Integration of omics approaches to understand oil/protein content during seed development in Oilseed Crops
Plant Cell Reports, 2017Co-Authors: Manju Gupta, Shreedharan Sriram, Pudota B Bhaskar, Po Hao WangAbstract:Oilseed Crops, especially soybean (Glycine max) and canola/rapeseed (Brassica napus), produce seeds that are rich in both proteins and oils and that are major sources of energy and nutrition worldwide. Most of the nutritional content in the seed is accumulated in the embryo during the seed filling stages of seed development. Understanding the metabolic pathways that are active during seed filling and how they are regulated are essential prerequisites to crop improvement. In this review, we summarize various omics studies of soybean and canola/rapeseed during seed filling, with emphasis on oil and protein traits, to gain a systems-level understanding of seed development. Currently, most (80–85%) of the soybean and rapeseed reference genomes have been sequenced (950 and 850 megabases, respectively). Parallel to these efforts, extensive omics datasets from different seed filling stages have become available. Transcriptome and proteome studies have detected preponderance of starch metabolism and glycolysis enzymes to be the possible cause of higher oil in B. napus compared to other Crops. Small RNAome studies performed during the seed filling stages have revealed miRNA-mediated regulation of transcription factors, with the suggestion that this interaction could be responsible for transitioning the seeds from embryogenesis to maturation. In addition, progress made in dissecting the regulation of de novo fatty acid synthesis and protein storage pathways is described. Advances in high-throughput omics and comprehensive tissue-specific analyses make this an exciting time to attempt knowledge-driven investigation of complex regulatory pathways.

adaptation of Oilseed Crops across saskatchewan
Canadian Journal of Plant Science, 2010Co-Authors: W E May, Yantai Gan, S.a. Brandt, Hadley R Kutcher, C B Holzapfel, G P LafondAbstract:Differences in response to nitrogen (N) fertilizer will affect the production economics of field Crops. Currently, there is limited information comparing the agronomic and economic performance of juncea canola (Brassica juncea L.) and sunflower (Helianthus annuus L.) to napus canola (Brassica napus L.) and flax (Linum ustitatissimum L.) in Saskatchewan under no-till practices. A study of these species was carried out at five Saskatchewan locations over 3 yr and included eight nitrogen rates. All four species had a curvilinear increase in grain yield as N rate increased with the largest yield response observed in napus canola to as much as 200 kg N ha-1. The majority of the increase in flax grain yield occurred as the N rate increased from 10 to 90 kg ha-1, while most of the increase in grain yield of juncea canola and sunflower occurred as N increased from 10 to 70 kg ha-1. Biplot analysis indicated that grain yield variation was reduced at and above 50 kg N ha-1 in flax, napus canola and juncea canola, b...

water use and distribution profile under pulse and Oilseed Crops in semiarid northern high latitude areas
Agricultural Water Management, 2009Co-Authors: Yantai Gan, C A Campbell, L P Liu, P Basnyat, C L McdonaldAbstract:Abstract Oilseed and pulse Crops have been increasingly used to replace conventional summer fallow and diversify cropping systems in northern high latitude areas. The knowledge of water use (WU) and its distribution profile in the soil is essential for optimizing cropping systems aimed at improving water use efficiency (WUE). This study characterized water use and distribution profile for pulse and Oilseed Crops compared to spring wheat (Triticum aestivum L.) in a semiarid environment. Three Oilseeds [canola (Brassica napus L.), mustard (Brassica juncea L.) and flax (Linum usitatissimum L.)], three pulses [chickpea (Cicer arietinum L.), dry pea (Pisum sativum L.) and lentil (Lens culinaris Medik.)], and spring wheat were seeded in removable 100 cm deep × 15 cm diameter lysimeters placed in an Aridic Haploboroll soil, in southwest Saskatchewan in 2006 and 2007. Crops were studied under rainfed and irrigated conditions where lysimeters were removed and sampled for plant biomass and WU at various soil depths. Wheat yields were greater than pulse crop yields which were greater than Oilseed yields, and WUE averaged 4.08 kg ha−1 mm−1 for pulse Crops, 3.64 kg ha−1 mm−1 for Oilseeds, and ranged between 5.5 and 7.0 kg ha−1 mm−1 for wheat. Wheat used water faster than pulse and Oilseed Crops with crop growth. Pulse Crops extracted water mostly from the upper 60 cm soil depths, and left more water unused in the profile at maturity compared to Oilseeds or wheat. Among the three pulses, lentil used the least amount of water and appeared to have a shallower rooting depth than chickpea and dry pea. Soil WU and distribution profile under canola and mustard were generally similar; both using more water than flax. Differences in WU and distribution profile were similar for Crops grown under rainfall and irrigation conditions. A deep rooting crop grown after pulses may receive more benefits from water conservation in the soil profile than when grown after Oilseed or wheat. Alternating pulse Crops with Oilseeds or wheat in a well-planned crop sequence may improve WUE for the entire cropping systems in semiarid environments.

yield seed quality and sulfur uptake of brassica Oilseed Crops in response to sulfur fertilization
Agronomy Journal, 2007Co-Authors: S S Malhi, Yantai Gan, J P RaneyAbstract:Field experiments were conducted in 2003, 2004, and 2005 on a S-deficient Gray Luvisol (Boralf) soil near Star City, in northeastern Saskatchewan, to determine yield, seed quality and S uptake response of different Brassica (B.) Oilseed species/cultivars to S deficiency and S fertilization. A total of 20 treatments were tested in a factorial combination of four Oilseed Crops (B. juncea canola cv. Arid, B. juncea canola cv. Amulet, B. juncea mustard cv. Cutlass, and B. napus cv. In Vigor 2663 hybrid canola) and five rates of potassium sulfate fertilizer (0, 10, 20, 30, and 40 kg S ha -1 ). All B. species/cultivars responded positively for seed yield and most other parameters to S fertilizer in all 3 yr, but the magnitude of response varied with species/ cultivar and year. Seed yield was highest with Cutlass juncea mustard in a dry year (2003), but was highest with In Vigor 2663 hybrid canola in years with above-average precipitation (2004 and 2005). Seed yield was usually maximized at the rate of 30 kg S ha -1 for all B. species/ cultivars. Oil concentration in seed increased with S fertilization for all B. species/cultivars. There was a significant (albeit small) increase of protein concentration in seed due to S fertilization. Cutlass juncea mustard accumulated considerably high concentrations of glucosinolates in seed, but glucosinolate concentrations were low in other B. species/cultivars. Sulfur uptake in seed was highest with Cutlass juncea mustard in all years. The effects of S deficiency and applied S were more pronounced on seed than straw. In conclusion, S fertilizer requirements for optimum seed yield were similar for all the B. species/ cultivars used in this study on S-deficient soil, but higher yielding types of B. would produce greater seed yield by using S more efficiently.
