Cover crops can improve soil health by maintaining organic carbon (SOC) and nitrogen (N) contents, yet their dynamics in relation to crop yield a semi-arid cropping system are poorly understood. The main objective of this study was evaluate the response diverse winter cover species mixture on SOC N fractions relationship with sorghum (Sorghum bicolor L. Moench) wheat (Triticum aestivum L.)–sorg...

IDENTIFICATION OF A MARKET Developing a new market for an established international crop like canola (Brassica napus L., Brassica rapa L., Brassicaceae) requires significant care and study. Canola has been identified by several authors as a highly desirable food oil. Canola oils are relatively rich in monounsaturated fatty acids and with small percentages of both saturated and polyunsaturated f...

Winter oilseeds are cool season Brassica crops currently being grown in the upper Midwest and North-West of United States. They have potential to function as dual when rotation with corn, soybean, small grains. provide many benefits typical cover over winter, added benefit extra revenue growers who sell seeds for uses such biofuel, industrial products, human consumption, or animal feed. This re...

We studied the reuse of selenium (Se)-laden effluent for producing canola (Brassica napus) and subsequent bioproducts in central California. Canola was irrigated with poor quality waters [electrical conductivity (EC) of approximately 5 dS m(-1) sulfate-salinity, 5 mg B L(-1), and 0.25 mg Se L(-1)]. Typical seed yields were 2.2 metric tons ha(-1). Seeds were processed for their oil, and transest...

Brassica juncea (Indian mustard) has been identified as a potentially important crop for commercial production in low rainfall areas of Australia, as it has greater tolerance to heat and water stress than B. napus (canola). It is also more resistant to blackleg fungal disease and shattering. The success of B. juncea as a commercial crop will, to a large extent, depend upon its suitability for p...

The fungus Leptosphaeria maculans (L. maculans) is the causal agent of blackleg disease of canola/oilseed rape (Brassica napus) worldwide. We previously reported cloning of the B. napus blackleg resistance gene, LepR3, which encodes a receptor-like protein. LepR3 triggers localized cell death upon recognition of its cognate Avr protein, AvrLm1. Here, we exploited the Nicotiana benthamiana model...

Effects of salt stress on germination, seedling growth and activity of antioxidant enzymes in leaves of six cultivars of canola (Brassica napus L.) were investigated on two F1 hybrids (Hyola401, Hyola330) and four open pollinated cultivars (Zarfam, Okapi, RGs003 and Sarigol). Seeds were germinated under various levels of salinity (0, 50, 100, 150 and 200 mM NaCl solutions). An increase in NaCl ...

The growth of transgenic canola (Brassica napus) expressing a gene for the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase was compared to non-transformed canola exposed to flooding and elevated soil Ni concentration, in situ. In addition, the ability of the plant growth-promoting bacterium Pseudomonas putida UW4, which also expresses ACC deaminase, to facilitate the growth of non-tran...

The impact of genetically modified canola (Brassica napus) on biodiversity has been examined since its initial stage of commercialization. Various research groups have extensively investigated crossability and introgression among species of Brassicaceae. B. rapa and B. juncea are ranked first and second as the recipients of cross-pollination and introgression from B. napus, respectively. Crossa...
