“…Little variation in amino acid concentrations was observed across environments and maturity groups (Table 2). Deficiency in sulfur-containing amino acids, Met and Cys is the main limitation of soy protein for animal feed (Ufaz and Galili, 2008). In this study the difference between the population mean and the population maximum for Cys was 2.6g kg -1 crude protein (Figure 1), representing a 14% increase at the upper extreme (Table 1); similarly the difference between the population mean and the population maximum for Met was 1.5g kg -1 crude protein (Figure 2), representing a 8% increase at the upper extreme (Table 1).…”

“…Non-essential amino acids can be produced and stored by the animal. However, both are important components of a healthy diet (Ufaz and Galili, 2008). Since, soybean meal is primarily used in the poultry and swine industry the essential amino acids for each are reported.…”

“…However genetic approaches have resulted in relatively limited success. This is mostly due to limited availability of genetic resources for plant breeding, and the fact that genetic traits for high contents of Lys, Trp or Met are generally associated with abnormal plant growth because these traits do not operate in a seed specific manner (Ufaz and Galili, 2008). In contrast results from genetic engineering appear to be more promising.…”

RESUMEN:Las leguminosas grano tienen un alto potencial en alimentación humana y animal siendo una importante fuente de proteínas así como de otros compuestos beneficiosos para la nutrición y salud. La proteína es uno de los ingredientes más demandados y las leguminosas grano son una delas fuentes más sostenible de proteína. Sin embargo, no todas las leguminosas grano son igual de nutritivas, variando la calidad con la composición de aminoácidos y su digestibilidad. En este artículo revisaremos los conceptos de calidad de la proteína y discutiremos las posibilidades de mejora genética. Para abordar con éxito la mejora de la calidad de la proteína será de gran ayuda disponer de bases de datos con los perfiles de aminoácidos y de digestibilidad, así como de información cuantitativa sobre los compuestos bioactivos que reducen la digestibilidad, todo ello unido a mé-todos fiables para su evaluación. El desarrollo de variedades de leguminosas con una proteína de mayor calidad, más ajustadas a las necesidades tanto humanas como del ganado, permitirá una mayor eficiencia nutritiva, reduciendo el contenido de proteína en la dieta y los costes asociados, así como la excreción de nitró-geno, disminuyendo el impacto medioambiental.PALABRAS CLAVE: Leguminosas grano; calidad de la proteína; aminoácidos; digestibilidad; factores anti nutritivos ABSTRACT: Grain legumes, also called pulses, play a key role in the nutritional improvement of food and feed. These legumes are important sources of protein as well as other nutritional compounds. Today, protein is one of the most sought after ingredients in the market and grain legumes represent one of the most sustainable protein sources. However, not all grain legume proteins are nutritionally equal. Their quality varies and depends on their amino acid composition and digestibility. In this article, we review concepts related to grain legume protein quality and discuss challenges regarding their genetic improvement. A comprehensive database of grain legume amino acid profiles and protein digestibility is needed to address the matter of protein quality in grain legume breeding. This database will be enhanced by quantitative information on digestibility-reducing bioactive compounds and the development of reliable screening tools. The achievement of higher protein quality grain legume varieties, better adjusted to animal and human requirements, will cut dietary protein content, associated costs and nitrogen excretion, thus reducing the environmental impact.

“…is a legume crop, and its seeds are among few plant-derived food sources that contain useful concentrations of all essential amino acids [1]. Amino acids (AA) are key elements for proper growth and development of animals, and both essential and non-essential amino acids are important for healthy diet [2]. In soybean, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are essential AA for humans, but histidine is considered semi-essential, whereas arginine, alanine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, proline, serine, and tyrosine are considered non-essential AA [2].…”

. (2015) Mapping of QTL Associated with Seed Amino Acids Content in "MD96-5722" by "Spencer" RIL Population of Soybean Using SNP Markers. AbstractLimited information is available on the genetic analysis of amino acid composition in soybean seeds. Previously, quantitative trait loci (QTLs) for seed isoflavones, protein, oil, and fatty acids were identified in the "MD96-5722" by "Spencer" and other RIL populations. There were wide variations for these seed constituents among the RIL populations. Therefore, the objective of this study was to identify QTLs controlling different amino acids content in soybean seeds. To achieve this objective, ninety-two F5:7 recombinant inbred lines (RIL), developed from a cross of MD96-5722 and Spencer, using a total 5376 Single Nucleotide Polymorphism (SNPs) markers, were used. The RILs were genotyped by using 537 polymorphic, reliably segregating SNP markers, developed from the Illumina Infinium SoySNP6K BeadChip array. A total of 13 QTLs were identified with three QTLs for threonine on the linkage group (LG) A1, C2, and B2. Two QTLs were identified for each of the amino acids proline on LG D1a and B2, serine on LG A1 and C2, tryptophan on LG K and G, and cysteine on LG A1 and K. One QTL was identified for arginine on LG N and histidine on LG J. The new QTLs findings for seed amino acid will facilitate the development of soybean cultivars with higher protein and amino acid quality to help meet the industry and consumer needs.* Corresponding author.
