Rapeseed breeding for oil content, quality, and sustainability.

Abstract: The successful development of 00-oilseed rape—also named canola (erucic acid free in seed oil and low glucosinolate content in the residual seed)—has opened almost unlimited avenues into the food and feed markets. Oilseed rape is today the world's third leading oil crop and contributes both to the economies and health of people around the world. During the last decades, the demand for vegetable oils as food, non-food, and biofuel has grown significantly. This demand could be satisfied due to improved agronomic developments, better processing methods, and improvements in the varieties available. The yield however varies in different countries, reflecting different input levels and production efficiency. This highlights the room for crop improvement, and the yield will continue to be the primary focus of many rapeseed improvement programs. Besides yield and yield stability increasing seed oil content and further improvement of oil and meal qualities have become one of the most important breeding criteria. Modern varieties are based on a relatively small subset of the available genetic diversities. Rapeseed is thus likely to respond strongly to programs aimed at selectively enhancing genetic variation for key economic input and output traits. This review outlines the progress and future challenges for rapeseed breeding.

Effect of pulsed electric field on functional and structural properties of canola protein by pretreating seeds to elevate oil yield

Abstract: Pulsed electric field (PEF) was applied to moisture-preconditioned canola seeds to evaluate the effect on oil yield The effect of PEF on functional and structural properties of canola protein left over after oil extraction were also examined in albumin and globulin fractions obtained at optimal conditions for oil yield Generally, PEF pretreatment significantly improved (P

Comparative proteome analysis of drought-sensitive and drought-tolerant rapeseed roots and their hybrid F1 line under drought stress.

Abstract: Rapeseed (Brassica napus L.), which is the third leading source of vegetable oil, is sensitive to drought stress during the early vegetative growth stage. To investigate the initial response of rapeseed to drought stress, changes in the protein expression profiles of drought-sensitive (RGS-003) and drought-tolerant lines (SLM-003), and their F1 hybrid, were analyzed using a proteomics approach. Seven-day-old rapeseed seedlings were treated with drought stress by restricting water for 7 days, and proteins were extracted from roots and separated by two-dimensional polyacrylamide gel electrophoresis. In the sensitive rapeseed line, 35 protein spots were differentially expressed under drought stress, and proteins related to metabolism, energy, disease/defense, and transport were decreased. In the tolerant line, 32 protein spots were differentially expressed under drought stress, and proteins involved in metabolism, disease/defense, and transport were increased, while energy-related proteins were decreased. Six protein spots in F1 hybrid were common among expressed proteins in the drought-sensitive and -tolerant lines. Notably, tubulin beta-2 and heat shock protein 70 were decreased in the drought-sensitive line and hybrid F1 plants, while jasmonate-inducible protein and 20S proteasome subunit PAF1 were increased in the F1 hybrids and drought-tolerant line. These results indicate that (1) V-type H+ ATPase, plasma-membrane associated cation-binding protein, HSP 90, and elongation factor EF-2 have a role in the drought tolerance of rapeseed; (2) The decreased levels of heat shock protein 70 and tubulin beta-2 in the drought-sensitive and hybrid F1 lines might explain the reduced growth of these lines in drought conditions.
