title: A Simplified and Rapid Method for the Isolation and Transfection of Arabidopsis Leaf Mesophyll Protoplasts for Large-Scale Applications.
abstract: Arabidopsis leaf mesophyll protoplasts constitute an important and versatile tool for conducting cell-based experiments to analyze the functions of distinct signaling pathways and cellular machineries using proteomic, biochemical, cellular, genetic, and genomic approaches. Thus, the methods for protoplast isolation and transfection have been gradually improved to achieve efficient expression of genes of interest. Although many well-established protocols have been extensively tested, their successful application is sometimes limited to researchers with a high degree of skill and experience in protoplasts handling. Here we present a detailed method for the isolation and transfection of Arabidopsis mesophyll protoplasts, in which many of the time-consuming and critical steps present in the current protocols have been simplified. The method described is fast, simple, and leads to high yields of competent protoplasts allowing large-scale applications.
