The availability of a comprehensive set of resources including an entire annotated reference genome, sequenced alternative accessions, and a multitude of marker systems makes Arabidopsis thaliana an ideal platform for genetic mapping. PCR markers based on INsertions/DELetions (INDELs) are currently the most frequently used polymorphisms. For the most commonly used mapping combination, Columbia×...
The genus Lolium is one of the most important groupings of temperate forage grasses, including about eight recognized species that are native to some temperate and subtropical regions of the northern hemisphere. We examined genetic relationships among 18 accessions representing all Lolium species using RAPD markers. Among 50 random primers that we screened, 13 gave reproducible amplification ba...
Red rice is a troublesome weed in rice-growing areas of the southern U.S. Red rice in Arkansas may be diverse enough to warrant some adjustments in weed control programs. A study was conducted at the Rice Research and Extension Center (RREC), Stuttgart, Ark., in 2003 to determine the phenotypic diversity of red rice in Arkansas. One hundred thirty-six red rice accessions were collected from 26 ...
Fescue is an important forage species growing in wide climates. Genetic variation was estimated for 18 accessions of Festuca arundinacea using 12 ISSR primers in payame Noor university of Kermanshah. In total 87 bands (loci) were obtained.77 bands out of 87 were polymorph in accessions. The mean polymorphism percentage was 89.05 among Fescue accessions.The greatest polymorphism percentage were ...
Nigella sativa L. (black cumin) belonging to the Ranunculaceae family, is one of the most important medicinal plants and wild and cultivated forms of this plant is used in Iran. Genetic diversity of 27 accessions of N .Sativa L. from different places of Iran was characterized by morphological characteristics and data was analyzed using univariate and multivariate analyses. ANOVA revealed high s...
Regional variations of antioxidant capacity and phenolic properties in the Iranian jujube collection
Background & Aim: Fruits from the jujube plant (Ziziphus jujuba) possess health-promoting effects and medicinal properties. Jujube has a long history of usage as a remedy in Iranian traditional medicine and is recommended for the treatment of some diseases. This study investigated the variations in antioxidant capacities (AOX), total phenol (TPH), total flavonoid (TF) ...
Species of pathogenic fungi Alternaria SPP developed early blight disease on potato. In order to evaluate the resistance levels of wild diploid accessions of National Plant Gene bank of Iran, a factorial randomized complete design with three replications was performed in National Plant Gene Bank under in vitro and greenhouse condition during 2007-2008 and disease symptoms were recorded. Based o...
This study aimed to investigate the genetic variability among guava accessions and wild Psidium species of the Embrapa Semiárido germplasm collection by using microsatellite loci to guide genetic resources and breeding programs, emphasizing crosses between guava and other Psidium species. DNA was extracted using the 2X CTAB method, and polymerase chain reaction products were analyzed on 6% dena...
Glyphosate has been the most intensely herbicide used worldwide for decades, and continues to be a single tool for controlling weeds in woody crops. However, the adoption of this herbicide in a wide range of culture systems has led to the emergence of resistant weeds. Glyphosate has been widely used primarily on citrus in the Caribbean area, but a study of resistance in the Caribbean islands of...
For most crops, like Capsicum, their diversity remains under-researched for traits of interest for food, nutrition and other purposes. A small investment in screening this diversity for a wide range of traits is likely to reveal many traditional varieties with distinguished values. One objective of this study was to demonstrate, with Capsicum as model crop, the application of indicators of phen...
