[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.

[EN]Guanine nucleotide exchange factors (GEFs) are directly responsible for the activation of Rho-family GTPases in response to physical and chemical stimuli and ultimately regulate numerous cellular responses such as polarized growth, morphogenesis, and movement. The GEF proteins are characterized by a Dbl-homology (DH) domain that contacts the Rho GTPases, to catalyzing nucleotide exchange, and an associated Pleckstrin homology (PH) domain, which fine-tunes the exchange process by a variety of mechanisms related to the binding of phosphoinositides. Most GEFs are divergent in regions outside the DH/PH module and contain additional protein-protein or lipid-protein interaction domains that presumably dictate unique cellular functions. Fission yeast Rho1-GEFs act as a link between growth processes and the cell cycle machinery. In this chapter, we focus on the recent leaps in our understanding of how Rho1-GEFs control interphase and cytokinesis in fission yeast. Furthermore, we will go beyond mitosis and highlight the unexpected roles of Rho1-GEFs in the DNA damage response.
