tomato as a highly nutritious vegetable crop is widely grown in the world. hybrid seed is preferably used for tomato production. identification of superior hybrid combination is one of the most important steps in the hybrid breeding programs. breeding of high yielding hybrids is expensive and involves testing large numbers of hybrid combinations in multi-environment trials. successful predictio...

breeding for resistance is one of the main approaches to control diseases. in this approach, there is a necessary for existence a sufficient genetic variability of resistance genes. accordingly, assessing the genetic variability in the available germplasm is needed to manage genetic resources. molecular markers are effective tools to investigate genetic diversity for resistance to pathogens. nb...

Synthetic genetic interactions reveal buffering mechanisms in the cell against genetic perturbations. These interactions have been widely used by researchers to predict functional similarity of gene pairs. In this paper, we perform a comprehensive evaluation of various methods for predicting co-pathway membership of genes based on their neighborhood similarity in the genetic network. We clearly...

Objective: Identity the genetic aspects and major gene influence on energy balance, milk production, fertility, food safety and consumer are the recent interests of genetic and breeding researchers. Methods: Najdi Cattle is the most prominent breeds in Khuzestan province. To do this plan in Shoushtar Najdi Cattle Station, blood samples were taken from 15 Najdi Cattles. DNA was extracted from wh...

olive cultivars with specific characteristics have been developed thanks to iran’s particular climatic conditionsand long-term olive cultivation. the genetic variation and relationships among 40 olive cultivars, as well as 17 unknown genotypes from the national olive collection orchard at tarom research station, zanjan, iran, were evaluated using ssr markers. using 10 microsatellite primer pair...

Giardia duodenalis is a flagellated intestinal protozoan responsible for infections in various hosts including humans and several wild and domestic animals. Few studies have correlated environmental contamination and clinical infections in the same region. The aim of this study was to compare groups of Giardia duodenalis from clinical and environmental sources through population genetic analyse...

for study the genetic diversity and phylogenetic analysis of polymyxa betae keskin , isolated from sugar beet fields in razavi and northern khorasan provinces ,soil of 49 fields were sampled and sugar beet seeds (variety ic) were planted that .after dna extraction, a genomic region comprises of 463 bp of p.betae isolation including 18s r rna، its1 ,5.8srrna ،its2 and 28s rrna was amplified usin...
