abstract in order to find out a better and cheaper artificial diet for mass rearing of common green lacewing, chrysoperla carnea, an experiment was conducted using completely randomized design (crd) with 4 replications and 5 observations. in this study were used three diets [a mixture of honey, yeast and distilled water (1:1:1), a mixture of honey, yeast plus extract of angomois grain moth eggs...

The crown gall induced in potato discs by Agrobacterium tumefaciens is becoming largely utilised in screening anti-tumor agents. The present work is showing that beet discs are more adequate for the anti-tumor screening test. In fact, maximal tumor induction was observed on beet discs (87.5%), followed by carrot discs (75%) and potato discs (68.5%). Beet discs present the most sensibility to cr...

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...

In Europe, the framework for sugar beet (Beta vulgaris L.) production was subject to considerable changes and for the future it is expected that sugar beet cultivation might concentrate around the sugar factories for economic reasons. Based on data from a national sugar beet farmers' survey and multi-year crop rotation trials, the effects of cropping interval (number of years in between two sub...

Background: using root beet powder pigments without extract or using organic solvents, to study the stability of pigments in model foods tomato paste, strawberry jam, juice, and burger, and to perform preliminary studies consumer acceptance of model foods containing them. Objective: The overall aim of this study was to use microencapsulation technique to increase the stability of red beet pigme...

The EU sugar industry has a long tradition of maximising the use of co-products arising from the beet processing operation, all of which are used in productive applications. In fact, sugar factories are not only suppliers of sugar, but also produce other products, such as animal feed. All parts of the beet are used and converted into valuable products, without waste. These products are for the ...

Sugar Beet Nematode (SBN), Heterodera schachtii, is one of the most destructive pests of sugar beets worldwide. It is present in all sugar beet growing areas of Wyoming and is particularly severe in fields located in close proximity to processing plants where sugar beets have been grown the longest. This soilborne, parasitic nematode attacks and destroys the small feeder roots of sugar beet pla...

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 ...

Beet necrotic yellow vein virus (BNYVV) and Beet soilborne mosaic virus (BSBMV) are members of the genus Benyvirus (9). Both viruses infect members of the family Chenopodiaceae, most notably sugar beet (Beta vulgaris L.), and are transmitted by the plasmodiophorid, Polymyxa betae (1,2). BNYVV infection causes rhizomania disease in sugar beet (4,21); however, BSBMV infection does not (28). BSBMV...

Creating transgenic plants is invaluable for the genetic analysis of sugar beet and will be increasingly important as sugar beet genomic technologies progress. A protocol for Agrobacterium-mediated transformation of sugar beet is described in this chapter. Our protocol is optimized for a sugar beet genotype that performs exceptionally well in tissue culture, including the steps of dedifferentia...
