Oleic Acid Content

The study of the heritability of the oleic acid content in seed oil in recombinant inbred lines is the genetic basis for effective breeding work on the quality of sunflower oil. The experiments were carried out under field and laboratory conditions in VNIIMK, Krasnodar, Russian Federation in 2016-2020. We used 17 recombinant inbred sunflower lines of I4 and I5 generations obtained from crossing a medium-oleic LG27 line and a high-oleic LG26 line with subsequent self-pollination. The fatty acid composition of sunflower seed oil was analyzed using the method of gas-liquid chromatography of methyl esters on the Chromatek-Kristall 5000 device. Seventeen recombinant inbred sunflower lines in generation I4 showed a wide variation in the content of oleic acid in the oil of average seed samples from 39.00 % (RIL-1) to 92.24 % (RIL-42) and linoleic acid – from 43.28 to 1.35 %, respectively. In 2016, three lines were characterized 28 by an average oleic acid content of 55.64-65.54 %. Analysis of the fatty acid composition of oil in individual seeds of the next generation I5 of these lines confirmed, in general, their phenotypic ranks with a range of variability from 32.18 to 92.15 % in the content of oleic acid. The middle oleic lines RIL-21, RIL29 and RIL-30 also showed belonging to their phenotypic class in 2019 in the range of values from 59.80 to 63.14 %. The study of the conjugate variability of oleic acid values in the parent-progeny series in generations of I4–I5 revealed the presence of a significant strong positive correlation r = 0.97. At the same time, the coefficient of determination, defined as the square of the correlation coefficient which evaluates the degree of heritability of a trait, was 0.95, which indicates a significant influence of the genotype factor in general phenotypic variation.

AbstractHigh temperature enhances the oleic acid content in the oil of normal cultivars but conflicting results are reported on temperature effects on oleic acid content in HO cultivars: either no effect or an increase in oleic acid content with temperature. To investigate the effects of temperature on HO genotypes under natural field conditions, a three-year field trial was conducted using two sowing dates and three HO genotypes (two inbred lines and one hybrid). To compare our results with previous works, growing degree-days (GDD) were computed (base temperature=6°C). GDD accumulated during the “flowering – 25 days after flowering” period influenced fatty acid composition of seed. Oleic and linoleic acid contents were affected by accumulated GDD in two HO genotypes (one inbred line and the hybrid). There was an increase of about 3% in oleic acid content as response to more high GDD accumulated. Their content was not modified by GDD in the other inbred line. There was a genotype×environment interaction that we suppose depending on modifier genes. These genetic factors affected oleic acid content. This indicated the importance of breeding targeted to select hybrids with a stable oleic acid content and higher than 90%. Saturated fatty acids (palmitic and stearic) were also influenced by temperature, and there was genetic variability among genotypes.

Rapeseed (Brassica napus L.) with substantial lipid and oleic acid content is of great interest to rapeseed breeders. Overexpression of Glycine max transcription factors Dof4 and Dof11 increased lipid accumulation in Arabidopsis and microalgae, in addition to modifying the quantity of certain fatty acid components. Here, we report the involvement of GmDof4 and GmDof11 in regulating fatty acid composition in rapeseeds. Overexpression of GmDof4 and GmDof11 in rapeseed increased oleic acid content and reduced linoleic acid and linolenic acid. Both qPCR and the yeast one-hybrid assay indicated that GmDof4 activated the expression of FAB2 by directly binding to the cis-DNA element on its promoters, while GmDof11 directly inhibited the expression of FAD2. Thus, GmDof4 and GmDof11 might modify the oleic acid content in rapeseed by directly regulating the genes that are associated with fatty acid biosynthesis.

Pelleted Food

Conventional mice fed commercially prepared pelleted food, or a laboratory-prepared food consisting of casein, cornflour, bran, vitamins, and minerals, harboured a layer of lactobacilli on the nonsecretory epithelium of the stomach. In contrast, the majority of mice fed the laboratory-prepared diet to which corn, sunflower seed, or codliver oil had been added lacked a iactobacillus layer in the stomach. Analysis of the fatty acid content of the various diets, and feeding mice diets of known fatty acid composition, led to the conclusion that the relative amounts of palmitic and oleic acid in the food can influence the number of tissue-associated lactobacilli in the mouse stomach.

The purpose of this project is to modify the fatty acid composition in soybean seeds to improve soybean oil quality and functionality. By sequencing the FAD2-1A and FAD2-1B genes in 24 plant introductions, we identified two novel mutant alleles: one for each gene that is responsible for the elevated oleic acid content in four plant introductions. The combination of the newly identified mutant FAD2-1B allele with existing or the novel mutant FAD2-1A alleles created soybean lines with more than 80% oleic acid content. Combination of two mutant FAD2-1A and FAD2-1B with mutant FAD3A or mutant FAD3C or both resulted in high oleic acid content of 80 - 85% and linolenic acid content in the range from 1.5 - 4%. Perfect molecular markers associated with these mutant alleles were designed to help select the soybean lines with genotypes of interest in early generations in breeding. The high oleic acid and high oleic acid low linolenic soybeans produced have an improved stability across growing environments compared to existing sources.
