BACKGROUND/OBJECTIVE Despite potential benefits granted by genetically modified (GM) fruit trees, their release and commercialization raises concerns about their potential environmental impact, and the transfer via pollen of transgenes to cross-compatible cultivars is deemed to be the greatest source for environmental exposure. Information compiled from field trials on GM trees is essential to ...

Global synthesis indicates that limitation of plant fecundity by pollen receipt (pollen limitation) is positively related to regional plant diversity and is higher for self-incompatible than self-compatible species. While self-incompatible species are always dependent on pollinating agents, self-compatible species may be pollinator-dependent or autofertile. This should cause variation in pollen...

in the beginning of 1980s named as entrepreneurship decade, a large number of entrepreneurship researchers attempted to determine certain characteristics that distinguished entrepreneurs from non-entrepreneurs by identifying certain characteristics inherent in potential entrepreneurs in order to predict entrepreneurial behavior. among the characteristics identified, little empirical research ha...

Small populations of self-incompatible plants may be expected to be threatened by the limitation of compatible mating partners (i.e., S-Allee effect). However, few empirical studies have explicitly tested the hypothesis of mate limitation in small populations of self-incompatible plants. To do so, we studied wild pear (Pyrus pyraster), which possesses a gametophytic self-incompatibility system....

The article titled; Distribution of hepatitis C virus genotypes in Iranian patients with congenital bleeding disorders, revealed the genotype distribution of HCV in Iranian hemophilic patients. 4 In this study, results demonstrate genotype 1a was the most frequent HCV genotype (58%), followed by genotype 3a (18.5%) and genotype 1b (14.7%). Mixed genotypes were also detected in 6.2%. These findi...
