the influence of salinity on the different polyamine fractions (free, conjugated, and bound) was compared in a natrophilic halophyte (beta vulgaris l. cv. ic) and a salt sensitive glycophyte (nicotiana rustica l. cv. basmas). low-level salinity (25 mm nacl) and high salinity (150 and 50 mm nacl for sugar beet and tobacco, respectively) were supplied in hydroponics. under low salinity shoot dry ...

in 2006 the sugar beet crop production iniranwas largest ever.  in this year, 6,603,383 t with average sugar content of 16.84% delivered to the 32 sugar factories during five months of the campaign. from begining of the campaign until early–november there was balance between the amount of sugar beet delivered and that of processed by the sugar factories.  however, delivered beet to the factorie...

BACKGROUND Modification of leaf traits in sugar beet requires a strong leaf specific promoter. With such a promoter, expression in taproots can be avoided which may otherwise take away available energy resources for sugar accumulation. RESULTS Suppression Subtractive Hybridization (SSH) was utilized to generate an enriched and equalized cDNA library for leaf expressed genes from sugar beet. F...

Sugar beet (Beta vulgaris L. ssp. vulgaris) is one of the most important European crops for both food and sugar production. Crop improvement has been developed to enhance productivity, sugar content or other breeder's desirable traits. The introgression of traits from Crop Wild Relatives (CWR) has been done essentially for lessening biotic stresses constraints, namely using Beta and Patellifoli...

Beet necrotic yellow vein virus (BNYVV) is a member of the genus Benyvirus (21,22) and causes the disease known as rhizomania. It often is reported to be the most important sugar beet (Beta vulgaris L.) virus (17). BNYVV is transmitted by the plasmodiophorid, Polymyxa betae Keskin (1,2,6). In the United States, the virus first was identified in California in 1984 (5) but now occurs in every maj...

BACKGROUND Intermediates from processing sugar beets are considered an attractive feedstock for ethanol fermentation due to their high fermentable sugar content. In particular, medium prepared from raw sugar beet juice seems to be suitable for use in fermentation processes, but it is microbiologically unstable and requires sterilization. RESULTS This study investigates the effect of ozone tre...

Polymyxa betae is a biotrophic obligate sugar beet parasite that belongs to plasmodiophorids. The infection of sugar beet roots by this parasite is asymptomatic, except when it transmits Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania. To date, there has been little work on P. betae–sugar beet molecular interactions, mainly because of the obligate nature of the parasite ...

Molasses is a significant by-product of sugar beet or sugar cane refining industry. In this work, the effects of storage temperature and packaging on the contents of free amino acids (AAs) in sugar beet and sugar cane molasses after freeze drying were inquired. The effect of different variables such as, temperature (4 and 25˚C) and light (Metallized polypropylene container and Normal polypropyl...

Exogenously supplied indole-3-acetic acid (IAA) stimulated ethylene production in tobacco (Nicotiana glauca) leaf discs but not in those of sugar beet (Beta vulgaris L.). The stimulatory effect of IAA in tobacco was relatively small during the first 24 hours of incubation but became greater during the next 24 hours. It was found that leaf discs of these two species metabolized [1-(14)C]IAA quit...
