almonds are self incompatible, the incompatibility being controlled by a multi allelic (s-alleles) single gene. the incompatibility alleles were studied in 96 samples of wild almonds and related prunus species from 10 taxonomic groups. polymerase chain reactions were carried out with six primer sets including: three degenerate primer pairs (paconsi-f(fam)/em-pc1consrd, paconsi-f(fam)/em-pc3cons...
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...
Domestication of crops based on artificial selection has contributed numerous beneficial traits for agriculture. Wild characteristics such as red pericarp and seed shattering were lost in both Asian (Oryza sativa) and African (Oryza glaberrima) cultivated rice species as a result of human selection on common genes. Awnedness, in contrast, is a trait that has been lost in both cultivated species...
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...
Detailed demographic data on wild Asian elephants have been difficult to collect due to habitat characteristics of much of the species' remaining range. Such data, however, are critical for understanding and modeling population processes in this endangered species. We present data from six years of an ongoing study of Asian elephants (Elephas maximus) in Uda Walawe National Park, Sri Lanka. Thi...
Since 2002, H5N1 highly pathogenic avian influenza (HPA1) viruses have been associated with deaths in numerous wild avian species throughout Eurasia. We assessed the clinical response and extent and duration of viral shedding in 5 species of North American ducks and laughing gulls (Larus atricilla) after intranasal challenge with 2 Asian H5N1 HPAI viruses. Birds were challenged at approximately...
The Asian tiger mosquito, Aedes albopictus, is a highly successful invasive species that transmits a number of human viral diseases, including dengue and Chikungunya fevers. This species has a large genome with significant population-based size variation. The complete genome sequence was determined for the Foshan strain, an established laboratory colony derived from wild mosquitoes from southea...
