MAP4 and infection: To analyze the mechanical consequences of infection by the necrotrophic fungal pathogen Sclerotinia sclerotiorum, we monitored the 2D kinematics of Arabidopsis deformation in epidermal cells expressing the microtubule-associated protein 4 (MAP4) fused to GFP over 2-h time courses (24 to 26 h post-inoculation (hpi)).
