PIVOT: A New Single-Cell Screening Platform for Plant Functional Genetics
Researchers have developed PIVOT, a novel single-cell screening platform designed to accelerate the functional characterization of plant genes. Published in Nature Biotechnology, this technology addresses significant challenges in plant genetics by enabling the precise delivery of gene libraries to tobacco leaves with a single multiplicity of infection. The system utilizes magnetic sorting to isolate individual plant cells based on specific phenotypic traits, allowing for high-throughput analysis at the single-cell level. In their demonstration, the research team successfully used PIVOT to identify regulators of cytokinin signaling from an Arabidopsis open reading frame library. This advancement represents a significant pivot in plant biotechnology, moving away from labor-intensive, bulk screening methods toward more efficient, resolution-specific functional genomics. By facilitating the rapid recovery of gene regulators, PIVOT offers a powerful tool for understanding complex plant biological processes and could potentially streamline the development of crops with enhanced traits. The study highlights the integration of viral delivery systems and cell sorting technologies to overcome previous limitations in plant genetic screening.
