insert or replace short sequences, and epigenome editing changes gene activity without altering the DNA sequence. These tools allow more precise and predictable crop improvement. These methods can be used to improve traits such as yield, quality, disease resistance and tolerance to stress, often by making very small changes to existing genes. Many countries are reviewing their rules for gene-edited crops, and plants that carry no foreign DNA are being treated differently from traditional genetically modified crops in several regions. This is creating new opportunities for research and commercial use.

This session covers new editing tools, CRISPR activation and interference, delivery methods that do not leave foreign DNA in the plant, and examples of edited crops. It also discusses the regulation of gene-edited plants and the steps needed to bring edited varieties to farmers.

Key Topics Covered

• Base editing and prime editing in crops
• CRISPR activation (CRISPRa) and interference (CRISPRi)
• Epigenome editing for gene regulation
• DNA-free and transgene-free delivery methods
