The occurrence of caulonema-specific proteins in different moss species.

Soluble proteins extracted with Tris-buffer pH 8.8 from different mosses are analysed by microgelelectrophoretic method for comparison to the specific proteins present only in the caulonema of Funaria hygrometrica. The protein patterns are also compared with those of liverwort, fern gametophytes and sporophytes and tobacco. It is observed that the "caulonema specific proteins" are only present in the caulonema of these mosses and are absent in other plants.
