(During the late Soviet era the Belorussian S.S.R. produced about one-fourth of the U.S.S.R. total). Potatoes, sugar beets, barley, wheat, rye, and corn (maize) are other important field crops; a large percentage of the grains are used for animal feed.
This gene density would suggest a total number of sugar beet genes of more than 80,000, an apparent overestimation compared to the total gene numbers of other dicots such as Arabidopsis (25,498), black cottonwood (Populus trichocarpa Torr. & A.Gray; 45,555), and grapevine (Vitis vinifera L.; 30,434) (The Arabidopsis Genome Initiative 2000; Tuskan et al. 2006; Jaillon et al. 2007).
Thus, the economic benefit would be €1.3 million, or ∼2% of the total value of sugar beet production.
If GM crops enjoyed full public acceptance, and if there were accordingly no costs of separation, the economic gain to society would amount to €10 million; about 14% of the total value of sugar beet production.
A total of 502 diploid sugar beet inbreds from the pollen parent heterotic pool were examined in this study.
Neither assay produced PCR products using total RNA extracted from the roots of healthy sugar beet or beet infected with Beet soil-borne virus.
Here, this generated a total of 6.6 Gb of sugar beet transcript sequences.
We analyzed a total of n = 178 sugar beet inbreds of the pollen parent heterotic pool, proprietary to KWS SAAT AG (Einbeck, Germany).
Notwithstanding the possibility that some of these loci could be the result of mis-assemblies, our data may now have expanded the total known gene count of sugar beet by up to 40%.
Total RNA from sugar beets was isolated according to Chomczynski and Sacchi (1987) or by using the RNeasy Plant Mini kit (Qiagen, Hilden, Germany).
