The nitrogen-fixing symbiosis between legume plants and Rhizobium bacteria is the most prominent plant-microbe endosymbiotic system and, together with mycorrhizal fungi, has critical importance in agriculture. The introduction of two model legume species, Lotus japonicus and Medicago truncatula, has enabled us to identify a number of host legume genes required for symbiosis. A total of 26 genes...

the effect of flour extraction rate on flour composition, dough rheological characteris-tics and the quality of iranian flat breads (lavash, taftoon and barbari) and their staling rate was investigated. flours with different extraction rates (70, 75, 80, 83, 86, 88, 90 and 93) were subjected to different tests. resultes indicated that, by increasing the extraction rate, the amount of protein, f...

Abstract Structural, thermal and energetic properties of quinoa, kiwicha kañiwa native Andean-pseudocereal flours have been studied. Moisture, protein fat contents also metallic semi-metallic levels were, in general, within the range values reported literature. Empirical formulas determined as CH 1.87 O 0.81 N 0 . 06 S 0.0015 , 1.90 0.82 05 0.0019 1.76 0.73 0.0017 respectively. The elemental ca...

Growing understanding of the relationship between nutrition and human health has led to an increase in consumption alternative crops, new cereal varieties foods with higher nutritional values. In this study we compared contents functional-technological properties spelt (Triticum spelta L.) bread wheat (T. aestivum whole-meal flours, obtained from genotypes grown at same field trial, their corre...

the aim of this study was to evaluate the capability of the empirical (large scale) and fundamental (small scale) rheological tests to differentiate between wheat flours of different harvest years. in order to provide flours affected by different climatic conditions, harvest years 2004 and 2005 characterized by high temperatures and large amounts of rainfall were chosen. moreover, a control whe...

in order to determine the role of plant leaf area in radiation distribution within the canopy and a better understanding of how crops and weeds intercept light a study of the complexity of plants is necessary. the  effect of intercropping on leaf area distribution and dry matter accumulation in corn, soybean and weeds canopy was studied in a  field experiment at a research field of tehran unive...

Most plant lectins exhibit other properties. Some also bind plant growth regulators, the cytokinins, which are small hydrophobic molecules derivate from adenine [5,6]. They are secreted proteins and are found in vacuoles, cell walls, or intercellular spaces, of just about every plant organ [7]. Legume root lectins, are involved in the recognition and binding of Rhizobium and Brudyrhizobium sp. ...
