Levy, M.; Rachmilevitch, S.; Abel, S.; Transient Agrobacterium-mediated gene expression in the Arabidopsis hydroponics root system for subcellular localization studies Plant Mol. Biol. Rep. 23, 179-184, (2005) DOI: 10.1007/BF02772708

To a great extent, the cellular compartmentalization and molecular interactions are indicative of the function of a protein. The development of simple and efficient tools for testing the subcellular location of proteins is indispensable to elucidate the function of genes in plants. In this report, we assessed the feasibility ofAgrobacterium-mediated transformation of hydroponically grown roots to follow intracellular targeting of proteins fused to green fluorescent protein (GFP). We developed a simple in planta assay for subcellular localization of proteins inArabidopsis roots via transient transformation and tested this method by expressing a GFP fusion of a known nuclear protein, IQD1. Visualization of transiently expressed GFP fusion proteins in roots by means of confocal microscopy is superior to the analysis of green tissues because the roots are virtually transparent and free of chlorophyll autofluorescence.
