Four years of grazing trials were conducted with Brassica forages to evaluate their chemical composition and effect on ADG of fattening lambs and breeding ewes in late fall. Brassicas tested included kales (Brassica oleracea L. var. acephala DC), turnips (B. rapa L.), and a chinese cabbage hybrid (B. rapa L. x B. pekinensis [Lour.] Rupr.). Daily gains of lambs varied widely among years (19 to 3...

14-3-3s are highly conserved, multigene family proteins that have been implicated in modulating various biological processes. The presence of inherent polyploidy and genome complexity has limited the identification and characterization of 14-3-3 proteins from globally important Brassica crops. Through data mining of Brassica rapa, the model Brassica genome, we identified 21 members encoding 14-...

—The diamondback moth (Plutella xylostella [L.]), is one of the most economically important pests of cruciferous plants throughout the world, causing economically significant damage in broccoli, cabbage, canola, collards, and mustard. In Canada, P. xylostella is an important economic pest of canola (Brassica napus L. and Brassica rapa L.). In North America, the diamondback moth has been collect...

A mosaic disease of turnip [Brassica rapa L.) occurs on Long Island, N. Y. Typical specimens of this disease were obtained for comparative greenhouse studies with virus diseases affecting certain cultivated crucifers in California {lô, 16,17,18)} It is the purpose of this paper to describe briefly the symptoms of this mosaic disease of turnip from New York, to present experimental evidence on t...

Aquaporins (AQPs) are essential channel proteins that regulate plant water homeostasis and the uptake and distribution of uncharged solutes such as metalloids, urea, ammonia, and carbon dioxide. Despite their importance as crop plants, little is known about AQP gene and protein function in cabbage (Brassica oleracea) and other Brassica species. The recent releases of the genome sequences of B. ...

Stable expression of a transgene may lead to increased fitness for wild plants after acquiring the transgene via crop-weed hybridization. Here, we investigate the stability of Bt toxin content in wild Brassica rapa acquiring the Bt gene from Bt Brassica napus. The Bt toxin content in nine Bt-expressing B. napus lines was 0.80-1.70 micro g/g leaf tissue throughout the growing season. These nine ...

The effect of addition of a microbial consortium (A) with 22 micro-organisms on the large scale (400 m3) bioremediation of municipal waste water contaminated with petroleum hydrocarbons was evaluated. Our results showed that addition of Consortium A was effective in reducing the level of contamination of total petroleum hydrocarbons (TPH) from 1086 mg L-1 to 56 mg L-1after just 21 days and to 1...

We administered foliar applications of 50, 100, and 200 mg L-1 selenium (Se, selenite) on turnip (Brassica rapa var. rapa Linn.) and detected the changes in the main nutrient components in fleshy roots. Results showed that the foliar application of Se (IV) significantly increased the Se content in turnip, and Se (IV) positively affected the uptake of several mineral elements, including magnesiu...

Clubroot disease caused by an obligate biotroph, Plasmodiophora brassicae Woronin, causes damage to cruciferous vegetables. In the breeding of Chinese cabbage (Brassica rapa L. ssp. pekinens is) in Japan, European turnips were fbund to be a source ofclubroot-resistance (CR) genes (Yoshikawa 1981). To date, more than 50 CR Fi cultivars have been bred. However, the breakdown ofthe clubroot resist...
