For each of the ten groups we reviewed: their taxonomy and geography (with particular regard to establishing the extent to which related uncultivated taxa and populations are potentially
interfertile with social drug plants); identification of wild taxa or populations that are in danger of gene loss or even population extinction; pollen and seed vectors (the vehicles which transport genes from cultivated to non- cultivated populations); documented evidence of hybridization and gene transfer; information on the inheritance of the drugs (which affects the ability of the determining genes to develop the drug in targeted populations); information pertinent to the harmfiilness of the drugs in herbivores; and considerations that endanger particular ecosystems.
Low et al., "Oil palm genome sequence reveals divergence of
interfertile species in old and new worlds," Nature, vol.
Loasoideae): Are
interfertile species and inbred populations results of a recent radiation?
The mating group C was genetically
interfertile strains from rice (Hseieh et al., 1977; Kuhlman, 1982).
Many different forms of New World Junonia tested in lab crosses are
interfertile and produce viable fertile hybrids [39-41], but many of these
interfertile forms are separated geographically or by habitat preference (see below) and would have limited contact in the wild.
galloprovincialis) are
interfertile. In fact, there was no significant difference between pure lines and hybrids in the percentage of eggs which developed into larvae (P > 0.05).
These two taxa are also
interfertile and hybrids have been observed in nature (R.K.
However, if you trace them around the North Pole, at about the same latitude, you find that there is a series of
interfertile sub-species that link the two, each similar in appearance to those either side of it.
The two diploid subspecies are fully
interfertile and an impressive set of genomics tools, including linkage maps, QTL data sets, ESTs, BAC libraries, and arrays is available for analysis of the H genome, which is homeologous with the A, B, and D genomes of hexaploid wheat (Hayes et al., 2003).
Lee Silver resolves the problem by suggesting that there would be intervention in the molecules bonding sperm and ova in such a way that all children who had benefited from such genetic enhancement would not be
interfertile with those who had not benefited from it.
