The composition of rice (Oryza sativa L.) grain fatty acids (18% palmitic acid, 36% oleic acid and 37% linoleic acid) is suboptimal for rice storage and utilisation of rice bran oil as food grade oil or a source of biodiesel. Genetic manipulation of fatty acid composition in rice bran oil to increase oleic acid levels at the expense of linoleic acid and palmitic acid would not only add extra value to the rice, but also enhance health benefits for consumers. Four putative rice microsomal Δ12-fatty acid desaturase (OsFAD2) genes were identified as potentially important target genes to achieve this improvement. Reverse transcription–PCR analysis indicated that OsFAD2–1 was the most highly expressed gene in rice grains. RNA interference (RNAi) suppression of the expression of OsFAD2–1 resulted in an increase of oleic acid and a reduction of linoleic and palmitic acids in T3 grains. The research here showed that in the rice grains, the OsFAD2–1 enzyme was an effective target for raising oleic acid levels at the expense of the oxidatively unstable linoleic acid and the cholesterol-raising palmitic acid.

Knowledge about the contents and type of fatty acids (FAs) in rice bran is beneficial, particularly from a nutritional and health standpoint. An experiment was conducted to assess the genetic variability and diversity for FA components in 215 rice landraces during kharif 2015 and kharif 2016 by following the RCB design with two replications. Palmitic (C16:0), oleic (C18:1) and linoleic (C18:2) were the major fatty acids ranging from 12.59% to 20.25%, 37.60% to 49.17% and 31.55% to 44.67%, respectively. Analysis of variance revealed significant differences in all the FA components except for linolenic acid. Results showed that environmental factors play a significant impact on the expression of FA contents. Fatty acid components showed intermediate to low genotypic and phenotypic coefficient of variation, intermediate to high heritability and low to moderate genetic advance as percent of the mean. Oleic acid content was negatively correlated with palmitic acid, stearic acid, and linoleic acid contents. Principal component analysis and cluster analysis discriminated the 215 rice landraces into five main groups with a major contribution of oleic acid, linoleic acid, and palmitic acid contents. Landraces Kadamphool, Ratanchudi and Bathrash possessed the highest amount of oleic acid/linoleic acid ratio. Information generated through this study will be functionally useful in developing rice varieties having high-quality bran oil.

Watermelon Seed

Seed oil percentage (SOP) and fatty acid composition of watermelon (Citrullus lanatus) seeds are important traits in Africa, the Middle East, and Asia where the seeds provide a significant source of nutrition and income. Oil yield from watermelon seed exceeds 50% (w/w) and is high in unsaturated fatty acids, a profile comparable to that of sunflower (Helianthus annuus) and soybean (Glycine max) oil. As a result of novel non-food uses of plant-derived oils, there is an increasing need for more sources of vegetable oil. To improve the nutritive value of watermelon seed and position watermelon as a potential oil crop, it is critical to understand the genetic factors associated with SOP and fatty acid composition. Although the fatty acid composition of watermelon seed is well documented, the underlying genetic basis has not yet been studied. Therefore, the current study aimed to elucidate the quality of watermelon seed oil and identify genomic regions and candidate genes associated with fatty acid composition. Seed from an F2 population developed from a cross between an egusi type (PI 560023), known for its high SOP, and Strain II (PI 279261) was phenotyped for palmitic acid (16:0), stearic acid (18:0), oleic acid (18:1), and linoleic acid (18:2). Significant (P < 0.05) correlations were found between palmitic and oleic acid (0.24), palmitic and linoleic acid (–0.37), stearic and linoleic acid (–0.21), and oleic and linoleic acid (–0.92). A total of eight quantitative trait loci (QTL) were associated with fatty acid composition with a QTL for oleic and linoleic acid colocalizing on chromosome (Chr) 6. Eighty genes involved in fatty biosynthesis including those modulating the ratio of saturated and unsaturated fatty acids were identified from the functionally annotated genes on the watermelon draft genome. Several fatty acid biosynthesis genes were found within and in close proximity to the QTL identified in this study. A gene (Cla013264) homolog to fatty acid elongase (FAE) was found within the 1.5-likelihood-odds (LOD) interval of the QTL for palmitic acid (R2 = 7.6%) on Chr 2, whereas Cla008157, a homolog to omega-3-fatty acid desaturase and Cla008263, a homolog to FAE, were identified within the 1.5-LOD interval of the QTL for palmitic acid (R2 = 24.7%) on Chr 3. In addition, the QTL for palmitic acid on Chr 3 was located ≈0.60 Mbp from Cla002633, a gene homolog to fatty acyl- [acyl carrier protein (ACP)] thioesterase B. A gene (Cla009335) homolog to ACP was found within the flanking markers of the QTL for oleic acid (R2 = 17.9%) and linoleic acid (R2 = 21.5%) on Chr 6, whereas Cla010780, a gene homolog to acyl-ACP desaturase was located within the QTL for stearic acid (R2 = 10.2%) on Chr 7. On Chr 8, another gene (Cla013862) homolog to acyl-ACP desaturase was found within the 1.5-LOD interval of the QTL for oleic acid (R2 = 13.5%). The genes identified in this study are possible candidates for the development of functional markers for application in marker-assisted selection for fatty acid composition in watermelon seed. To the best of our knowledge, this is the first study that aimed to elucidate genetic control of the fatty acid composition of watermelon seed.

Fatty Acid Profiling

Zanthoxylum plants, important aromatic plants, have attracted considerable attention in the food, pharmacological, and industrial fields because of their potential health benefits, and they are easily accessible because of the wild distribution in most parts of China. The chemical components vary with inter and intraspecific variations, ontogenic variations, and climate and soil conditions in compositions and contents. To classify the relationships between different Zanthoxylum species and to determine the key factors that influence geographical variations in the main components of the plant, the fatty acid composition and content of 72 pericarp samples from 12 cultivation regions were measured and evaluated. Four fatty acids, palmitic acid (21.33–125.03 mg/g), oleic acid (10.66–181.37 mg/g), linoleic acid (21.98–305.32 mg/g), and linolenic acid (0.06–218.84 mg/g), were the most common fatty acid components in the Zanthoxylum pericarps. Fatty acid profiling of Zanthoxylum pericarps was significantly affected by Zanthoxylum species and geographical variations. Stearic acid and oleic acid in pericarps were typical fatty acids that distinguished Zanthoxylum species based on the result of discriminant analysis (DA). Palmitic acid, palmitoleic acid, trans-13-oleic acid, and linoleic acid were important differential indicators in distinguishing given Zanthoxylum pericarps based on the result of orthogonal partial least squares discriminant analysis (OPLS-DA). In different Zanthoxylum species, the geographical influence on fatty acid variations was diverse. This study provides information on how to classify the Zanthoxylum species based on pericarp fatty acid compositions and determines the key fatty acids used to classify the Zanthoxylum species.

There are several underexploited plant seeds or fruits in Nigeria with little information about their chemical composition. To this end a comprehensive study on fatty acid, phospholipids and phytosterols composition of bitter melon (Momordica charaantia) fruit and ebony tree (Diospyros mespiliformis) fruit pulp were determined using standard analytical techniques. The most concentrated fatty acid (%) was linoleic acid in Momordica charantia fruit (45.47) and 44.82 in Diospyros mespiliformis fruit pulp. The increasing order of the concentrated fatty acids in Momordica charantia fruit were: linolenic acid (2.38) < stearic acid (7.52) < oleic acid (20.18) < palmitic acid (23.64) < linoleic acid (45.47) while that of Diospyros mespiliformis fruit pulp were: linolenic acid (5.73) < stearic acid (8.62) < oleic acid (18.95) < palmitic acid (20.88) < linoleic acid (44.82). Arachidonic, arachidic, palmitoleic, margaric, behenic, erucic, lignoceric, myristic, lauric, capric and caprylic acids were present in small quantities with none of them recording up to 1.0% in both of the two samples. The results also showed low concentration of monounsaturated fatty acids (MUFA) (20.41%) in Momordica charantia fruit and 19.13% in Diospyros mespiliformis fruit pulp, and values of polyunsaturated fatty acid (PUFA) were 2.44 and 5.78% for the two samples, respectively. The respective phospholipids composition showed a highest concentration of phosphatidylcholine in Momordica charantia and Diospyros mespiliformis (100.31and 88.12 mg/100 g) while lysophosphatidylcholine and phosphatidic acid were the least concentrate values of 12.62 and 14.52 mg/100 g in Momordicacharantia and Diospyros mespiliformis, respectively. The concentrations of phytosterols were of low values except in sitosterol with values of 153.28 and 119.46 mg/100 g in Momordica charantia and Diospyros mespiliformis, respectively. This study provides an informative lipid profile that will serve as a basis for further chemical investigations and nutritional evaluation of Momordica charantia fruit and Diospyros mespiliformis fruit pulp.

The effects of inclusion of different fatty acids in the medium on the rate of esterification of palmitic acid and its stereospecific distribution among the three positions of the triacyl-sn-glycerols by preparations of rat adipocytes in vitro have been determined. Myristic acid, stearic acid, oleic acid and linoleic acid were used as diluents and the concentration of the combined unesterified fatty acids in the medium was held constant; only the proportion of palmitic acid was varied. The amount of palmitic acid esterified was always linearly related to its relative concentration in the medium and was not significantly affected by the nature of the diluent fatty acid chosen. Constant relative proportions were recovered in triacylglycerols and in intermediates in each instance. The amount of palmitic acid esterified to each of the positions of the triacyl-sn-glycerols was linearly dependent on the relative proportion in the medium but the nature of the relationship was markedly influenced by which fatty acid was present. When stearic acid was present, simple relationships were found over the whole range tested. When either myristic acid, oleic acid or linoleic acid was present, abrupt changes in the manner of esterification of palmitic acid were observed in position sn-1 when the relative concentrations of palmitic acid and the diluent reached critical values, which differed with each fatty acid. In position sn-2 when oleic acid or linoleic acid was present, a similar change was observed, and in position sn-3 it was obtained with myristic acid as diluent. The results are discussed in terms of changes in the relative affinities of the acyltransferases for palmitic acid. Palmitic acid was esterified into various molecular species in proportions that indicated acylation with non-correlative specificity at higher relative concentrations but not at lower.

In the last decades many researches were made to change the animal product food’s composition. The production of better fat-compound milk and dairy products became a goal in the name of health conscious nutrition. These researches were motivated by the non adequate milk fat’s fatty acid composition. There have been made researches in order to modify the milk’s fatty acids’ composition to reach the expectations of functional foods. With the optimal supplement of the feed can be increased the proportion of the polyunsaturated fatty acids and can decreased the saturated fatty acids. Row fat content of milk was not decreasing in the course of examination neither of the cold extruded linseed nor the whole linseed supplement as opposed to observations experienced by other authors. In case of monounsaturated and polyunsaturated fatty acids when supplementing with cold extruded linseed the most significant change was observable in the concentration of the elaidic acid, oleic acid, linoleic acid, alfa-linolenic acid, conjugated linoleic acid. In case of saturated fatty acids the quantity of palmitic acid and myristic acid lowered considerably. When observating the feeding with whole linseed the concentration of many fatty acids from the milkfat of saturated fatty acids lowered (caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid). The quantity of some unsaturated fatty acids was showing a distinct rise after feeding with linseed, this way the oleic acid, alfa-linolenic acid, conjugated linoleic acid, eicosadienoic acid. The aim of the study was to produce food which meets the changed demands of customers as well. The producing of milk with favourable fatty acid content from human health point of view can give scope propagate the products of animal origin.
