3-Butenyl-, 4-pentenyl-, 2-hydroxy-3-butenyl- and 4-hydroxy-3-indolylmethylglucosinolate were found to be major glucosinolates in developing pod tissue and seed of both high and low glucosinolate lines of rapeseed. These glucosinolate profiles along with decreases in the glucosinolate content of pod tissue over a period of 18 d after pollination, and increases in the seed, were consistent with the pod tissue being a source of glucosinolate accumulating in the seed.Key words: Rapeseed, Brassica napus L., Cruciferae, glucosinolate, seed development

Ad Libitum

Five swine experiments were conducted to evaluate rapeseed meal (RSM) of low glucosinolate content (Brassica napus L. cv. Bronowski). Two experiments involved 0, 25, 50, 75 and 100% substitution of either Bronowski meal or regular (B. campestris) meal for soybean meal or fishmeal used in the control diet. One experiment compared ad libitum-fed and partially restricted pigs. Another experiment involved digestibility studies, and the final one involved methionine and lysine supplementation. As the dietary levels of either Bronowski or regular RSM increased in the ration, protein digestion coefficients decreased from 79 and 80% to 76 and 78%, respectively, and energy coefficients decreased from 82% to 79 and 78%, respectively. The protein and energy digestibility coefficients for Bronowski RSM were estimated to be 68 and 59%; for regular RSM, 65 and 54%. With barley–wheat–RSM diets, pigs responded to 0.1% methionine, but not to lysine (P > 0.05). Pigs fed ad libitum consumed more Bronowski than regular RSM diet and performed as well as pigs fed soybean meal diets.

Abstract Production of vegetable oils is a vital agricultural resource and oilseed rape (Brassica napus) is the third most important oil crop globally. Although the regulation of lipid biosynthesis in oilseeds is still not fully defined, the acyl-CoA-binding proteins (ACBPs) have been reported to be involved in such metabolism, including oil accumulation, in several plant species. In this study, progressive changes in gene expression in embryos and seed coats at different stages of seed development were comprehensively investigated by transcriptomic analyses in B. napus, revealing dynamic changes in the expression of genes involved in lipid biosynthesis. We show that genes encoding BnACBP proteins show distinct changes in expression at different developmental stages of seed development and show markedly different expression between embryos and seed coats. Both isoforms of the ankyrin-repeat BnACBP2 increased during the oil accumulation period of embryo development. By contrast, the expression of the three most abundant isoforms of the small molecular mass BnACBP6 in embryos showed progressive reduction, despite having the highest overall expression level. In seed coats, BnACBP3, BnACBP4 and BnACBP5 expression remained constant during development, whereas the two major isoforms of BnACBP6 increased, contrasting with the data from embryos. We conclude that genes related to fatty acid and triacylglycerol biosynthesis showing dynamic expression changes may regulate the lipid distribution in embryos and seed coats of B. napus and that BnACBP2 and BnACBP6 are potentially important for oil accumulation.

The content of aliphatic, aromatic and indole glucosinolates were measured in the roots, hypocotyl, cotyledons and leaves of the high glucosinolate Brassica napus cultivar Midas over the first 10–14 d after seeding. For seedlings grown in light from emergence, glucosinolate content declined slightly then increased. Increase in the indole glucosinolate content of the shoot (hypocotyl and cotyledons) was caused by an increase in 3-indolylmethyl glucosinolate. When seedlings were confined to darkness for either 6 or 10 d after seeding, 3-indolylmethyl glucosinolate did not increase. The content of 4-hydroxy-3-indolylmethyl the dominant glucosinolate in the seed, declined in both light and dark grown seedlings. The individual glucosinolates in different parts of the seedling appeared to vary independently and to be related to development of specific organs or tissues. The complexity and relative rapidity with which amounts of the individual glucosinolates changed suggests the existence of an intricate metabolic control.Key words: Rapeseed, Brassica napus L., Cruciferae, glucosinolate, seedling development
