Blackleg disease, caused by the fungal pathogen Leptosphaeria maculans, is most devastating disease of canola (Brassica napus, oilseed rape) worldwide. Breeding for genetic resistance widely used tool controlling this and minimizing impact on yield. To date, five genes (Rlm2, LepR3, Rlm4, Rlm7, Rlm9) have been cloned from B. representing alleles two different gene loci, Rlm2-LepR3 Rlm4-7-9. We ...

In Brassica , the thioredoxin h proteins, THL1 and THL2, were previously found to be potential inhibitors of the S receptor kinase (SRK) in the Brassica self-incompatibility response. To investigate the biological roles of THL1 and THL2 in pollen-pistil interactions, the stigma-specific SLR1 promoter was used to drive antisense THL1/2 expression in Brassica napus cv. Westar. This cultivar is no...

Millipedes are known by their importance in ecological systems, although some species regarded as agricultural pests poly- or monocultures. Canola (Brassicaceae: Brassica spp.) is an important feedstock for biodiesel production and a potential ingredient the food industry, but with several arthropod causing damage to its cultivation. In this perspective, study reports still unknown relation of ...

Pest management practices may be contributing to a decline in wild bee populations in or near canola (Brassica napus L.) agroecosystems. The objective of this study was to investigate the direct contact toxicity of five technical grade insecticides--imidacloprid, clothianidin, deltamethrin, spinosad, and novaluron--currently used, or with potential for use in canola integrated pest management o...

Cropping sequences integrating perennial forages and annual crops can generate multidimensional agroeconomic environmental benefits. A 4-yr cropping sequence study was conducted from 2013 to 2016 evaluate the relative merits of various sequences. Three forage seed (creeping red fescue [Festuca rubra L.], alsike clover [Trifolium hybridum pratense L.]) four food (wheat [Triticum aestivum canola ...

In the Botanical Garden and Research Laboratory of Institute Pure Applied Biology, Bahauddin Zakariya University, Multan (Pakistan) current work was performed to examine effect foliar spray potassium for lessening toxicity heavy metal in three varieties Canola (Brassica napus L.) viz; Exceed, Cyclone Legend. Seeds were grown pots. They arranged a Completely Randomized Design (CRD). When seeds g...

Introduction In 2014, the top five genetically modified (GM) or transgenic crop producers were the United States, Brazil, Argentina, India, and Canada, together accounting for 90% of the global area of these crops (James, 2015). The United States has 40% of the area; Brazil, 23%; Argentina, 13%; India, 6%; and Canada, 6%. Although GM cultivars of 11 crops have been released, 4 crops cover 99% o...

Canola (Brassica napus L. and B. rapa L.), is one of the major oilseed crops grown worldwide. With significant expansion of acreage sown to canola during the past two decades, concern about blackleg, the most serious disease of canola, has increased (3,4). Blackleg disease is caused by Leptosphaeria maculans (Desmaz.) Ces. & De Not. (anamorph: Phoma lingam (Tode:Fr.) Desmaz.). The pathogen can ...
