A Mechanosensitive Channel in Whole Cells and in Membrane Patches of the Fungus Uromyces
Abstract
Bean leaf stomata provide a topographical signal that induces germlings of the phytopathogen Uromyces appendiculatus to develop specialized infection structures. Protoplasts from germ tubes of this fungus, when examined with patch-clamp electrodes, displayed the activities of a 600-picosiemen mechanosensitive ion channel. This channel passes a variety of cations, including Ca 2+ , and is blocked by Gd 3+ at 50 micromolar. This channel could transduce the membrane stress induced by the leaf topography into an influx of ions, including Ca 2+ , that may trigger differentiation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
