This book was released on 2016 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two soybean omega-6 fatty acid desaturase genes [FAD2-1A and FAD2- 1B] are responsible for converting oleic acid into linoleic acid (Okuley et al., 1994). Plant introductions [PI] 603452 and 283327 have naturally occurring mutations in FAD2-1A and FAD2-1B, respectively, which hinder the conversion of oleic acid to polyunsaturated fatty acids. The end result is more functional soybean oil with exceptionally high levels of oleic acid. The homozygous alleles of FAD2-1A and FAD2-1B were combined in a BC3F2:4 [backcross three, second filial generation selected, advanced to the fourth filial generation] population of forty-eight lines and were evaluated in Tennessee. Each line belonged to a double homozygous genotypic class: i) double wild-type [WT] (AABB), ii) mutant FAD2-1A with WT FAD2-1B (aaBB), iii) the converse (AAbb), and iv) double mutant (aabb). All genotypic groups yielded similarly to each other and to three high yielding checks (p

This book was released on 2013 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybeans with seed oil high in oleic acid content have been developed and are desired by oil processors because of improved oxidative stability for broader use in food, fuel and other products. Conventional soybean lines with 80% oleic acid content were generated by combining two mutant genes, mutant S117N FAD2-1A allele from 17D and mutant P137R FAD2-1B allele from PI283327. Thirty five F4:7 high oleic lines with these mutant FAD2-1A and FAD2-1B genes were compared to thirty five F4:7 normal or wild type oleic acid lines for seed contents of the five fatty acids common to soybean, total oil content, total protein content, and seed yield from five crosses grown in six environments. The high oleic genotypes averaged >75% oleic acid content and concentrations of palmitic and linolenic acids were significantly lower (30% lower) than their normal oleic acid counterparts in each environment. When averaged across all locations and populations, seed yield of the high oleic lines were within 2% of the normal oleic lines. Because of the negative correlation of protein with oil content and seed yield shown in many other studies, it was surprising that these high oleic lines averaged significantly higher in protein and oil with similar yield compared to normal oleic lines. These results provided evidence that high oleic soybeans can have comparable yields with the potential to generate more oil with greater functionality and higher protein meal for improved feed and food value compared to soybeans with normal oleic acid content from the same cross.

Book excerpt: BACHLAVA, ELENI. Genetic Control of High Oleic Acid Seed Content in Soybean. (Under the direction of Andrea J. Cardinal and Ralph E. Dewey) The increase of oleic acid concentration in soybean [Glycine max (L.) Merr.] oil improves its nutritional value and oxidative stability; therefore, the incorporation of the high oleate trait in soybean germplasm is required for the commercial success of soybean oil. Little is known, however, about the response to selection for higher oleate content, which is dependent on its heritability in breeding populations, and the correlated responses of other fatty acids and agronomic traits to selection for oleate content, which depends on their genetic correlations with oleate. Furthermore, the lack of knowledge on the genetic factors underlying oleate variation in soybean oilseeds hampers the use of marker assisted selection for high oleate content in soybean breeding programs. The results of this study suggested that oleate heritability was sufficiently high that early generation selection can be effective when practiced on unreplicated lines grown at a single environment. Moreover, this study indicated that selection for higher oleate will result in lower linoleate, linolenate and palmitate content in soybean oil. Also, the significant negative correlation between oleate content and yield implied that the development of high oleate germplasm may be hindered by lower yields. The isoforms of FAD2 gene, which catalyze the desaturation of oleate to linoleate during fatty acid biosynthesis, were mapped in order to investigate their cosegregation with the oleate quantitative trait loci (QTLs) identified. FAD2-1A and FAD2-1B mapped on linkage groups O and I, respectively, while the closely linked FAD2-2A and FAD2-2B isoforms mapped on linkage group L of soybean genome. An oleate QTL with moderate effects was reported in the proximity of FAD2-1B on linkage group I. Also, an oleate QTL with moderate effects was detected on linkage group F, wh.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean (Glycine max [L.] Merrill) oil is an economically important commodity worldwide with many uses. High levels of polyunsaturated fatty acids cause oxidative instability of the oil; however, the DP-3054231-1 transgene confers elevated oleic acid concentrations resulting in oil with increased oxidative stability. The first objective of this thesis was to study the effects of the DP-305423-1 transgene on agronomic and seed traits across multiple genetic backgrounds and environments. An equal number of high oleic (HO) and normal oleic (NO) BC1F4:F6 progeny from four unique populations were grown at four locations in Southern Ontario and two in Northern Iowa. Overall, the difference in mean yield between the HO and NO progeny varied across populations and locations and the HO progeny consistently had lower mean oil concentration and greater mean protein concentration. Differences in 100-seed weight were not consistent across populations or locations. Genomic selection (GS) has been shown to be a valuable tool for performing selection on complex quantitative traits, such as seed oil concentration in soybean. The second objective of the thesis was to evaluate multiple GS models for seed oil concentration using a low-density marker panel in bi-parental, high oleic soybean populations and compare prediction accuracies of six unique training populations (TPs). Prediction accuracy was calculated as the Pearson correlation coefficient between the predicted value of an individual and the 'true' phenotypic value, as determined through multi location field testing. Genomic best linear unbiased predictor (GBLUP) produced the greatest predictability across all populations and training sets, compared to BayesA and BayesB, which had similar predictive ability across populations. Generally, TPs consisting of more individuals had greater predictability; however, variations were observed across populations and models. TPs consisting of individuals from a single location had greater predictability of all genotypes than training populations of equal size comprised of individuals from both locations, indicating potential influence of marker x environment effects across training environments. These results show that genomic selection using a low marker density can be a valuable tool for increasing oil concentration in biparental high oleic, low linolenic soybeans populations.

Book Synopsis Soybean as a Model Crop to Study Plant Oil Genes by : Guohao He
Download or read book Soybean as a Model Crop to Study Plant Oil Genes written by Guohao He and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have numerous fatty acid desaturase (FAD) enzymes regulating the unsaturation of fatty acids, which are encoded by a FAD gene family. The FAD2 genes belong to such family and play a vital role in converting monounsaturated oleic acid to polyunsaturated linoleic acid. Oleic acid has the health benefits for humans, such as reduction in cholesterol level, antioxidation property, and industrial benefits like longer shelf life. The development of genotypes with high oleic acid content in seeds has become one of the primary goals in breeding oilseed plants. The identification and characterization of the FAD2 genes in plants have been an important step to better manipulate gene expression to improve the seed oil quality. The induction of mutations in FAD2 genes to reduce FAD2 enzyme activity has been an integral approach to generate genotypes with high oleic acid. This chapter will describe the FAD2 gene family in the model organism soybean and the correction of mutations in FAD2 genes with the increase of oleic acid content. Leveraging advanced research of FAD2 gene family in soybean promotes the study of FAD2 genes in other legume species, including peanut. The future perspectives and challenges associated with mutations in FAD2 genes will be discussed.

Download or read book Oil Crops written by Johann Vollmann and published by Springer Science & Business Media. This book was released on 2009-09-18 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: When one is privileged to participate long enough in a professional capacity, certain trends may be observed in the dynamics of how challenges are met or how problems are solved. Agricultural research is no exception in view of how the plant sciences have moved forward in the past 30 years. For example, the once grand but now nearly forgotten art of whole plant physiology has given way almost completely to the more sophisticated realm of molecular biology. What once was the American Society of Plant Physiologists’ is now the American Society of Plant Molecular Biology; a democratic decision to indemnify efforts to go beyond the limits of the classical science and actually begin to understand the underlying biological basis for genetic regulation of metabolic mechanisms in plants. Yet, as new technologies open windows of light on the inner workings of biological processes, one might reminisce with faint nostalgia on days long past when the artisans of plant physiology, biochemistry, analytical chemistry and other scientific disciplines ebbed and waned in prominence. No intentional reference is made here regarding Darwinism; the plant sciences always have been extremely competitive. Technology is pivotal. Those who develop and/or implement innovative concepts typically are regarded as leaders in their respective fields. Each positive incremental step helps bring recognition and the impetus to push a scientific discipline forward with timely approaches to address relevant opportunities.

Book excerpt: A mutant tortured and barely alive. A woman restrained by a society she no longer trusts. When Khalisa first sets eyes on the barely conscious mutant, Zielle, she isn’t prepared for the anguish within at seeing firsthand what the scientists in the Dome’s facility are doing to the ‘monsters’ who live outside the air-cleansed compound. But then she’s always rebelled against the rules. Always questioned and defied everything she’s been told since she and her brother, Dwight, were captured and saved from outside, where the chemical fallout would have turned them mutant too. What she and her brother don’t know is that they are dormant mutants whose powers are yet to be triggered. They are also the last hope of saving a mutant clan, whose leader, Zielle, volunteers to be captured by the evil humans so that he can find and rescue the mutant siblings. But it’s only Khalisa he can free, and on the run from the humans who’d do anything possible to recapture them, he has to convince Khalisa that he’s on her side…and that the sizzling chemistry between them is just an added bonus.
