Learn how high-throughput microfluidic technology enables single-cell analysis and sorting of plant cells at scale, advancing plant biotechnology research. This study introduces a novel droplet-based platform that can encapsulate and analyze over 100,000 plant protoplasts per hour, quantifying gene expression responses and enabling the selection of transgenic cells based on fluorescence. This approach has vast potential for genetic research, allowing efficient screening of plant phenotypes and synthetic circuits with minimal plant material.
