枸杞成熟与干制过程中多糖积累的蛋白质组学 研究进展

随着后基因组时代的到来,蛋白质组学越来越广泛地应用到生命科学领域,目前主要应用于医学、生物学、植物学,近些年在食品科学方面也进行了相关研究。应用蛋白质组学在植物生长发育和成熟衰老方面的研究比较常见,但在加工环节中的应用并不多见。该方法能通过研究植物体相关蛋白质而在本质上动态地揭示植物从生长发育到成熟衰老过程的机制,为研究枸杞果实成熟及干制过程中多糖积累提供了新的思路和理论支撑。本文综述了枸杞果实成熟及干制过程中多糖积累的研究进展,简单介绍蛋白质组学、蛋白质组学的研究技术及其在植物及加工环节中的研究进展,并展望蛋白质组学技术在枸杞果实成熟及干制过程中多糖积累的研究前景,为今后蛋白质组学的应用与发展提供一定的参考和理论依据。     

THIOLS AND DISULPHIDES IN QUIESCENT AND GERMINATING BARLEY GRAINS,BOTH DORMANT AND MATURE

Reduced and oxidised glutathione, cysteine, cystine and traces (too small to quantify) of γ-glutamyl-cysteine and cysteinylglycine were detected, in about the same amounts, in extracts of the embryos of dormant and mature barleys. During micromalting the levels of the thiols and disulphides altered in various ways, but altered in the same ways in dormant and mature samples of grain until germination began. An early decline in the glutathione content of embryos was mirrored by a rise in the amount in degermed grains. Histochemical tests and analyses of isolated tissues showed that in the quiescent grains thiols were concentrated in the embryo (particularly the scutellum) and in the aleurone layer and isolated embryos released thiols into an incubation medium. We conclude that the endogenous thiols and disulphides are not obviously involved in the regulation of dormancy.     

A comparison of the lipid compositions of the lipoproteins of the intestinal and popliteal lymph and plasma of sheep

The lipids and lipoproteins of intestinal lymph in the sheep make a contribution to the corresponding fractions in plasma and thence affect lipid compositions in other tissues. As a first step towards assessing this contribution, the lipoproteins of intestinal lymph, peripheral (popliteal lymph) and plasma have been isolated for compositional studies. Popliteal lymph and the plasma were similar in the distributions of lipids among the major lipoprotein fractions with high-density lipoproteins accounting for just over half of the total lipid present. In intestinal lymph, 80 per cent of the total lipid was associated with the very low-density lipoprotein fraction. Whereas triacylglycerols comprised the principal lipid component of the very low-density lipoprotein and low-density lipoprotein fractions of the intestinal lymph and were present in the high-density lipoprotein fraction, they were present in essence only in the very low-density lipoprotein fraction of popliteal lymph and plasma, where high concentrations of cholesteryl esters and phospholipids were found in all the lipoprotein fractions. The fatty acid compositions of each lipid class were also determined. The most distinctive feature of the results was the distribution of the essential fatty acid, linoleic acid, among the lipid components. In all lipid classes in each of the body fluids, the concentration of this component was highest in the high-density lipoproteins and lowest in the very low-density lipoproteins. Higher concentrations tended to be present in the triacylglycerols and phosphatidylcholine fractions of intestinal lymph than of plasma and popliteal lymph, but the opposite was true of the cholesteryl esters. The results are discussed in terms of the sources of the linoleic acid in the lipids of intestinal lymph of ruminant animals.     

Accumulation and distribution of cadmium and lead in wheat (Triticum aestivum L.) grown in contaminated soils from the oasis, north-west China

BACKGROUND: Crops grown in soils contaminated by heavy metals are an important avenue for toxic metals entering the human food chain. The objectives of our study were to investigate the accumulation and distribution of cadmium (Cd) and lead (Pb) in wheat plants cultivated in arid soils spiked with different doses of heavy metal, as well as bioavailability of these metals in the contaminated arid soils from the oasis, north‐west China. RESULTS: The concentrations of Cd in the roots of wheat plants were about 5, 14 and 8 times higher than those in the shoots, shells and grains, respectively. The concentrations of Pb in the roots were about 23, 76 and 683 times higher than those in the shoots, shells and grains, respectively. Grains contained 11–14% and 0.1–0.2% of Cd and Pb found in roots of wheat plants. The bioconcentration factor (BCF) is the ratio of metal concentration in plant tissues and metal concentration in their rooted soils. The average BCF of Cd and Pb in grains was 0.6270 and 0.0007. Cd and Pb contents in different parts of wheat plants mainly correlated with the bound‐to‐carbonate metal fractions in contaminated arid soils. CONCLUSION: The preliminary study indicated that Cd and Pb were predominantly accumulated and distributed in wheat roots and shoots, and only a small proportion of these metals can reach the grains. The carbonate fractions mainly contributed to Cd and Pb bioavailability in contaminated arid soils. Copyright © 2010 Society of Chemical Industry     

基于时空与风险物视角的茶叶风险分级模型的构建

研究利用2016-2020年全国茶叶监督抽检数据,分析茶叶产业链中关键环节的风险并进行分级排序,同时对数据进行时空分析。采用熵值法计算茶叶产业链中关键环节风险物大小,并利用二八原则,对风险进行分级排序;采用描述性统计方法对茶叶数据进行时空分析;利用全局与局部自相关分析方法探索茶叶中风险等级高以及较高风险物的全国空间分布规律。研究发现,茶叶风险物在不同环节风险级别不同：生产环节和流通环节高风险物质是氟、砷、铜、镉、铬和铅,餐饮环节高风险物质是氟、铅、联苯菊酯、多菌灵、啶虫脒和吡虫啉;2016-2020年,茶叶不合格率总体变化稳定,内蒙古茶叶不合格率最高,抽样环节中流通环节不合格率最高,抽样场所中生产环节茶叶不合格主要发生在成品库已检区、流通环节茶叶不合格主要发生在超市;全国各省茶叶中高及较高风险物合格率只有柠檬黄存在全局空间相关性,局部自相关分析时,只有氟、铅和草甘膦有高高集聚和低低集聚的现象。结合研究结果,对茶叶监管和企业自律的重点提出了建议。

Glucose,fructose and sucrose content in broccoli,white cabbage and Portuguese cabbage grown in early and late seasons

Consumption of Portuguese cabbage and white cabbage is very high in Portugal, but diets including broccoli have been highly recommended owing to recognition of the health‐protective effects of secondary plant metabolites. Broccoli production is generally concentrated in the summer/winter season, but the demand for a fresh product throughout the year requires production in other seasons. Sugars might affect flavour and the acceptance of broccoli by consumers. This study reports the free fructose, glucose and sucrose content in primary and secondary inflorescences of 11 cultivars of broccoli, one white cabbage and four Portuguese cabbages grown in early (March–July) and late (August–January) seasons in the northern region of Portugal. On average the results show that the total free sugar content in the broccoli cultivars, except for cv Marathon, is significantly (P < 0.05) lower than in the other cabbages. Fructose was the major sugar in the three types of Brassica, representing between 48.8 and 56.9% of the total sugar content in broccoli cvs Marathon and Senshi respectively and between 48.7% (cv Mirandela) and 53.8% (cv Murciana) in the other cabbages. Glucose was the second major sugar, while sucrose represented a maximum of 20.5% in broccoli cv Shogun and 11.1% in cv Murciana. The growing season influenced the free sugar content, with generally higher levels in the spring/summer than in the summer/winter season in broccoli, while an opposite tendency was noted in the other Brassica species. In broccoli the sugar levels in the primary inflorescences were generally lower than in the secondary inflorescences, except for sucrose. © 2001 Society of Chemical Industry
