PLANT GENE DOUBLING. "The total chromosome number also may double by combining the chromosome sets of a single species. Of the 260,000 known species of plants, as many as half may have originated in this way." https://lnkd.in/ejwXt8N View in LinkedIn

REPRODUCTIVE ISOLATION. "The role of sexual selection as a selective force in plant speciation is still controversial, in contrast to the situation in animals." http://onlinelibrary.wiley.com/doi/10.1111/nph.13756/full View in LinkedIn

PRION EPIGENETIC SWITCH. "The mammalian prion species barrier, which prevents the spread of scrapie and bovine spongiform encephalopathy to man, has been the focus of intense research efforts. Our data show that for the yeast [PSI+] prion, the species barrier results from a remarkable specificity in interaction between the prion protein itself, mediated by a well-defined epitope in the PrD. Because prion domains are modular, fusion to prion domains could potentially allow prion-based regulation of a broad range of proteins." https://lnkd.in/ebZGb4M View in LinkedIn

PLANTS. "Currently, it is unclear whether the evolution of reproductive isolating barriers is under simple genetic control or due to more complex additive and/or epistatic control, involves loci of major or minor effect, and whether genetic architecture is dependent on the type of reproductive isolating barrier." https://lnkd.in/eGmuRdp View in LinkedIn

PLANT SPECIATION. "The relative role of genic changes versus the chromosomal rearrangements in the evolution of intrinsic postzygotic reproductive isolation now appears to be on the verge of resolution with the implementation of modern molecular techniques." https://lnkd.in/eGmuRdp View in LinkedIn

SPECIATION GENES. "The cloning of genes involved in plant speciation, followed by molecular population genetic analysis, will allow us to reach our ultimate goal: an understanding of the role of microevolutionary forces in the evolution of reproductive isolation." https://lnkd.in/eGmuRdp View in LinkedIn

REPRODUCTIVE ISOLATION. "Recent molecular analyses of a handful of genes that are involved in maintaining reproductive isolation between species (speciation genes) have provided some striking insights. In particular, it seems that despite being strongly influenced by positive selection, speciation genes are often non-essential, having functions that are only loosely coupled to reproductive isolation." https://lnkd.in/ey8kwaB View in LinkedIn

SPECIES BARRIER AND EPIGENETICS. "Evolutionary biologists have long recognized that the sterility and inviability of species hybrids must involve incompatible epistatic interactions between two (or more) genes. The first pair of such hybrid incompatibility genes has now been identified." https://lnkd.in/eV72BRp View in LinkedIn
