Acetyl-coenzyme A carboxylase (ACCase) occurs in at least two forms in rapeseed (Brassica napus): a homomeric (HO) and presumably cytosolic isozyme and a heteromeric, plastidial isozyme. We investigated whether the HO-ACCase of Arabidopsis can be targeted to plastids of B. napus seeds. A chloroplast transit peptide and the napin promoter were fused to the Arabidopsis ACC1 gene and transformed i...

Experiments were conducted to evaluate the nutritional value of meal derived from low glucosinolate cultivars of mustard (Brassica juncea) in comparison to samples of canola meal (Brassica napus, Brassica rapa). Samples of Brassica seed (four B. juncea, one B. napus, and one B. rapa) were processed using laboratory procedures to produce oil-extracted meals, which were examined for composition (...

An in vitro method was developed for high frequency shoot regeneration and continuous production of Brassica napus L. in large number. The different concentrations of benzyladenine (1.5, 3.0 and 4.5 mgl and thidiazuron (0, 0.15 and 0.30 mgl) were evaluated for shoot and root regeneration using hypocotyl explants with 7, 14 and 21 days old. Shoot regeneration (SR) was affected by both benzyladen...

A method for transformation of B.napus is presented in this study. The protocol is based on infection of cotyledonary petioles of 5-day-old and hypocotyl segments of 14-day-old seedlings with an Agrobacterium tumefaciens strain LBA 4404 carrying a disarmed binary vector pBI121. The T-DNA region of this binary vector contains the neomycin phosphotransferase II (NPTII) and glucuronidase (GUS) gen...

This article presents the results of research on production mutant doubled haploids turnip rape (Brassica rapa L.ssp.Oleifera), as well its interspecies hybrids with rapeseed napus). An  immature embryo culture  was used to increase productivity inter-specific hybridization. Studies have obtained interspecific rapeseed. The largest number plants observed in where mother plant Furtherm...

Canola (Brassica napus L.) is one of the important sources of vegetable oils and protein-rich meals. Canola ranks third in global production of oilseed crops and fifth among economically important crop next to wheat, rice, maize, and cotton. The present work was undertaken with the aim to investigate the effect of Ethylmethyl sulphonate (EMS) on the yield contributing characters of brassica nap...
