It is revealed that the EE genome species is most closely related to the DD genome progenitor that gave rise to the CCDD genome, and that the AA genome lineage, which contains cultivated rice, is a recently diverged and rapidly radiated lineage within the rice genus.

The isolation and functional analysis of the rice GIF1 (GRAIN INCOMPLETE Filling 1) gene that encodes a cell-wall invertase required for carbon partitioning during early grain-filling suggest that GIF1 is a potential domestication gene and that such a domestication-selected gene can be used for further crop improvement.

Gene flow occurs with a noticeable frequency from cultivated rice to its weedy and wild relatives, and this might cause potential ecological consequences and it is recommended that isolation zones should be established with sufficient distances between GM rice varieties and wild rice populations to avoid potential outcrosses.

Comparative genomic analysis reveals that the kiwifruit has undergone an ancient hexaploidization event (γ) shared by core eudicots and two more recent whole-genome duplication events, particularly in the asterid lineage.

The results suggested that: the St, H, P, and W genomes in polyploid Elymus were donated by Pseudoroegneria, Hordeum, Agropyron and Australopyrum, respectively; and some Elymus species showed multiple origin and experienced recurrent hybridization.
Genetic diversity and origin of weedy rice (Oryza sativa f. spontanea) populations found in North-eastern China revealed by simple sequence repeat (SSR) markers.

Recent changes in farming practices and cultivation methods along with less weed management may have promoted the re-emergence and divergence of weedy rice in North-eastern China.
Gene flow from cultivated rice to the wild species Oryza rufipogon under experimental field conditions.

- Biology, MedicineNew Phytologist
- 1 March 2003
The results indicated that gene flow from cultivated rice to O. rufipogon occurred at a considerable rate, and isolation measures should be considered when deploying transgenic rice in the sympatric regions of the wild rice, and when establishing in situ conservation of the species.
A comparative study of genetic relationships among the AA-genome Oryza species using RAPD and SSR markers

- 19 September 2003
It is demonstrated from this study that both RAPD and SSR analyses are powerful methods for detecting polymorphisms among the different AA-genome Oryza accessions, and the RAPD analysis provides a more-informative result in terms of the overall genetic relationships at the species level compared to the SSR analysis.
Gene Flow from Genetically Modified Rice and Its Environmental Consequences
Transgenic rice varieties with higher yields, greater tolerance of biotic and abiotic stresses, resistance to herbicides, improved nutritional quality, and novel pharmaceutical proteins will be ready for commercialization within the next few years.
