Major histocompatibility complex (MHC) represents an important genetic marker for manipulation to improve the health and productivity of cattle. It is closely associated with numerous disease susceptibilities and immune responses. Bovine MHC, also called bovine leukocyte antigen (BoLA), is considered as a suitable marker for genetic diversity studies. In cattle, most of the polymorphisms are lo...

the purpose of this study was to identify the rate of polymorphism in bm6444, inra13 and orahh35 microsatellite markers associated with inhibin gene in sanjabi sheep. for this purpose, blood samples were taken randomly from 100 sanjabi sheep (78 females and 22 males) at mehregan breeding station at kermanshah. modified salting out method was employed for extracting dna. subsequently, polymerase...

Molecular markers have proven to be invaluable tools for assessing plants’ genetic resources by improving our understanding with regards to the distribution and the extent of genetic variation within and among species. Recently developed marker technologies allow the uncovering of the extent of the genetic variation in an unprecedented way through increased coverage of the genome. Markers have ...

F OLLOWING absorption of DNA by competent cells, genetic transformation ensues with a probability that is characteristic for each particular genetic marker (HOTCHKISS and MURMUR 1954; LERMAN and TOLMACH 1957). Thus, specific incorporation, defined as the amount of DNA which must be incorporated in order to obtain one transformant, varies according to the genetic marker employed. With the develo...

Cucurbita maxima is one of the most widely cultivated vegetables in China and exhibits distinct morphological characteristics. In this study, genetic linkage analysis with 57 simple-sequence repeats, 21 amplified fragment length polymorphisms, 3 random-amplified polymorphic DNA, and one morphological marker revealed 20 genetic linkage groups of C. maxima covering a genetic distance of 991.5 cM ...

Genetic diversity estimation of plant materials is one of the important pre-breeding activities in breeding field crops. Twenty-one microsatellite markers used to assess genetic diversity and relationship of 68 sunflower genotypes (Helianthus annuus L.). All of 21 pairs of SSR (Simple Sequence Repeats) markers produced a total number of 49 polymorphic bands. DNA fragments ranged from 9...

different species of streptomyces are common in most types of soil. some certain species are plant pathogenic especially on potato. this study was conducted to evaluate genetic diversity among some local streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of iran. repetitive dna elements (box, eric and rep) as genetic markers were used for diversity stu...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic nephropathy, which is characterized by replacement of renal parenchyma with multiple cysts. In Iran, the disease prevalence within the chronic hemodialysis patient population is approximately 8-10%. So far, three genetic loci have been identified to be responsible for ADPKD. Little information is available concernin...

By analyzing genetic similarity of rhodococci actinobacteria seven phylogenetic groups are allocated on the base alkane- 1-monooxygenases sequences. R. qingshengii F2-2 genome have been shown to alkane-1-monooxygenase genes affiliated five different types. We assume use diversity as a molecular marker identify Rhodococcus species.
