slime cells Photobiology. Neurospora crassa is well known for its blue light receptor system. Many of the genes responsible for blue light signal transduction have been identified. However, ion transport changes are also known to occur almost immediately upon blue light irradiation. To identify blue light regulated ion transport, we used the slime mutant of Neurospora crassa. This mutant lacks the cell wall common to fungi, and indeed, exhibits amoeboid movement, as indicated to the left. This makes it amenable to patch-clamp measurements of ionic currents.
