Genetic Dissection of ICP-Detected Nutrient Accumulation in the Whole Seed of Common Bean (Phaseolus vulgaris L.)

Abstract

Nutrient transport to grain legume seeds is not well studied and can benefit from modern methods of elemental analysis including spectroscopic techniques. Some cations such as potassium (K) and magnesium (Mg) are needed for plant physiological purposes. Meanwhile, some minerals such as copper (Cu), iron (Fe), molybdenum (Mo), and zinc (Zn) are important micronutrients. Phosphorus (P) is rich in legumes, while sulfur (S) concentration is related to essential amino acids. In this research, the goal was to analyze a genetic mapping population of common bean (Phaseolus vulgaris L.) with inductively coupled plasma (ICP) spectrophotometry to determine concentrations of and to discover quantitative trait loci (QTL) for 15 elements in ground flour of whole seeds. The population was grown in randomized complete block design experiments that had been used before to analyze Fe and Zn. A total of 21 QTL were identified for nine additional elements, of which four QTL were found for Cu followed by three each for Mg, Mn, and P. Fewer QTL were found for K, Na and S. Boron (B) and calcium (Ca) had only one QTL each. The utility of the QTL for breeding adaptation to element deficient soils and association with previously discovered nutritional loci are discussed.

“…However, the assisted selection with molecular markers can be a viable alternative to the biofortification programs in common beans. Recent studies revealed the discovery of two quantitative trait loci (QTL) associated with the potassium concentration in a recombinant inbred line of common bean (F 9:11 generation), one QTL was found for calcium, and three QTL´s were found for magnesium (Blair et al, 2016).…”

“…An essential element is an element that if absent or removed from the diet or intake can cause a consistent and reproducible misfunctioning of a physiological process in an organism [19]. Bone development in human beings are requires Ca and if taken in sufficient amount can prevent fractures and bone malformations [20,21]. In the same way, K and Na are required for nerve impulses and ion transport through membranes of tissues; P and Mg are required by the cells for the production of ATP [21,22].…”

In the same way, K and Na are required for nerve impulses and ion transport through membranes of tissues; P and Mg are required by the cells for the production of ATP [21,22]. On the contrary, excessive intakes of these minerals can result in toxicity though most minerals have a fairly wide range of adequate intake making deficiency or toxicity relatively rare if proper diets are taken.…”

“…The occurrence of Zn is not common though it is an integral part of some enzymes such as DNA polymerase thereby making Zn deficiency to lead to poor growth and delay in the development of sexual organs [23]. Plants need B in seed production and humans for development of the central nervous system and of bones [21,24]. Cu is necessary in the reduction of oxidative stress [25].…”

Drought Stress Response in Agricultural Plants: A Case Study of Common Bean (Phaseolus vulgarisL.)

“…The biggest producers are Brazil, USA and Mexico, while millions of tons are produced annually in Africa. Its high levels of protein and carbohydrate make common bean a staple in food, and it is an important source of vitamins and minerals, including iron, magnesium, potassium, zinc, selenium and calcium [1][2][3][4].…”
