Device to device communication is the interest of fifth generation where the User Equipments (UEs) are capable to directly communicate with other device with partial involvement of base station (BS). However, devices that are not in proximity area, communicate with other devices (relay). This relay selection is done by Base Station (Network Assisted). Network assisted Multihop device to device ...

Marker-assisted selection holds promise because genetic markers provide completely heritable traits than can be measured at any age in either sex and that are potentially correlated with traits of economic value. Theoretical and simulation studies show that the advantage of using marker-assisted selection can be substantial, particularly when marker information is used, because normal selection...

Pearl millet is a staple food crop for millions of people living in the arid and semi-arid tropics. Molecular markers have been used to identify genomic regions linked to traits of interest by conventional QTL mapping and association analysis. Phenotypic recurrent selection is known to increase frequencies of favorable alleles and decrease those unfavorable for the traits under selection. This ...

to identify qtls controlling grain yield and yield components, an f2 population consisting of 188 plants derived from the cross between two rice pure lines, binam and kadous, were grown in research field of faculty of agricultural sciences, university of guilan, rasht, iran, in 2008, and were recorded for 9 important traits related to grain yield. to construct linkage map, 85 marker of ssrs and...

Genotyping is a critical step for molecular marker-assisted selection in rice. Rice genomic DNA samples for genotyping are typically isolated from living tissues such as seedlings. This requires the germination of all candidate seeds and extraction of DNA from the seedlings. Currently, an ideal individual is selected from a very large number of plants, which is time- and labor-consuming, requir...

The IGF1 gene (insulin-like growth factor 1) is a candidate gene for marker-assisted selection strategies. A single nucleotide polymorphism in the promoter region (IGF1/SnaBI) has been reported to be associated with production traits in several cattle breeds. Here, we report its allelic frequencies in Charolais and Beefmaster breeds; we confirm its association with three growth traits: weaning ...

Infertility affects around 15% of human couples and in many countries approximately 1-4% of babies are born following Assisted Reproductive Technologies (ART). Several ART techniques are used and these differentially affect the sex ratio of offspring successfully produced. These direct effects on sex ratio also have the potential to influence, indirectly, the sex ratios of offspring born to unt...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci were developed for Prunus sibirica to investigate genetic diversity, population genetic structure, and marker-assisted selection of late-blooming cultivars in the breeding of P. sibirica. • METHODS AND RESULTS Using a magnetic bead enrichment strategy, 19 primer pairs were developed and characterized across 40 individuals from three P. si...

We suggest a new approximation for the prediction of genetic values in marker-assisted selection. The new approximation is compared to the standard approach. It is shown that the new approach will often provide substantially better prediction of genetic values; furthermore the new approximation avoids some of the known statistical problems of the standard approach. The advantages of the new app...

Short straw is a desired trait in oat germplasm (Avena sativa L.). Marker-assisted selection, a key tool for achieving this objective, is limited by the presence and number of available markers. Here, we have attempted to develop markers sufficiently linked to a gene specifying short straw so that marker-assisted selection could be applied. Bulked-segregant analysis was used to identify anonymo...
