Description Our understanding of genome organization has its roots in postwar interest in
the effects of radiation. Observations on the relationship between doses of
ionizing radiation and the frequency of mutations (Abrahamson et ai., 1 973;
Trujillo and Dugan, 1 975) indicated that the size of the genetic target
receiving the radiation dose varied considerably between organisms. By the
beginning of the 1 970s, this phenomenon had come to be known as the "Cvalue
paradox" (Thomas, 1 97 1 ). The paradox was that the total genome size,
or C-value, varied widely within a given clade of organisms and bore no
relationship to organismal complexity. For example, two legumes within the
same genus, Vida/aba and Vida sativa, have haploid genomes of 1 3. 1 x 1 09
and 2.2 x109 respectively, but differ very little morphologically. This
observation has been fully confIrmed by the large-scale determination of
genome sizes of many plants (http://www. rbgkew.org.uk/cvalues), within
which genome size varies from about 107 bp in Cardamine and Arabidopsis
among the Crucifereae to nearly 1 011 bp in Fritillaria among the Lilliaceae.
Within the cereals, rice (Oryza sativa) has a compact genome of 4.8 x 1 08 bp,
ranging upwards through sorghum (7.35 x 1 08), maize (26.7 x 1 08), and
barley (54.4 x 1 08 bp)......
