Freezing is one of the most important climatic factors affecting almond products in Isfahan province. Therefore, it is important to use a rapid method for assessing the resistant cultivars and wild species of these plants. Evaluation of electrolyte leakage (EL) from freezing damaged tissues of almond is an appropriate method for this purpose. In the present work, the effect of freezing on the r...

Betanodavirus is the leading cause of viral mortality in fish worldwide and a major barrier to the spread of fisheries and aquaculture. Due to the increase in aquaculture in the Persian Gulf and the occurrence of some disease symptoms in farmed and wild fish in the region, screening of Betanodavirus-sensitive fish became important. Therefore, to prevent economic losses and reduce aquatic reserv...

Background: Satureja bachtiarica Bunge, an endemic species with relatively wide distribution, is traditionally used as a medicinal and spice plant in Iran. Objective: Essential oils composition, antioxidant activities and phenolics content of wild and cultivated S. bachtiarica of Yazd origin were determined in this study. Methods: Hydrodistilled essential oils were analyzed by GC-FID and GC-M...

Background and purpose: Wild rats are considered as an important spreading factor of contamination in urban areas. During recent years, the wild rats were extensively distributed in Tehran. Therefore, it is important to investigate the antibiotic resistance of enteric bacteria isolated from rats, because of the possibility of antibiotic resistance transmission to human. The aim of this study ...

  Citrus stubborn disease is caused by the helical mollicute Spiroplasma citri. The pathogen is naturally transmitted by sap feeding leafhopper vectors. In the present study attempts were made to detect S. citri in presumptive vectors. Leafhoppers were collected from various wild and cultivated plants in citrus growing areas in Jirfot. Fifteen leafhopper species were identified and 12 species w...

Seedless barberry (Berberis vulgaris L. var. asperma) is one of the few crops that is only cultivated in eastern parts of Iran. As a new crop there has not been any study to identify phylogenetic relationships of this plant with other related species existing in Iran. In this study, Amplification fragment length polymorphism (AFLP) markers based on four selected primer combinations (EcoRI/Tru1I...

Eggplant (Solanum melongena) is related to a large number of wild species that are a source of variation for breeding programmes, in particular for traits related to adaptation to climate change. However, wild species remain largely unexploited for eggplant breeding. Detailed phenotypic characterization of wild species and their hybrids with eggplant may allow identifying promising wild species...
