“…The principal storage proteins are glycinin (11S) and β-conglycinin (7S) and constitute over 70 % of soluble protein (3). Their content, ratio and dynamics of biosynthesis vary with soybean varieties and environment (4)(5)(6)(7)(8). Glycinin (m.w ∼360 kDa) is a protein with compact quaternary structure stabilized via disulfide, electrostatic and hydrophobic interactions.…”

Soy protein products such as flour, concentrates and isolates are used in food formulation because of their functionality, nutritional value and low cost. To obtain their optimal nutritive and functional properties as well as desirable flavor different treatments are used. Soybean proteins can be modified by physical, chemical and enzymatic treatments. Different thermal treatments are most commonly used, while the most appropriate way of modifying soy proteins from the standpoint of safety is their limited proteolysis. These treatments cause physical and chemical changes that affect their functional properties. This review discusses three principal methods used for modification of soy protein products, their effects on dominant soy protein properties and some biologically active compounds

“…Due to the lack of either spontaneous or mutagen-induced mutant with decreased amount of β subunit and the feature that β subunit content is easily to be affected by numerous factors (ABA, drought, sulfur-nitrogen deficiency et al), mapping of β subunit content-related QTL lagged behind the study in α and α' subunit (Holowach et al 1984;Gayler and Sykes 1985;Bray and Beachy 1985;Kim et al 1999;Blanuša et al 2000). The identification of Yangyandou, a stably inherited landrace in various environment made it feasible for us to map β subunit content-related QTL directly.…”

“…In earlier studies, most of these mutants were characterized as lacking α, α', (α+β), (α'+α) or (α'+α+β) , until recently a lot of varieties with low level of β subunit content has been identified from minicore collection of Chinese soybean germplasm or other collections, however quite few of them were β subunit-null (Kitamura and Kaizuma 1981;Kitamura et al 1984;Ladin et al 1984;Tsukada et al 1986;Kaizuma et al 1989;Odanaka and Kaizuma 1989;Takahashi et al 1994;Liu et al 2006;Wang et al 2008). This was probably because the accumulation of β subunit was easily be affected by numerous stresses, including ABA, drought, and sulfur-nitrogen deficiency (Holowach et al 1984;Murphy and Resurreccion 1984;Gayler and Sykes 1985;Bray and Beachy 1985;Kim et al 1999;Blanuša et al 2000).…”

Soybean seed storage protein is one of the most important plant vegetable protein, and β subunit is of great significance to enhance soybean protein quality and processing property. F2 segregated population and residual heterozygous lines (RHL) derived from the cross between Yangyandou (low level of β subunit) and Zhonghuang13 (Normal level of β subunit) were used for mapping of β subunit content. Our results showed that β subunit content was controlled by a single dominant locus, qBSC-1 (Beta subunit content), which was mapped to a region of 11.9cM on chromosome 20 in F2 population of 85 individuals. This region was narrowed down to 2.5 cM between BARCSOYSSR_20_0997 and BARCSOYSSR_20_0910 in RHL with a larger population size of 246 individuals. There were 48 predicted genes within qBSC-1 region based on the reference genome (Glyma 1.0, Williams 82), including the two copies of β subunit coding gene CG4. An InDel marker developed from a TT insertion in one copy of CG4 promoter region in Yangyandou cosegregrated with BARCSOYSSR_20_0975 within qBSC-1 region, suggesting that this InDel marker maybe a useful marker for MAS.

“…During soybean seed development the four main stages can be observed: morphogenesis and cell division, cell enlargement, seed maturation, and ultimately the release of moisture, and period of seed dormancy. Synthesis of proteins and oils takes place during the growth phase of seed cells (BLANUŠA et al, 2000). Therefore, the growing conditions at this stage were significantly correlated with protein and oil content in soybean seed (ĐORĐEVIĆ et al, 2010).…”

Stability of protein and oil content of 13 soybean varieties were examined using linear model across seven locations and during six years. Due to heterogeneity of environments all year/locations was distributed in to two groups, based on achieved yield. Stability of protein content differed in the low and high yielding environments, while average values show only minor differences. In contrast, oil content stability was slightly changed in the low and high yielding environments, while the average oil content were significantly higher in the low yielding environments. Environmental factors influenced the correlation between oil and protein content in soybeans. Negative correlation between protein and oil content was observed only in the high yielding environments, while varieties in low yielding environments lack this well known inverse relation
