[Distribution of a betaine lipid O-(1,2-diacylglycero)-N,N,N-trimethylhomoserine in tissues of some Lycopodiophyta species].

The distribution of O-(1,2-diacylglycero)-4'-(N,N,N-trimethyl)homoserine (DGTS), a betaine lipid, in ten samples of plants belonging to the division Lycopodiophyta collected in various habitats was studied. Homogeneous plant tissues (vegetative shoots and spikelets) and mixed tissues (shoots with spikelets) were analyzed. Particular attention was paid to the DGTS-synthesizing ability of various club mosses and to various tissue types forming an organ in a single plant species, as well as the ratio between DGTS and other glycerolipid classes.
