Wild Bactrian camels (Camela ferus) are listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) and only persist in some of the most remote locations in northern China and southern Mongolia. Although the species has been recognized as an umbrella species for the fragile central Asian desert ecosystem and has been high on the conservation agenda, little is kn...
Many aspects of the historical relationships between populations in a species are reflected in genetic data. Inferring these relationships from genetic data, however, remains a challenging task. In this paper, we present a statistical model for inferring the patterns of population splits and mixtures in multiple populations. In our model, the sampled populations in a species are related to thei...
Rice is the most important crop in the world, acting as the staple food for over half of the world's population. The evolutionary relationships of cultivated rice and its wild relatives have remained contentious and inconclusive. Here we report on the use of whole chloroplast sequences to elucidate the evolutionary and phylogenetic relationships in the AA genome Oryza species, representing the ...
Repeated macrofungal explorations, followed by thorough examination of species through morphology and molecular phylogeny, have made it clear that European American names wild mushrooms were inadvertently misapplied quite often to Asian lookalikes mycologists/taxonomists in the past. Therefore, order reveal this mushroom treasure, recent years, taxonomical research on has been intensified count...
Background: The continuous worldwide increase of consumption of fresh mushrooms has registered in the recent years. The major goal of this study was to determine the microbiological characteristics of wild edible mushrooms and effect of temperature during storage of Morchella conica. Methods: Wild mushrooms of the species Boletus edulis, Cantharellus cibarius, and Leccinum aurantiacum were col...
It has only recently been discovered that the likely origin of some of the world's most important fruit crops, such as apples, apricots and walnuts, lie in a small region of forests in central Asia. The region is home to more than 300 wild fruit and nut species but this unique genetic resource is under major threat, according to a new report which estimated that 90 per cent of this woodland has...
The Caspian Sea and its basin (e.g. Anzali wetland) is one of the natural habitats of wild common carp Cyprinus carpio. In this study the genetic structure of this species. In the south-west of Caspian Sea (the Anzali wetland) was investigated using PCR-RFLP analysis of D-loop region. Two hundred of mature fish were collected from 5 stations (40 individuals from each station) including Siahkesh...
some cerasus sub-genus wild species that are used as rootstocks in sour and sweet cherry propagation can also be employed in breeding programs. the aim of this study was to clearly evaluate some characteristics of subgenus cerasus genotypes to be used in the future cherries' breeding programs. in order to evaluate some morphological characteristics of the vegetative parts as well as seeds ...
this research was investigated to evaluate growth indices and competitive ability of two wheat ) triticum aestivum l. (cultivars in interference with two species of narrow and broad leaf weeds as two separated experiments based on a randomized complete block design with three replications at agricultural faculty of bu-ali sina university, during 2008-2009. in both experiments, alvand and sayson...
abstract seedless barberry (berberis vulgaris l. var. asperma) is one of the few crops that is cultured only in iran and southern parts of khorasan provinces. the origin of this variety is unknown and there has not been any study aiming to identify phylogenic relationships of this plant with other species existing in iran. in this study, aflp markers based on four primer combinations (ecori/tru...
