Barley (Hordeum vulgare) and wheat (Triticum aestivum) possess significant phytase activity in the mature grains. Maize (Zea mays) and rice (Oryza sativa) possess little or virtually no preformed phytase activity in the mature grain and depend fully on de novo synthesis during germination. Here, it is demonstrated that wheat, barley, maize, and rice all possess purple acid phosphatase (PAP) gen...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
Most people associate rice with Asia. But rice is also of African origin. Among the two dozen species of the Oryza genus only two were domesticated, one in Asia (Oryza sativa), the other in West Africa (Oryza glaberrima). While Asia has long been synonymous with the culture of rice, Africa has not. However, a notable exception occurs in isolated communities of north-eastern South America where ...
peace and national security protection and ironic solving of international conflicts become the preliminary foundation of the united nations charter and had been considered as the main responsibilities of the security council, after world war ii and the establishment of united nations organization. therefore, the security council enables to analyze every kind of conflicts and challenges which ...
Seed development dedicates to reserve synthesis and accumulation and uncovering its genetic and biochemical mechanisms has been a major research focus. Although proteomic and transcriptomic analyses revealed dynamic changes of genes and enzymes involved, the information regarding concomitant metabolic changes is missing. Here we investigated the dynamic metabolic changes along the rice grain de...
Indole-3-acetic acid (IAA) synthesis is required for grain-fill in maize and appears to be regulated by cell-wall invertase (CWIN) activity. OsYUC12 is one of three IAA biosynthesis genes we previously reported as expressed during early rice grain development, correlating with a large increase in IAA content of the grain. This work aimed to investigate further the role of OsYUC12 and its relati...
batch adsorption experiments were performed to study adsorption potential of agricultural residues viz. rice straw, wheat straw and salvinia plant biomass for removal of heavy metals such as cr, ni, and cd. plant materials were used in different combinations. heavy metal removal efficiency was more at low metal concentration (35 mg/l). salvinia biomass possessed higher efficiency for removing h...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
There is increasing evidence that global warming affects the development of rice. High temperatures during ripening increase the ratio of undesirable chalky grains followed by deteriorating grain appearance quality. In order to detect quantitative trait loci (QTLs) controlling the occurrence of white-back and basal-white chalky grains of brown rice, QTL analysis was performed using recombinant ...
Genetic relatedness among Indian farmers’ rice varieties were assessed using 24 distinct rice microsatellite markers. The 41 rice genotypes studied included 14 improved varieties and 27 landraces collected from different parts of India. The number of alleles per microsatellite locus ranged from 2 to 4, averaging 2.79 alleles per locus. Polymorphism information content (PIC) values ranged from 0...
