Summary
The DNA content of plant nuclei varies by about a thousand-fold. This DNA is contained in chromosomes, the number and size of which in a given species can vary as well. The nuclear DNA contains highly repetitive tandemly arrayed, dispersed repetitive and low copy-number sequences, the last of which comprise most of the genes. Genome size can affect the phenotype irrespective of the information content.
