The genomics of speciation-with-gene-flow [PDF]
Trends in Genetics, 2012 The emerging field of speciation genomics is advancing our understanding of the evolution of reproductive isolation from the individual gene to a whole-genome perspective. In this new view it is important to understand the conditions under which 'divergence hitchhiking' associated with the physical linkage of gene regions, versus 'genome hitchhiking ...

, 2019 In this chapter, we first present characteristics of carrots that will affect gene flow and discuss dispersal via pollen by insect pollinators and via seeds by wind and animals. Although carrot is often referred to as a biennial, we introduce the various life history strategies observed in wild carrot populations as these can impact population growth ...

Mechanisms of gene flow in archaea
Nature Reviews Microbiology, 2017Archaea are diverse, ecologically important, single-celled microorganisms. They have unique functions and features, such as methanogenesis and the composition of their cell envelope, although many characteristics are shared with the other domains of life, either through ancestry or through promiscuous horizontal gene transfer.

Debate over what is a species was already considered old hat when Darwin wrote his seminal abstract (as he called it) more than 150 years ago.1 Endless papers, workshops, and symposia have been presented in an effort to "solve" the species problem. Yet, here we are, at it again. Has there been any progress? I believe that there has been, and that among

, 2003 By comparing potential and actual risks in both fields of agriculture, with or without GMOs, we need a clear view of the similarities and differences. Raamsdonk (1993) has given a scheme of gene flow, whether natural or influenced by human activity.

Gene flow in an almond orchard [PDF]
Theoretical and Applied Genetics, 1991 Gene flow by pollen between trees is essential for nut set in commercial almond orchards, due to the self-incompatibility of almond cultivars used. A study of gene flow has been carried out in an orchard composed of single rows of a "pollinating" cultivar between every double row of the most commercially desirable cultivar, Nonpareil. This "two-to-one"

Experimental studies of the evolutionary biology of lichen fungi have been hampered by massive difficulties of in vitro culture and artificial crosses are still not possible. Gene flow in these organisms is demonstrated here for the first time by the analysis of secondary products in the progeny of individuals from natural populations of mixed ...

Gene expression is a highly interconnected multistep process. A recent meeting in Iguazu Falls, Argentina, highlighted the need to uncover both the molecular details of each single step as well as the mechanisms of coordination among processes in order to fully understand the expression of genes.
