Invertase inhibitors have been isolated and partially purified from red beets, sugar beets, and sweet potatoes. These inhibitors are thermolabile proteins with molecular weights of 18,000 to 23,000. They do not inhibit yeast and Neurospora invertases, but they are reactive with potato tuber invertase and other plant invertases with pH optima near 4.5. There are differences in reactivity of the ...

Aquaporins (AQPs) are essential channel proteins that execute multi-functions throughout plant growth and development, including water transport, uncharged solutes uptake, stress response, and so on. Here, we report the first genome-wide identification and characterization AQP (BvAQP) genes in sugar beet (Beta vulgaris), an important crop widely cultivated for feed, for sugar production and for...

The yield of sugar beet has continuously increased in the past decades. The question arises, whether this progress will continue in the future. A key factor for increasing yield potential of the crop is breeding progress. It was related to a shift in assimilate partitioning in the plant toward more storage carbohydrates (sucrose), whereas structural carbohydrates (leaves, cell wall compounds) u...

in order to study the effect of organic fertilizers application on increasing nitrogen efficiency and also quantitative and qualitative characteristics of sugar beet, a series of experiments were performed for two years (2008 and 2009) using three amino acid containing organic fertilizers at motahari research station of sugar beet seed institute (sbsi), karaj, iran. four rates of organic fertil...

UNLABELLED SUMMARY Taxonomy: There are three members of the genus Polerovirus (family Luteoviridae) that induce yellowing of sugar beet: Beet mild yellowing virus (BMYV), Beet chlorosis virus (BChV) and Beet western yellows virus-USA (BWYV-USA, Fig. 1). Non-beet-infecting isolates of BWYV found particularly within Europe have now been re-named Turnip yellows virus (TuYV). Species-specific antib...

sensivity of seed germination stage to saline soil is the main obstacle to proper field establishment of sugar beet crop. in previous studies different tissues of sugar beet showed high tolerance to salt stress by of increasing sodium chloride levels in in vitro condition. an experiment was by to study the response of sugar beet zygotic embryos to salt stress in in vitro conditions. sterile per...

it is well known that sugar beet is sensitive to salinity stress at the germination stage. three separate experiments were conducted to study the effects of salinity on seed germination, plant establishment, and yield of sugar beet genotypes for screening purposes. these included: (a) a laboratory study using four water salinity levels (with ec values < 0.1 as the control, 16, 20, and 24 ds m-1...

introduction sugar beet (beta vulgaris l.) as the second most important world’s sugar source after sugarcane is one of the major industrial crops. the presence of weeds in sugar beet fields, especially at early growth stages, results in a substantial decrease in the crop yield. it is very important to efficiently eliminate weeds at early growing stages. the first step of precision weed control ...

in order to  study the effect of beet mosaic virus on sugarbeet seed yield, an isolate of beet mosaic virus was collected from sugarbeet fields in karaj and biologically was purified by inoculation on chenopodium amaranticolor and propagated on beta vulgaris cv. cicla under greenhouse conditions. the infected sap was inoculated on leaves of  sugar beet  7233 variety at  two stages, after and be...
