Localization of the stress protein SP21 in indole-induced spores, fruiting bodies, and heat-shocked cells of Stigmatella aurantiaca.

By H Lünsdorf, H U Schairer and M Heidelbach

Abstract

The localization and distribution of the stress protein SP21 in indole-induced vegetative cells, fruiting bodies, and heat shocked cells of Stigmatella aurantiaca were determined by immunoelectron microscopy. SP21 was found at the cell periphery in heat-shocked cells and either at the cell periphery or within the cytoplasm in indole-induced cells, often concentrated in clusters. In fruiting-body-derived spores, SP21 was located mainly at the cell wall, preferentially at the outer periphery. Furthermore, SP21 antigen was associated with cellular remnants within the stalk and within the peripheral horizon next to the fruiting body
