Ayu (Plecoglossus altivelis), one kinds of valuable cultured fish species, show almost no morphological difference between male and female until sexual maturity. Here, we report the identification of sex-linked markers for the ayu, based on Amplified Fragment Length Polymorphism (AFLP) generated from cultured fish (15 males and 15 females) by using 63 different primer combinations. Genomic frag...

The nutritional qualities of wild and cultured Clarias gariepinus from Oba Reservoir, Ikose, Ogbomoso, Oyo State, Nigeria, the fish Department Fisheries Aquaculture, State Ministry Agriculture Mineral Resources, were evaluated. proximate composition, mineral element composition essential amino acids profile sampled species evaluated using standard laboratory procedures. results was observed to ...

Gene flow between crop fields and wild populations often results in hybrids with reduced fitness compared to their wild counterparts due to characteristics imparted by the crop genome. But the specifics of the evolutionary outcome of crop-wild gene flow may depend on context, varying due to local environmental conditions and genetic variation within and among wild populations and among crop lin...

Triatoma infestans, the major vector of Chagas disease south of the Amazon in South America, has a large distribution of wild populations, contrary to what has previously been stated. These populations have been suspected of being the source of reinfestation of human habitats and could impede the full success of vector control campaigns. This study examined gene flow between intra-peridomestic ...

Background: Avian chlamydiosis is a zoonotic disease ofbirds caused by the intracellular bacterium Chlamydia psittaci. Avianchlamydiosis leads to severe respiratory disease in young turkeys and eggproduction losses in layers. OBJECTIVES: Due to paucity of information about theprevalence of chlamydial infection in the turkey population in Iran, this studywas conducted to detect chlamydial infect...

Citron (Citrus medica L.) is a medicinally important species of citrus native to India and occurs in natural forests and home gardens in the foothills of the eastern Himalayan region of northeast India. The wild populations of citron in the region have undergone rapid decline due to natural and anthropogenic disturbances and most of the remaining individuals of citron are found in fragmented na...

Rosa canina L. is a member of Rosaceae family, which is well-known for its high phenolic contents. These compounds are known to possess antioxidant and antiradical effects. In order to compare the antioxidant and antiradical activity of wild Rosa phenolic extracts, two wild Rosa species (Rosa canina L. and Rosa pimpinellifolia L.) were selected from Takab, Oshnavieh and Qasemloo Valley of Urmia...

Pistacia atlantica is the most important tree species for the economy of many rural areas in west of Iran, but no effort has been made for the genetic improvement of this species. The aim of this investigation was to study the genetic variation and inheritance of early growth traits in P. atlantica. For this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...
