Cadmium (Cd) is one of the most toxic non-essential and mobile metallic elements found in soils which affects plant growth. A greenhouse experiment was carried out to determine the genotypic differences in effects of different levels of Cd application on yield and on the uptake of Cd and other nutrients in various Brassica plant parts. The B. juncea (Indian mustard) genotypes produced higher bi...

In order to test the suitability of using Brassica juncea for the remediation by phytoextraction of soils contaminated with U and Ra, the transfer process to the plant was studied. A soil with high natural uranium mineralization was used for the study. When the soil was not manipulated, the transfer factor (TF) was 0.24 ± 0.02 and 1.5 ± 0.3 for U and Ra, respectively. These low values, especial...

The content of arsenic (As), a naturally occurring toxic element found in soils worldwide, has gone substantially high in agricultural soils due to various anthropogenic activities. The responses of seed germination, seedling growth, photosynthetic pigments and the components of the ascorbateglutathione (AsA-GSH) pathway were analyzed in Indian mustard [Brassica juncea (L.) Czern.] cultivar Pus...

Mustard leaf (Brassica juncea (L.) Czern.) using as material of a traditional fermented vegetable food (Kimchi) in Korea, is one of the important vegetables. Two cultivars of mustard (red and green) were grown in the experimental farm of Chungnam National University and allowed them to grow until flowering stage. In this study, the variability of γ-aminobutyric acid (GABA) content and mRNA tran...

Cytoplasmic male sterility (CMS) is universally utilized in cruciferous vegetables. However, the Chinese cabbage hau CMS lines, obtained by interspecific hybridization and multiple backcrosses of the Brassica juncea (B. juncea) CMS line and Chinese cabbage, show obvious leaf etiolation, and the molecular mechanism of etiolation remains elusive. Here, the ultrastructural and phenotypic features ...

Crucifer-feeding flea beetles, Phyllotreta spp., are chronic insect pests in Canadian prairie canola production. Multiple laboratory and field feeding bioassays were conducted to determine the susceptibility of a wide range of crucifer species, cultivars, and accessions to feeding by flea beetles with the goal of discovering sources of resistant germplasm. In 62 bioassays of 218 entries, no con...

Among the different types of methionine-derived aliphatic glucosinolates (GS), sinigrin (2-propenyl), the final product in 3C GS biosynthetic pathway is considered very important as it has many pharmacological and therapeutic properties. In Brassica species, the candidate gene regulating synthesis of 3C GS remains ambiguous. Earlier reports of GSL-PRO, an ortholog of Arabidopsis thaliana gene A...

Wild crucifers namely Arabidopsis thaliana, Brassica fruticulosa, B. rugosa, B. spinescens, B. tournefortii, Camelina sativa, Capsella bursa-pastoris, Crambe abysinnica, Cronopus didymus, Diplotaxis assurgens, D. gomez-campoi, D. muralis, D. siettiana, D. tenuisiliqua, Enatharocarpus lyratus, Lepidium sativum and Sinapis alba along with five cultivated Brassica species including B. rapa (BSH-1)...

An open, continuous flow system was used to investigate ethylene production during degreening of maturing seed of mustard (Brassica juncea cv Cutlass and cv Lethbridge 22A) and canola (Brassica napus cv Westar and cv Alto). Isolated mustard seed evolved higher amounts of ethylene than those of canola, and this was particularly evident both early in embryogeny and later during the desiccation ph...
