Abstract: | Nuclear DNA contents of more than 100 important plant species were measured by flow cytometry of isolated nuclei stained with
propidium iodide.Arabidopsis exhibits developmentally regulated multiploidy and has a 2C nuclear DNA content of 0.30 pg (145 Mbp/1C), twice the value
usually cited. The 2C value for rice is only about three times that ofArabidopsis. Tomato has a 2C value of about 2.0 pg, larger than commonly cited. This survey identified several horticultural crops in
a variety of families with genomes only two or three times as large asArabidopsis; these include several fruit trees (a pricot, cherry, mango, orange, papaya, and peach). The small genome sizes of rice and
the horticultural plants should facilitate molecular studies of these crops. |
