The seeds from 18 Australian native plants were evaluated for their potential as food crops by assessing their nutritive values. Proximate analyses for water, protein and oil content were conducted, together with detailed analyses of the fatty acid content of the triglycerides, and of the amino acid content. Four plants, Hovea elliptica, Hardenbergia violacea, Crotalaria cunninghamii and Kennedia nigricans, were found to have a chemical composition which may have the potential for human food.

The Mediterranean region is one of the most water-scarce areas worldwide and is considered a climate-change hotspot. To assure the viability and competitiveness of irrigated agriculture, it is vital to implement strategies that can maximize water saving without compromising yield. Deficit irrigation (DI) for cultivating drought-tolerant species such as almond (Prunus dulcis (Mill.) D.A. Webb) can help in achieving this goal, while at the same time improving fruit chemical composition. This work evaluated the effect of DI techniques and cultivars on the chemical composition of almonds (cvs. Marta, Guara, and Lauranne) in order to elucidate the most suitable irrigation dose under water-scarcity scenarios. Three irrigation regimes were imposed: a control treatment (FI), which was fully irrigated, receiving 100% of the irrigation requirement (IR), and two sustained-deficit irrigation (SDI) strategies that received 75% (SDI75) and 65% (SDI65) of IR. Significant differences among cultivars and irrigation treatments were observed for antioxidant activity and organic acid, sugar, and fatty acid content, which were increased by the SDI strategies. In addition, highly significant correlations were found between leaf-water potential and components such as fumaric acid, sugars, and fatty acids. In terms of the cultivars, cv. Marta showed the highest antioxidant activity, cv. Guara was the richest in organic acids, and cv. Lauranne had the highest fatty acid content. Consequently, SDI strategies improved almond quality parameters related to their nutritional and sensory composition, with significant water savings (reductions of 25–35%) and without important yield loss.

Ocimum tenuiflorum L., commonly known as ruku in Malaysia, is usually cultivated as a garden ornamental plant because of its small purplish and some yellowish flower. Additionally, the young leaves of O. tenuiflorum L. are used to make Nasi Ulam. In this study, we investigated the nutritional values of O. tenuiflorum leaves and stems to find a rich source of essential nutrients needed in daily diet. High pressure liquid chromatography (HPLC) and gas chromatography/mass spectrophotometer (GC/MS) methods were used to measure the amino acid and fatty acid content of leaves and stems of O. tenuiflorum L. The result of antinutritional compositions of the leaves and stems displayed as a safe range of compounds that were effective to increase absorption of nutritional compound by body cells. The result of fatty acid profile showed that the butanoic acid as the highest amount of fatty acid content in stems and leave compared to other fatty acid compositions. The result of amino acids profile indicated that αaminobutyric acid and cysteine (non-essential amino acid) showed the highest and the lowest amount of amino acid content in stem and leaves consequently. Vitamin E and C showed the high and lowest amount of vitamins content in the leave and stem, respectively. In conclusion, the result of antinutritional and nutritional contents of O. tenuiflorum L. leaves and stems clearly indicated that the antinutritional compounds were in the safe range. The amount and nutritional content of the leaves and stem proved that this plant a good source to improve our body health system.

Aim: To evaluate the effects of radiation on oil and fatty acid content of cumin by irradiating seeds with varied doses of gamma rays viz.,100 Gy, 125 Gy, 150 Gy, 175 Gy. Study Design: Oil and fatty acid content was estimated by gas chromatography mass spectroscopy. Results: The result reveals that oil and fatty acid quantity were significantly changed upon radiation. Oil amount was increased in irradiated seeds whereas fatty acid content was decreased except petroselinic acid and linoleic acid which was increased in comparison to control. In contrast to non irradiated seeds, the lowest dose of gamma found beneficial as oil content and majority of fatty acids were increased. Conclusion: Therefore, irradiation of cumin seeds for protection and preservation purpose could significantly affect the fatty acid content of cumin as seeds are prone to fungal infections.

Abstract Background Oil and five main fatty acid content(especially linolenic acid content (LNA) )are six main quality traits in flax, and also the important target traits in flax breeding. However, the reports on genetic map construction and QTL mapping of linolenic acid content in flax are limited, which results in low accuracy and efficiency of quality breeding in oil flax. Construction the genetic linkage map and location the QTLs to discover the stable genetic QTLs sites related to oil content and fatty acid content, so as to provide targeted targets for breeders and improve breeding efficiency. Results In this study, a final integrated map consisting of 2,239 single nucleotide polymorphism (SNP) markers on 15 linkage groups (LGs) with an average distance of 0.46 cM between adjacent markers was generated using genotyping-by-sequencing (GBS) technique. A total of 21 quantitative trait loci (QTL)s for the six traits, i.e., palmitic acid content (PAL), stearic acid content (STE), oleic acid content (OLE), linoleic acid content (LIN), linolenic acid content (LNA), and oil content (OIL) in the RIL population under three environments. One QTL cluster harbored two QTLs for LIN and LNA trait, respectively was also identified. Especially, QTL qLIN-Group12-2 for LIN and QTL qLNA-Group12-2 for LNA on chromosome 12 were detected in multi-environments. Conclusions A high-density SNP genetic map with total 2239 markers was constructed with GBS technique, The total genetic distance of the SNP map was 1032.90 cM, with the average genetic distance of 0.46 cM per marker. A total of 21 quantitative trait loci (QTL)s for the six traits under three environments were determined. One QTL cluster harbored two QTLs for LIN and LNA trait, respectively was also identified. QTL qLIN-Group12-2 for LIN and QTL qLNA-Group12-2 for LNA on chromosome 12 were detected in multi-environments. These results provide more information for determining the seed quality related candidate genes and contribute to the marker-assisted selection in flax breeding.
