Figure Lengend Snippet: TPEN increases intracellular zinc levels. A. parasiticus wild-type SU-1 spores were center inoculated onto solid GMS media with and without 200 μM TPEN and were grown at 30 °C for 5 days. Plugs containing fungal colony and media were taken from GMS with and without TPEN and incubated with 10 μL Zinpyr-1 (5 μM) probe for 30 min at 37 °C and examined under a fluorescent microscope. The stained cells were observed under the fluorescent microscope as described in Methods. The accumulation of green fluorescent Zinpyr-1 probe was detected within the intracellular matrix of fungal mycelia. Bar 10 μm.
Article Snippet: Under minimal light exposure, the plugs were placed into a two-chambered cover glass microscope slide (Thermo Scientific Lab-Tek II, Waltham, MA, USA) and 10 μL of the probe or DMSO control was pipetted immediately on to the plug.
