Relationship of the Holoploid DNA Content with the Life Form and Duration of Plants’ Life Cycle

The genome size is an important endogenous factor that determines the characteristics of plant growth and development. The holoploid DNA content (C-value) in plants varies over a very wide range. The article analyzes a new Kew Botanical Garden (London, Great Britain) database on the holoploid DNA content in 10 770 species of angiosperms (6633 species of dicots and 4006 species of monocots), which exceeds the previous releases of this database. Clear differences in the holoploid content of DNA between different life forms are shown, and correlations between C-values and other processes, especially life cycle rates, are provided. These correlations are ambiguous and depend on a complex combination of different factors, such as origin and climatic conditions.
