Abstract
Camelina sativa (L.) Crantz is an oilseed plant common in Europe and Asia. This study used the gas chromatography-mass spectrometry (GC-MS) to examine the differences in the aroma on the basis of extraction method such as water distillation extraction (CSPW), Solid-phase microextraction (CSPM) and subcritical extraction (CSPS). Antibacterial test was evaluated by the microdilution method against Salmonella typhimurium, Streptococcus pneumoniae, Escherichia coli, Strepococcus pyogenens, Staphylococcus aureus, and antioxidant activity was determined through DPPH free radical, hydroxyl free radical, and superoxide anion radical scavenging capacity activity. The result revealed that three extraction methods were distinct from each other based on their volatile compounds. Sixty-one volatiles of diverse chemical nature were identified and quantified. The volatile components contain thioether, aldehydes, alcohols, ketones, acids, esters, alkene, alkanes, amide, and furan compounds. The volatile components of Camelina sativa (L.) Crantz have good antibacterial and antioxidant activities. Furthermore, this work provides reference methods for detecting novel volatile organic compounds in plants and products.

Abstract
Sprouts are increasingly present in the human diet, being tasty and healthy foods high in antioxidant compounds. Although there is a body of literature on the sprouting of many plant species, Camelina sativa (L.) Crantz has not yet been studied for this purpose. This study aimed to characterize the main bioactive compounds and antioxidant potential of seeds and sprouts of five different Camelina cultivars (ALBA, CO46, CCE43, JOELLE, and VERA). In particular, the contents of phenolic compounds (PCs), phenolic acids (PAs), and glucosinolates (GLSs) were investigated. PCs, PAs, GLSs, and the antioxidant activity of seeds differed among cultivars and were greatly increased by sprouting. A PCA analysis underlined both the effect of the cultivar (PC2) and the germination (PC1) on the nutritional properties of Camelina. The best nutritional properties of seeds were observed for ALBA and CCE43, while the best nutritional properties of sprouts were recorded for CCE43 and JOELLE, since the latter cultivar showed a greater enhancement in phytochemical content and antioxidant activity with sprouting. Finally, a UHPLC-UV procedure for the analysis of GLSs in Camelina was developed and validated. The performance criteria of the proposed method demonstrated that it is useful for the analysis of GLSs in Camelina.

Genome-Wide Identification and Expression Analysis of Fatty Acid Desaturase ( FAD) Genes in Camelina sativa (L.) Crantz. Int J Mol Sci 2022; 23:ijms232314550.

Abstract
Camelina sativa (L.) Crantz is an indispensable oilseed crop, and its seeds contain many unsaturated fatty acids. FAD (fatty acid desaturase) regulates the synthesis of unsaturated fatty acids. In this research, we performed CsFAD gene family analysis and identified 24 CsFAD genes in Camelina, which were unevenly distributed on 14 of the 19 total chromosomes. Phylogenetic analysis showed that CsFAD includes four subfamilies, supported by the conserved structures and motifs of CsFAD genes. In addition, we investigated the expression patterns of the FAD family in the different tissues of Camelina. We found that CsFAD family genes were all expressed in the stem, and CsFAD2-2 was highly expressed in the early stage of seed development. Moreover, during low temperature (4 °C) stress, we identified that the expression level of CsFAD2-2 significantly changed. By observing the transient expression of CsFAD2-2 in Arabidopsis protoplasts, we found that CsFAD2-2 was located on the nucleus. Through the detection and analysis of fatty acids, we prove that CsFAD2-2 is involved in the synthesis of linolenic acid (C18:3). In conclusion, we identified CsFAD2-2 through the phylogenetic analysis of the CsFAD gene family and further determined the fatty acid content to find that CsFAD2-2 is involved in fatty acid synthesis in Camelina.

Abstract
Diacylglycerol acyltransferases (DGAT) catalyze the final committed step of de novo biosynthesis of triacylglycerol (TAG) in plant seeds. This study was to functionally characterize DGAT3 genes in Camelina sativa, an important oil crops accumulating high levels of unsaturated fatty acids (UFAs) in seeds. Three camelina DGAT3 genes (CsDGAT3-1, CsDGAT3-2 and CsDGAT3-3) were identified, and the encoded proteins were predicted to be cytosolic-soluble proteins present as a homodimer containing the 2Fe-2S domain. They had divergent expression patterns in various tissues, suggesting that they may function in tissue-specific manner with CsDGAT3-1 in roots, CsDGAT3-2 in flowers and young seedlings, and CsDGAT3-3 in developing seeds. Functional complementation assay in yeast demonstrated that CsDGAT3-3 restored TAG synthesis. TAG content and UFAs, particularly eicosenoic acid (EA, 20:1n-9) were largely increased by adding exogenous UFAs in the yeast medium. Further heterogeneously transient expression in N. benthamiana leaves and seed-specific expression in tobacco seeds indicated that CsDGAT3-3 significantly enhanced oil and UFA accumulation with much higher level of EA. Overall, CsDGAT3-3 exhibited a strong abilty catalyzing TAG synthesis and high substrate preference for UFAs, especially for 20:1n-9. The present data provide new insights for further understanding oil biosynthesis mechanism in camelina seeds, indicating that CsDGAT3-3 may have practical applications for increasing both oil yield and quality.

Abstract
The present article discusses the results of the study of the pharmacological activity of plant extracts from Camelina sativa (L.) Crantz: total herb extract (ECS) and oil from seeds (OCS). ECS was obtained from non-fat raw materials by the method of fractional maceration with 70% ethanol. OCS was obtained by means of extraction in a Soxhlet apparatus. Possible hypoglycemic activity of the extracts and dose selection were evaluated by primary pharmacological screening. Maximum hypoglycemic activity for ECS and OCS at a dose of 200 mg/kg was detected. A deeper study of the hypoglycemic and hypolipidemic properties of the extracts was performed on an experimental model of metabolic syndrome in rats that was induced by excessive doses of fructose (20% solution) for 8 weeks. In the last 2 weeks, the animals additionally received extracts and the reference preparation Metformin® (150 mg/kg). The characteristics of glucose homeo-stasis were evaluated by oral glucose tolerance test and short insulin test. The study also examined the content of total cholesterol and triglycerides. It was found that ECS and OCS of Camelina sativa (L.) Crantz at a dose of 200 mg/kg being administered for 14 days under conditions of high-fructose diet statistically significantly inhibited the formation of glucose tolerance and insulin resistance. ECS was found to have a pronounced lipid-lowering effect on lipid metabolism. The obtained results require further study of this plant raw material.

Abstract
Camelina sativa (L.) Crantz is an important Brassicaceae oil crop with a number of excellent agronomic traits including low water and fertilizer input, strong adaptation and resistance. Furthermore, its short life cycle and easy genetic transformation, combined with available data of genome and other "-omics" have enabled camelina as a model oil plant to study lipid metabolism regulation and genetic improvement. Particularly, camelina is capable of rapid metabolic engineering to synthesize and accumulate high levels of unusual fatty acids and modified oils in seeds, which are more stable and environmentally friendly. Such engineered camelina oils have been increasingly used as the super resource for edible oil, health-promoting food and medicine, biofuel oil and high-valued chemical production. In this review, we mainly highlight the latest advance in metabolic engineering towards the predictive manipulation of metabolism for commercial production of desirable bio-based products using camelina as an ideal platform. Moreover, we deeply analysis camelina seed metabolic engineering strategy and its promising achievements by describing the metabolic assembly of biosynthesis pathways for acetyl glycerides, hydroxylated fatty acids, medium-chain fatty acids, ω-3 long-chain polyunsaturated fatty acids, palmitoleic acid (ω-7) and other high-value oils. Future prospects are discussed, with a focus on the cutting-edge techniques in camelina such as genome editing application, fine directed manipulation of metabolism and future outlook for camelina industry development.
