DNA base composition (GC content) is an important genomic and systematic character describing the proportion of nucleotides in the genome. GC content may vary with various structural and functional properties of genomes as shown namely in bacteria and vertebrates. The knowledge of GC content in plants in plants are still very poor in this respect and estimates of GC content are lacking in numerous groups such as in mosses and ferns. The main goal of this project is to detect differences and major trends in base composition among and within the five major evolutionary lineages of land plants (i.e., mosses, club mosses, ferns s.l., gymnosperms, angiosperms). A special interest is aimed to be paid to the ecological and evolutionary significance of being GC-poor or GC-poor not being tested in plants up to date, and to standardization of GC content measurements in plants.
