| Oryza longistaminata, or African red rice, is a close relative of both cultivated rice species, African rice (O. glaberrima) and Asian rice (O. sativa). Its occurrence has not been reported for the US
|
| The phylogeny of the genus Oryza has been studied using numerous molecular markers, however, the results are often divergent. Red rice is the only rhizomatous species belonging to the AA-genome complex
|
| The prospective of generating rhizomatous cultivated rice is especially attractive for the Asian regions suffering from severe soil erosion problems due to annual cultivation procedures. The fact that the genetic origins of perenniality in Oryza longistaminata are similar to those in Sorghum halepense indicates this trait might have already existed in a common ancestor some 50 MYA, before the species evolved
|
| Accessions of red rice resistant to bacterial leaf blight have been used to isolate responsible genes, which were transformed into cultivated rice
|
| Wild rice species are viewed as a potential source of useful resistance traits for the improvement of cultivated rice
|
| To introduce the genes of interest into the target species, transformation methods have been developed for Oryza sativa. Whereas no transformation protocols for red rice have been published until now, regeneration of plantlets from callus has been accomplished
|
| In Africa, red rice sometimes serves as grain source and cattle food
