“…Being an important oil crop globally, soybean yield and quality improvement are always key objectives for plant breeders. In an experiment, a total of 20 QTL governing linoleic acid, oil and palmitic acid were identified, varying in their expression (Silva et al, 2021). Enhancing the content of soybean storage protein while increasing the ratio of glycinin to β-conglycinin is of great importance for soybean breeding plans and soybean food products.…”

The soybean is one of the most significant legume crops around the globe and serves as a source of dietary components for humans and animals. It has a higher percentage of protein compared to any other crop. Soybean yield and quality have been affected by many environmental factors. The genetic mechanism of yield and quality is still not clearly understood. Hence there is still a need to investigate the major potent factors to shed light on the mechanism behind yield and quality traits in soybean. Recently, a lot of significant work, including novel QTL, genes, and CRISPR-based genome editing in soybeans, has been done, which opened new doors of hope. The current review has presented detailed work done previously. We have also discussed the role of different breeding techniques in the conventional way of soybean improvement. The genetic factors regulating yield, quality, and disease resistance could be further cloned and transferred into elite cultivars to attain higher output in the current situation of changing environment. The integrated use of several techniques, like CRISPR/Cas9, next-generation sequencing, omics approaches, would be a fruitful way to improve soybean yield and quality. Besides this, hybridization, mass selection, pure line selection, backcross breeding, and pedigree selection should be adopted to develop novel soybean cultivars. This review concluded that soybean yield and quality improvement could be enhanced by exploring its genetic mechanism using several molecular and conventional methods.

“…In addition to the known variants described above, studies have identified numerous additional QTL that impact oil content in soybean (Li et al., 2021; Silva et al., 2021; Sung et al., 2021; Yao et al., 2020). This suggests that there remains a significant degree of untapped genetic potential for modification of this trait.…”

Diversity of fatty acid biosynthesis genes across the soybean pangenome

et al. 2023

Soybean (Glycine max) is a major crop that contributes more than half of global oilseed production. Much research has been directed towards improvement of the fatty acid profile of soybean seeds through marker assisted breeding. Recently published soybean pangenomes, based on thousands of soybean lines, provide an opportunity to identify new alleles that may be involved in fatty acid biosynthesis. In this study, we identify fatty acid biosynthesis genes in soybean pangenomes based on sequence identity with known genes and examine their sequence diversity across diverse soybean collections. We find three possible instances of a gene missing in wild soybean, including FAD8 and FAD2-2D, which may be involved in oleic and linoleic acid desaturation, respectively, although we recommend follow-up research to verify the absence of these genes. More than half of the 53 fatty acid biosynthesis genes identified contained missense variants, including one linked with a previously identified QTL for oil quality. These variants were present in multiple studies based on either short read mappings or alignment of reference grade genomes. Missense variants were found in previously characterized genes including FAD2-1A and FAD2-1B, both of which are involved in desaturation of oleic acid, as well as uncharacterized candidate fatty acid biosynthesis genes. We find that the frequency of missense alleles in fatty acid biosynthesis genes has been reduced significantly more than the global average frequency of missense mutations during domestication, and missense variation in some genes is near absent in modern cultivars. This could be due to the selection for fatty acid profiles in seed, though future work should be conducted towards understanding the phenotypic impacts of these variants.

“…Soybean oil is one of the most widely consumed vegetable oils globally, whereby, increasing it is of great interest. As genetic factors have the greatest influence over soybean nutritional composition, genetic improvement programs have been the focus of much research aimed at maximizing oil content (SILVA et al, 2021). Thus, studies showed significant variability among cultivars for oil content in the grain (FARIA et al, 2018;FLAJŠMAN et al, 2019).…”

Oil content and economic water productivity of soybean cultivars under different water availability conditions

et al. 2023

This research evaluated the yield, water productivity, and economic water productivity for the oil content of three soybean cultivars under different water conditions. The experiments were conducted in the 2017/2018 and 2018/2019 harvests. The experimental design consisted of a two-factor randomized block, with the first factor of 5 irrigation depths, based on the reference evapotranspiration (ETO), plus the treatment without irrigation and the second factor was 3 soybean cultivars. Results reported oil yield and productivity were higher for the depths of 75% (crop 1) and 100% of ETO (crop 2). For the evaluations of water productivity and economic water productivity, the highest results were obtained at the level of 50% in crop 1 and 25% and 50% in crop 2. Cultivar BRASMAX Ponta had the highest values for oil production and BRASMAX Valente for oil yield, in both crops. In Crop 1, the BRASMAX Valente cultivar had the highest results in water productivity and economic water productivity, and in Crop 2, the BRASMAX Ponta cultivar had the highest values. Supplemental irrigation favored the increase in oil production and oil productivity. For a more efficient and economical use of water, it is necessary to use smaller irrigation depths.
