After cereals, oilseeds are the second-largest food reserves in the world. According to available statistics, more than 95 percent of Iran's oil needs are imported. Given the growing need for edible oils in Iran, it is important to identify fatty acids in the oilseed crops. Camelina sativa L. is an oil-medicinal plant and belongs to the Brassicaceae family that requires very little water and fertilizers. It is known as a low input plant. In this study, to analyze the fatty acid profile for breeding programs and specific industries, 137 doubled haploid camelina lines were evaluated in terms of fatty acid composition and variability of fatty acids trait, to estimate phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability, and expected genetic advance. The determination of fatty acid by gas chromatography showed that 18 types of fatty acids were detectable in camelina seed oil. It is shown that the two fatty acids (C14:0 and C16:1) have the highest PCV and GCV. The highest heritability for C20:2, C20:3 and C20:0 fatty acids was estimated 98.92, 98.59 and 96.49 percent, respectively. In this study, two lines with linoleic acid of 35.81-36.67% and four lines with values ranged from 22.08-23.00% were introduced. The ratio of omega-6 to omega-3 (0.479-0.759) was obtained in the studied lines.

Ferulago angulata (Schlecht) Boiss is one of the valuable and endemic medicinal plants of Iran, which is of great importance due to the source of terpenoid compounds and antimicrobial properties. In current study, the effects of different concentrations of salicylic acid and yeast extract in cell suspension culture of F.angulata on expression pattern of the HMGR and GPPS genes (involved in terpenes biosynthesis) were investigated for the first time. The F. angulata cell suspension cultures were initiated and established using calli derived from leaf explants, and salicylic acid and yeast extract elicitors (with 50, 100 and 150 mg/L concentrations) were added to the cultures during active growth. Then, the cell samples were prepared at 24, 48 and 72 hours after treatment. Analysis of expression pattern of HMGR and GPPS genes using Real-time PCR showed that the expression of both genes were significantly influenced by the type and concentration of the elicitors and also the times after treatment. The relative expression of HMGR and GPPS genes under elicitors were increased compared to the control, and furthermore, the increase in the relative expression of these genes under salicylic acid treatment was significantly higher than that of yeast extract treatment. The highest relative expression of GPPS and HMGR genes was related to 100 mg/L salicylic acid treatment at 24 hours after treatment. However, the highest relative expression of these genes was observed under the 24 and 72 hours after treatment of 150 mg/L yeast extract. The results of this study could be useful in metabolic engineering of F. angulata.
