We describe a method combining fluorescence-activated cell sorting (FACS) with one-step miniaturized isolation and accurate quantification of cytokinins (CKs) using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) to measure these phytohormones in specific cell types of Arabidopsis thaliana roots. The methodology provides information of unprecedented resolution about spatial distributions of CKs, and thus should facilitate attempts to elucidate regulatory networks involved in root developmental processes.
