Populations of phytophagous bugs influenced by crop background and wild plants

Tracing the wild genetic stocks of crop plants.

A number of attempts have recently been made to identify the wild populations that form the founder germplasm stock of our crop plants (Huen et al. 1997; Molina-Cano et al. 1999; Ladizinsky 1999; Zhou et al. 1999; Badr et al. 2000). Some of these works were based mainly on comparative analyses and statistical treatments of genomic DNA polymorphism data (Huen et al. 1997; Molina-Cano et al. 1999...

Introgression of Crop Alleles into Wild or Weedy Populations

The evolutionary significance of introgression has been discussed for decades. Questions about potential impacts of transgene flow into wild and weedy populations brought renewed attention to the introgression of crop alleles into those populations. In the past two decades, the field has advanced with considerable descriptive, experimental, and theoretical activity on the dynamics of crop gene ...

Effects of competition on the fitness of wild and crop-wild hybrid sunflower from a diversity of wild populations and crop lines.

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...

the effects of previewing and providing background knowledge on iranian university efl learners’ comprehension of literary and academic texts

abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
