BACKGROUND Hepatitis c virus (HCV), prevalent among 3% of the world population, is a major worldwide public health concern and an effective vaccination could help to overcome this problem. Plant seeds as low-cost vaccine expression platforms are highly desirable to produce antigens. OBJECTIVES The present study was aimed at investigating the possible expression of recombinant HCV core protein...

Canola (Brassica napus L. and B. rapa L.), is one of the major oilseed crops grown worldwide. With significant expansion of acreage sown to canola during the past two decades, concern about blackleg, the most serious disease of canola, has increased (3,4). Blackleg disease is caused by Leptosphaeria maculans (Desmaz.) Ces. & De Not. (anamorph: Phoma lingam (Tode:Fr.) Desmaz.). The pathogen can ...

Canola meal is derived from the crushing of canola seed for oil extraction. Although it has been used in swine diets for a long time, its inclusion levels have been limited due to concerns regarding its nutritive value primarily arising from results of early studies showing negative effects of dietary canola meal inclusion in swine diets. Such effects were attributable to the presence of anti-n...

The effects of four different canola lecithins applied at proportions of 30 g fatty acid kgÿ1 diet were compared with diets containing either no additional lipid or the same amount of fatty acids from canola seed, pure canola oil and deoiled soy lecithin, respectively. Four types of canola lecithin with increasing dispersibility in water were used: raw; deoiled; deoiled/hydrolysed; and hydrolys...

Many biological effects of exposure to extremely low frequency electromagnetic fields(ELF-EMFs) have been documented, but little work carried out on plants. A meiotic study wasperformed on Brassica napus L as C3 plant and Zea mays L as a C4 plant exposed to electromagneticfields. Our investigations were focused on plants grown from wet pretreated seeds with3 and 10 mT for a 4 h exposure time an...

Oilseed crops, particularly canola, Brassica napus L., and B. rapa L., are now a major part of the prairie landscape in Canada. A diverse assemblage of arthropods can be found in areas devoted to oilseed crop production, either feeding on a resource provided by the crop, or feeding on other insects that have been attracted to these areas. Some insects prefer to feed on other plants that are gro...

The seed oil content in oilseed crops is a major selection trait to breeders. In Arabidopsis (Arabidopsis thaliana), LEAFY COTYLEDON1 (LEC1) and LEC1-LIKE (L1L) are key regulators of fatty acid biosynthesis. Overexpression of AtLEC1 and its orthologs in canola (Brassica napus), BnLEC1 and BnL1L, causes an increased fatty acid level in transgenic Arabidopsis plants, which, however, also show sev...

The R2R3-MYB proteins comprise one of the largest families of transcription factors in plants. Although genome-wide analysis of this family has been carried out in some plant species, little is known about R2R3-MYB genes in canola (Brassica napus L.). In this study, we have identified 76 R2R3-MYB genes in the canola genome through mining of expressed sequence tags (ESTs). The cDNA sequences of ...

This experiment was conducted to evaluate the effects of saturated and unsaturated fats in starter and grower feeds on performance and carcass parts of broilers. In this experiment 288 day old broiler chicks (Ross308 strain) were used in a completely randomized design for 42 days with 8 treatments in 3 replicates and 12 chicks in each replicate. The experimental groups included: T1) control gro...

the changes of chl a fluorescence induction curve in response to different salinity levels in canola (barassica napus, l.) plants were investigated. the canola seedlings were exposed to salt stress (100 mm and 200 mm nacl) for 7 days and chl a fluorescence induction kinetics was analysed. by using the ojip-test, various parameters like vj, area, n, φpo, φeo, ψo, rc/abs and piabs were calculated...
