Abstract : An alkaloid-poor line of Washington lupin (Lupinus polyphyllus Lindl var SF/TA) was developed in an experiment started in 1982. The nutritive quality (alkaloid content, protein and amino acids, fat and fatty acids. macro- and micronutrients, fibre, sugars) yields, and seed quality of this line were studied. The results show that the total alkaloid content was low and varied in different seeds from 226 μg g?1 to 366 μg g?1 of dry matter. The main alkaloid was lupanine, but 16 other alkaloids (including sparteine and gramine) were also present. The var SF/TA cannot yet be used for human nutrition without processing although it would be a valuable protein crop. The results confirm that seeds which look different also vary in chemical composition. 相似文献

In Vitro Determination of the Antifungal Activity of Artemisia campestris Essential Oil from Algeria
Abderrahmane Houicher Hind Hechachna Fatih Özogul 《International Journal of Food Properties》2016,19(8):1749-1756
The chemical composition of the essential oil isolated from the aerial parts of Artemisia campestris from Algeria and its antifungal activity against 10 filamentous fungal strains were investigated. The A. campestris essential oil was obtained in a yield of 0.71% (v/w). The major constituents of the oil were α-pinene (18.65%), β-pinene (16.78%), β-myrcene (17.34%), and germacrene D (10.34%). Our study showed that A. campestris essential oil was a potent antifungal agent against some pathogenic fungal species. Fusarium graminearum was the most sensitive strain to A. campestris essential oil with minimal inhibitory concentration and minimal fungicidal concentration values of 1.25 µL/mL (v/v). The essential oil also exhibited a strong fungicidal activity against the tested fungi, except for Penicillium citrinum, P. viridicatum, and Aspergillus niger (MFC >20 µL/mL). Our findings suggested the application of A. campestris essential oil as a biofungicide in order to reduce the dependence on synthetic fungicides and ensure food safety and quality. 相似文献

BACKGROUND: Glutamine synthetase (GS; EC 6.3.1.2) is a key enzyme of nitrogen (N) assimilation, catalysing the synthesis of glutamine from ammonium and glutamate. Plants have two types of GS isoenzyme that are localised in different compartments: one in the cytosol (GS1) and the other in the chloroplast (GS2). GS1 is the major form of GS in plant roots and directly converts ammonium taken up by plant roots to glutamine. RESULTS: The GS1 gene cDNA of non‐heading Chinese cabbage (Brassica campestrisssp. chinensis Makino) cultivar ‘Suzhouqing’ was isolated by RT‐PCR (real‐time polymerase chain reaction) and (5′/3′)‐RACE (rapid amplification of cDNA ends) techniques. It was classified as GS1 by sequence alignment and motif search and named B. campestris ssp. chinensis Makino GS1 (BcGS1). Subcellular localisation analysis showed that BcGS1 was distributed in the cytoplasm of cells. BcGS1 was expressed in all parts, but mainly in the roots, which was verified by northern blotting analysis. Additionally, its expression was influenced by the N source concentration. CONCLUSION: These results suggest that BcGS1 is a novel member of the GS family in plants. BcGS1 was significantly related to N assimilation in non‐heading Chinese cabbage, demonstrating that this gene plays an important role in plant growth and development.

A phytotoxin from Xanthomonas campestris pv. retroflexus was isolated using a chromatographer and HPLC, and the components were identified to be a mixture of minor molecular compounds including organic acids and cyclo-(proline-phenylalanine). The greenhouse cultivation test was used to determine the influence of the isolated fractions on the growth of target weed redroot pigweed (Amaranthus retroflexus L). The experimental results demonstrated that the cyclo-(Pro-Phe) had the weed inhibit activity obviously on dicotyledonous weed and the mixture with six organic acids showed stronger bioactivity. Further, greenhouse and field test were processed, and the test showed that the use of the toxin appeared to have the potential to be developed further as a bioherbicide system to control weedy grasses. 相似文献

2S albumins were isolated from seeds of Andean lupin (Lupinus mutabilis Sweet) by buffer extraction, ammonium sulphate precipitation and ultrafiltration followed ion-exchange and reversed-phase
HPLC. The 2S albumin preparation (LM2S) contained eight albumins. The complete amino acid sequences of small and large subunits
of three major albumins (LM2S-4, -5 and -6) were determined by automated Edman degradation of S-pyridylethylated polypeptides and peptides obtained from them by enzymatic digestions. The small subunit of the dominant
2S albumin (LM2S-4) contains 39 amino acid residues and has a molecular mass of 4731 Da. The large subunit of LM2S-4 contains
74 amino acid residues (molecular mass=8708 Da). Two 2S albumin isoforms (LM2S-4 and -6) are due to the expression of two
distinct genes; LM2S-6 isoform has eight amino acid replacements when its sequence is compared with the sequence of LM2S-4.
The LM2S-5 isoform contains an identical small subunit to LM2S-4, and has in comparison with LM2S-4 two additional amino acid
residues at the N-terminus of the large subunit. The amino acid sequences of 2S isoforms from L. mutabilis showed high homology (78–83% identity) with 2S albumins from different Old World Lupinus species.
