Since our purpose here was to identify areas where each of the species has a realistic chance of surviving and reproducing, either naturally (rice CWRs) or through human intervention (cultivated rice), potential overestimations are justified.
Our results imply that the domestication process accelerated large-scale genomic deletions in the lineage of Asian cultivated rice and that the close relatives of cultivated rice have the potential to restore the lost traits.
Contrasting current and future estimates of total area suitable for rainfed agriculture (included both cultivated and uncultivated) suggests potential increases for most regions.
In particular, the most actual is to find ways to increase the adaptation potential of cultivated plants with the use of nanopreparations in stressful conditions.
Though wild rice species are phenotypically inferior and have predominantly been used as a source of genes for resistance to pests and diseases (Hodgkin et al. 2007), they also possess the genetic value necessary to improve the yield potential of cultivated rice (Xiao et al. 1998).
This was to be expected given that the wild parent was measured to possess an overall greater AO potential than cultivated lettuce.
Here, the AO potential of cultivated lettuce (L. sativa cv. Salinas) was significantly lower than that of the wild progenitor (L. serriola), with notable differences in phenolic composition.
Major attention was paid to collecting, conserving and studying crop species and wild relatives of cultivated plants that possessed potential value for agriculture and breeding.
Although our genotypic sampling was limited, we investigated the SNPs which were present in the non-cultivated genotypes but fixed in the cultivated genotypes for their potential involvement in either domestication or speciation.
While these studies show that cultivated alleles maintain the potential to introgress into wild sunflower populations, they do not provide insight into how selection operates to introgress particular traits and their underlying alleles.
According to Eizenga et al. [ 27], the wild Oryza species which are closely related to cultivated rice are a potential source of important traits including new resistance genes to fight pests like sheath blight and blast diseases.
