Description	The life cycle of animals and plants involves changes in chromosome number (nuclear phase) and sometimes even the karyotype, and consequently the DNA content of a nuclear genome is not static in time. Thus, in order to interpret DNA content data, it is important that the status of the materials from which DNA content is estimated be precisely defined. The previously proposed distinction between %22holoploid%22 (C) and %22monoploid%22 (Cx) genome size covers the most frequent states of plant and animal nuclear genomes. However, restricting nomenclature to just C and Cx still leaves a number of unresolved problems. Here, we propose an extension of the C-value terminology to handle a range of cytogenetic conditions, life cycle segments, and nuclear phases. A set of superscripts and subscripts are used in a formal way to identify life cycle segments and to express the quantitative relationship between these segments.
