bean root rot caused by plant pathogenic fungus, fusarium solani, is considered one of the most important diseases of bean in the world and in iran. because of economic importance of bean and the lack of information on population diversity of the pathogen in zanjan province, a research was conducted to study phenotypic, genotypic and pathogenicity variation of pathogen isolates and to assess pa...

This study aimed to evaluate the genetic diversity and identify potato cultivars by RAPD and SSR markers. The genomic DNA of 16 potato cultivars was amplified with 25 RAPD primers that generated 92 polymorphic bands and 20 SSR primer pairs that produced 136 polymorphic bands. The dendrograms generated by cluster analysis distinguished the cultivars genetically although the dendrograms were not ...

Synechococcus are distributed throughout the world's oceans and are composed of diverse genetic lineages. However, as they are much less abundant than Prochlorococcus in oligotrophic open oceans, their in-depth genetic diversity cannot be investigated using commonly used primers targeting both Prochlorococcus and Synechococcus. Thus, in this study, we designed a primer specific to the 16S-23S r...

The genetic diversity of 10 Machilus thunbergii populations in eastern China was analyzed using inter-simple sequence repeat markers. The populations showed high genetic diversity, with an overall population genetic diversity of 0.2343. Genetic diversity varied largely among populations, and populations with the highest genetic diversity were mainly from the eastern and western parts of the nat...

BACKGROUND Keeping in view the havoc situation of dengue fever in Pakistan, the current study was designed to demonstrate the genetic variations, gene flow and rate of migration from Lahore and Faisalabad. METHODS The larvae were collected from both natural and artificial breeding places from each collection site. The adult mosquitoes were collected by means of sweep net and battery-operated ...

castor (ricinus communis l.) is one of the most ancient medicinal oil crops in the world. it has been vastly distributed in different parts of iran. in the present study, the inter simple sequence repeat (issr) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of iran. totally, 16 issr primers amplified 166 loci, of whic...

Random amplified polymorphic DNA (RAPD) is a simple, fast and cost effective method for assessing genetic diversity of plant varieties. The reproducibility of the RAPD amplification was affected by several factors, therefore causing misinterpretation. In this study, we analyzed the effect of changing the concentration of magnesium chloride, template genomic DNA and Taq DNA polymerase with the o...

Random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) markers were used to assess the genetic diversity in 31 species of mangroves and mangrove associates. Four AFLP primer combinations resulted in the amplification of 840 bands with an average of 210 bands per primer combination and 11 RAPD primers yielded 319 bands with an average of 29 bands per primer. Th...
