Extraction of Apoplastic Bacteria Using a Syringe-Based Pressure Method

Source: Rufián, J. S., et al, Single-Cell Analysis of the Expression of Pseudomonas syringae Genes within the Plant Tissue. J. Vis. Exp. (2022)This video demonstrates a syringe-based pressure method for extracting apoplastic bacteria, which proliferate and form microcolonies within the apoplast, the intercellular space between plant cells. The method yields debris-free bacterial samples suitable for downstream single-cell analysis.
