In planta gene expression analysis and colonization of fusarium oxysporum

Abstract

[EN]In planta gene expression analysis and GFP-based confocal microscopy are two powerful techniques that may be coupled to assess the extent and dynamics of plant colonization by a fungal pathogen. Here we describe methods to prepare common bean plants for inoculation with a highly virulent strain of Fusarium oxysporum f. sp. phaseoli, quantify the extent of colonization by RT-qPCR, and visualize the colonized tissues by confocal microscopy.
