The Honey bee is an important model animal for behavioral study as it is a colonial insect with complex social behavior. Many studies have characterized its fascinating behavioral repatriate, but little is known about the genetic basis of its behavior because of difficulties in maintaining selected stocks and the scarify of genetic markers. However, it is now possible to construct detailed link...

inter simple sequence repeat (issr) markers were used to assess the genetic diversity among 23 outcross and self pollinated populations of fennel collected from different geographical regions of iran and some european countries. the experiment was carried out to determine the effect of self-pollination on morphological traits and genetic diversity in the next generation. fifteen primers produce...

molecular characterization of 19 jatropha accessions that included 15 accessions of j.curcas and 4 different species was carried out using 3 different markers systems. highest polymorphism (96.67%) was recorded by rapd followed by damd (91.02%) and issr (90%). polymorphism information content (pic) was higher for damd (0.873) and almost equal for rapd (0.863) and issr (0.862) markers, whereas r...

Genetic linkage maps were constructed with ampli¢ed fragment length polymorphism (AFLP) and microsatellite markers for the pearl oyster, Pinctada martensii (Dunker), the main bivalve used for marine pearl production in Asia. Twenty-four AFLP and 84 microsatellite primer pairs were used for linkage analysis in a full-sib family with two parents and 78 o¡spring. Of the 2357 AFLP fragments generat...

BACKGROUND AND AIMS The florist's gloxinia is a familiar houseplant in the Gesneriaceae, the botanical family that includes the African violet (Saintpaulia) and other ornamental species. The gloxinia's wild progenitor is Sinningia speciosa (Lodd.) Hiern, a Brazilian endemic. Although it has been cultivated for almost 200 years, little is known about the genetic diversity in S. speciosa, how the...

sardari is one of the most important landraces of common wheat (triticum aestivum l.) that is mainly cultivated in drylands and mountainous area of iran. moreover, it shows a high level of genetic diversity. in the present research a total of 73 sardari wheat ecotypes were evaluated for drought tolerance. genetic diversity was analyzed using amplified fragment length polymorphism (aflp) marker ...

Nicotiana langsdorffii is one of two species of Nicotiana known to express an incompatible interaction with the oomycete Peronospora tabacina, the causal agent of tobacco blue mold disease. We previously showed that incompatibility is due to the hypersensitive response (HR), and plants expressing the HR are resistant to P. tabacina at all stages of growth. Resistance is due to a single dominant...
