Efficient molecular markers for the selection of rapeseed genetic materials with high seed oil content and ideal fatty acid (FA) composition are preferred by rapeseed breeders. Recently, we reported the molecular mechanism of TRANSPARENT TESTA 2 (TT2) in inhibiting seed FA biosynthesis in Arabidopsis. However, evidence showing the association of rapeseed TT2 homologs and seed FA production are ...

Summary Allelopathic effects of different plant allelochemicals have become the focus studies that aim to determine new pesticidal compounds. Plant extracts with chemical compositions can be obtained using methods extraction, whereas dealing allelopathic properties use biotests obtain fast and precise results. Such were undertaken after noticing industrial hemp (Cannabis sativa L.) on surroundi...

In order to study the effect of Pseudomonas fluorescens on growth, morphological characteristics and phosphate uptake by rapeseed (Brassica napus L. Hyola 401), an experiment was performed in 2010. The study was carried out as a randomized complete blocks design with three replications. The treatments included plants inoculation by Pseudomonas fluorescence strain 11, strain 4, strain 169, the d...

A comparative study was conducted to see the mutational analysis for monounsaturated fatty acids in rapeseed (Brassica napus L.) mutant populations. By using gamma irradiation, a range of variability generated for oil content and fatty acid composition in rapeseed seeds. The induced genetic variability was analyzed for two consecutive years in two contrasting environments at elevations of 510 a...

Male sterility induced by a chemical hybridization agent (CHA) is an important tool for utilizing crop heterosis. Monosulphuron ester sodium (MES), a new acetolactate synthase-inhibitor herbicide belonging to the sulphonylurea family, has been developed as an effective CHA to induce male sterility in rapeseed (Brassica napus L.). To understand MES-induced male sterility in rapeseed better, comp...

Serotonin is a well-known agent that plays various roles in animals, and little known plants. In this study, the effect of exogenous serotonin was tested on Brassica napus L. (rapeseed) under salt stress. The results revealed application 200 µmol/L had best protection salinity. Exogenous effectively alleviated growth inhibition seedlings caused by salinity, significantly promoted accumulation f...

BACKGROUND Tocopherols are important antioxidants in vegetable oils; when present as vitamin E, tocopherols are an essential nutrient for humans and livestock. Rapeseed (Brassica napus L, AACC, 2 n = 38) is one of the most important oil crops and a major source of tocopherols. Although the tocopherol biosynthetic pathway has been well elucidated in the model photosynthetic organisms Arabidopsis...

Rapeseed (Brassica napus L.) is a nutritious vegetable, while cadmium (Cd) pollution threatens the growth, productivity, and food security of rapeseed. By studying effects iminodisuccinic acid (IDS), an easily biodegradable environmental friendly chelating agent, on Cd distribution at organ cellular level, we found IDS promoted dry matter accumulation rapeseed increased contents photosynthetic ...

Seed weight is a very important and complex trait in rapeseed (Brassica napus L.). The seed weight of rapeseed shows great variation in its natural germplasm resources; however, the morphological, cytological and genetic causes of this variation have remained unclear. In the present study, nine highly pure inbred rapeseed lines with large seed weight variation and different genetic backgrounds ...

Rapeseed (Brassica napus L.) is the most important oil crop of temperate climates. Rapeseed oil contains tocopherols, also known as vitamin E, which is an indispensable nutrient for humans and animals due to its antioxidant and radical scavenging abilities. Moreover, tocopherols are also important for the oxidative stability of vegetable oils. Therefore, seed oil with increased tocopherol conte...
