“…The seed protein composition depends upon various environmental factors such as temperature, photoperiod and nutrition etc during seed development (Arslanoglu et al, 2011;Kumar et al, 2013). Alterations in the nutritional conditions may cause a wide range of morphological, physiological and biochemical changes by modification of genes and enzymes expression and thus protein synthesis and activity (Fabre and Planchon, 2000). Protein synthesis in soybean is reported to be highly influenced by minerals such as phosphorus, potassium, nitrogen and sulphur (Peak et al, 1997;Utsumi, et al, 2002;Mahmoodi et al, 2013).…”

) and combined application of nitrogen (N) and sulphur (S) were investigated. Application of S alone or combined with N significantly increased plant height, number of seeds per pod and total seed yield. Sulphur-containing amino acids viz., methionine and cysteine increased significantly (P≤0.05) by all the treatments in comparison to control and maximum increase of 1.3 fold was observed by urea application. The contents of different protein fractions viz., albumin, globulin and glycinin (a subfraction of globulin) increased under the effect of N and S applied alone or in combination from 30 DAP to maturity with maximum accumulation at maturity as compared to control (without N or S application). Gypsum @ 20 kg S ha -1 resulted in higher accumulation of glycinin (11S) relative to β-conglycinin (7S) fraction of globulin protein in soybean seed thereby increasing 11S:7S ratio indicating improvement in soybean seed quality. The current study showed that improvement of soybean nutritional quality can be achieved by application of gypsum @ 20 kg S ha -1 along with recommended N doses under agroclimatic conditions of Punjab.

“…Embryos receive sugars and amino acids and convert them into storage reserves through primary metabolism. Thus, the accumulation of protein and oil is controlled by both the maternal (Fabre and Planchon, 2000;Nakasathien et al, 2000;Pipolo et al, 2004) and seed (Wilcox, 1998;Narvel et al, 2000;Hernández-Sebastià et al, 2005) genotypes, which complicates efforts to gain fundamental understanding of the process.…”

Carbon and Nitrogen Provisions Alter the Metabolic Flux in Developing Soybean Embryos

Soybean (Glycine max) seeds store significant amounts of their biomass as protein, levels of which reflect the carbon and nitrogen received by the developing embryo. The relationship between carbon and nitrogen supply during filling and seed composition was examined through a series of embryo-culturing experiments. Three distinct ratios of carbon to nitrogen supply were further explored through metabolic flux analysis. Labeling experiments utilizing [U- ]asparagine were used to monitor differences in carbon allocation. The analyses revealed that: (1) protein concentration as a percentage of total soybean embryo biomass coincided with the carbon-to-nitrogen ratio; (2) altered nitrogen supply did not dramatically impact relative amino acid or storage protein subunit profiles; and (3) glutamine supply contributed 10% to 23% of the carbon for biomass production, including 9% to 19% of carbon to fatty acid biosynthesis and 32% to 46% of carbon to amino acids. Seed metabolism accommodated different levels of protein biosynthesis while maintaining a consistent rate of dry weight accumulation. Flux through ATP-citrate lyase, combined with malic enzyme activity, contributed significantly to acetyl-coenzyme A production. These fluxes changed with plastidic pyruvate kinase to maintain a supply of pyruvate for amino and fatty acids. The flux maps were independently validated by nitrogen balancing and highlight the robustness of primary metabolism.

“…This affects the yield of soybean plants, despite their ability to obtain N via biological fixation, given the positive correlation between yield and nitrogen assimilation in the growth stage R 2 . This occurs because, according to Fabre & Planchon (2000), there is a sharp decline in the biological nitrogen fixation after R 2 , accompanied by increased nitrate assimilation up to the stage R 6 . Additionally, the authors found a correlation between biological fixation in R 2 and R 5 and protein content in the beans.…”

A fast growth in the use of substances that increase soybean yield through physiological or morphological changes, such as cytokinin, has taken place in recent years. This study aimed at assessing the effect of the application time of cytokinin as kinetin on soybean crops. The experiment was carried out under field conditions, using four treatments (control and kinetin at the vegetative stages V4, V6 and V4 + V6), with five replications, in completely randomized blocks. Physiological (nitrate reductase and peroxidase activity, H2O2 content and lipid peroxidation) and phenometric parameters (leaf and root dry mass), as well as yield, were evaluated. The application of kinetin at V4, V6 or V4 + V6 increased the activity of the nitrate reductase enzyme and reduced stress (evaluated via lipid peroxidation and hydrogen peroxide content), in addition to raising the dry matter content. All these characteristics resulted in increased yield. However, the most significant effects were caused by the application of kinetin at V6, which increased yield in 20 %, in relation to the control.
