“…Of these, the β-conglycinin is the vicilin (legume globulin storage protein that protects against pathogens) storage trimeric protein of soybeans, composed of three peptides; α, α´ and β. Generally, oil makes up about 19% of the soybean dry weight whereas the storage proteins make up about 40% of the dry seed weight mostly consisting of β-conglycinin ( Liu et al., 2022 ). The significant increase in glycinin and β-conglycinin encoding proteins provides the mechanistic details of SRB02-mediated plant growth promotion in soybean.…”

Plant growth-promoting rhizobacteria (PGPR) colonize plant roots, establish a mutualistic relationship with the plants and help them grow better. This study reports novel findings on the plant growth-promoting effects of the PGPR Bacillus aryabhattai. Soil was collected from a soybean field, PGPR were isolated, identified, and characterized for their ability to promote plant growth and development. The bacterium was isolated from the soybean rhizosphere and identified as B. aryabhattai strain SRB02 via 16s rRNA sequencing. As shown by SEM, the bacterium successfully colonized rice and soybean roots within 2 days and significantly promoted the growth of the GA-deficient rice cultivar Waito-C within 10 days, as well as the growth of soybean plants with at least six times longer shoots, roots, higher chlorophyll content, fresh, and dry weight after 10 days of inoculation. ICP analysis showed up to a 100% increase in the quantity of 18 different amino acids in the SRB02-treated soybean plants. Furthermore, the 2-DE gel assay indicated the presence of several differentially expressed proteins in soybean leaves after 24 hrs of SRB02 application. MALDI-TOF-MS identified β-conglycinin and glycinin along with several other proteins that were traced back to their respective genes. Analysis of bacterial culture filtrates via GCMS recorded significantly higher quantities of butanoic acid which was approximately 42% of all the metabolites found in the filtrates. The application of 100 ppm butanoic acid had significantly positive effects on plant growth via chlorophyll maintenance. These results establish the suitability of B. aryabhattai as a promising PGPR for field application in various crops.

“…There are five central FAs presented in soybean seeds, including stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), linolenic acid (C18:3), and palmitic acid (C16:0), whose composition directly determined the soybean oil quality. Soybean seed protein consists mainly of storage proteins such as glycinin (11S globulin) and conglycinin (7S globulin) ( Liu et al., 2022 ).…”

“…In addition, we also discuss the challenges and prospects for developing high-yield soybean cultivars with high oil or protein content. As the biochemical synthesis of oils in the seed has been widely studied and well-reviewed ( Bates et al., 2013 ; Xu and Shanklin, 2016 ; Song et al., 2017 ; Liu et al., 2022 ; Yang et al., 2022a ), we will not repeat these comments here.…”

“…The oil content of soybean seeds ranges from 8.3 to 27.9%, and protein concentration varies from 34.1 to 56.8% depending on the soybean varieties and cultivation conditions (Wilson, 2004). Soybean oil is generated and stored mainly as fatty acids (FAs), triacylglycerols (TAGs), and tocopherols (Liu et al, 2022). There are five central FAs presented in soybean seeds, including stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), linolenic acid (C18:3), and palmitic acid (C16:0), whose composition directly determined the soybean oil quality.…”

As a leading oilseed crop that supplies plant oil and protein for daily human life, increasing yield and improving nutritional quality (high oil or protein) are the top two fundamental goals of soybean breeding. Seed size is one of the most critical factors determining soybean yield. Seed size, oil and protein contents are complex quantitative traits governed by genetic and environmental factors during seed development. The composition and quantity of seed storage reserves directly affect seed size. In general, oil and protein make up almost 60% of the total storage of soybean seed. Therefore, soybean’s seed size, oil, or protein content are highly correlated agronomical traits. Increasing seed size helps increase soybean yield and probably improves seed quality. Similarly, rising oil and protein contents improves the soybean’s nutritional quality and will likely increase soybean yield. Due to the importance of these three seed traits in soybean breeding, extensive studies have been conducted on their underlying quantitative trait locus (QTLs) or genes and the dissection of their molecular regulatory pathways. This review summarized the progress in functional genome controlling soybean seed size, oil and protein contents in recent decades, and presented the challenges and prospects for developing high-yield soybean cultivars with high oil or protein content. In the end, we hope this review will be helpful to the improvement of soybean yield and quality in the future breeding process.
