The resistance (R) genes and defense response (DR) genes have become very important resources for the development of disease resistant cultivars. In the present investigation, genome-wide identification, expression, phylogenetic and synteny analysis was done for R and DR-genes across three species of rice viz: Oryza sativa ssp indica cv 93-11, Oryza sativa ssp japonica and wild rice species, Or...
Background and purpose: Ischemia-reperfusion injuries (I/RI) are the major causes of liver failure after various types of liver surgeries, particularly liver transplantation. Reactive oxygen species (ROS) are the major causes of such injuries, therefore, antioxidant therapy to attenuate hepatic lesions is preferred. We aimed to evaluate the effects of silibinin, a potent radical scavenger, on l...
barley (hordeum vulgare l.) is a model plant, as genetic and physiological studies are concerned. abiotic stresses such as drought adversely affect the growth of plants. the objective of this experiment was to identify the responsive genes to osmotic stress, using macroarray (covering 13050 genes). rna was extracted from 5 barley genotypes in stress as well as in normal conditions at 3 times of...
DNA methylation is a type of epigenetic changes that directly affects DNA. In mammals, DNA methylation is essential for fetal development and stem cell differentiation and this phenomenon essentially occurs within the CpG islands. In this study, two methods were used to study the DNA methylation profile of cow genome. In the first method, the DNA methylation profile of the differentially expres...
Existing encoding schemes and index structures proposed for XML query processing primarily target the containment relationship, specifically the parent–child and ancestor–descendant relationship. The presence of preceding-sibling and following-sibling location steps in the XPath specification, which is the de facto query language for XML, makes the horizontal navigation, besides the vertical na...
The ever-increasing of spatial datasets and the widely application of the complex computation have motivated the emergence of distributed algorithms to process spatial operations efficiently. The R-tree index is broadly used by researches as a distributed spatial structure for indexing and retrieval of spatial objects. However, a big challenge has arisen, that is, how to check the consistency o...
