		Oryza sativa is an anuual plant and a member of the family Poaceae (formerly Gramineae), that can grow up to ten feet in height.
		Some chemicals contained within the plant of Oryza sativa are: acetone, ferulic-acid, glycine, isoeugenol and potassium.
		Oryza glaberrima, known as "African rice" or "upland rice", is grown in a non-submerged setting.

	Rice (Oryza sativa)
		Oryza sativa is believed to have originated in lowland tropical areas subject to periodic flooding, and it is under these conditions that rice is still most productive.
		Oryza = riso (Italian), orizo (Greek), arroz (Spanish), ris (French) … and all refer to “..of Oriental origin”.
		There are thousands of cultivars (cultivated varieties) of Oryza sativa, and they can be divided into 2 main groups distinguished by the proportions of 2 types of starch present in the grain.

		Arabidopsis Thaliana is much cheeper than Oryza Sativa to generate in the mass quantities necessary for the extensive experimental research needed to develop an understanding of a plant function such as drought tolerance.
		Both Arabidopsis thaliana and Oryza Sativa are both excellent model organisms, and both have the potential to advance the study of drought tolerance.
		Oryza Sativa is not amenable to large scale experimental research like Arabidopsis is, however, it is of more direct agronomic significance.

		Hybrids of Oryza sativa with species even in the same genome group are highly sterile and may require embryo rescue.
		Commercial varieties of Oryza sativa are neither normally sympatric nor naturally panmictic with the wild species of Oryza.
		To a naturally possible extent, commercial varieties of rice have been exchanging genes among themselves and with the wild species of Oryza all along and there is no evidence of the hybrids surviving to any considerable extent or of having any significant impact on the environment.

	Botany Photo of the Day: Oryza sativa
		Oryza sativa is a staple part of the diet of almost fifty percent of the world’s human population.
		Rice is a cultigen, a “species”; that is the result of human hybridization and selection, i.e., Oryza sativa did not exist prior to human intervention.
		General consensus is that the wild progenitor of Oryza sativa is Oryza rufipogon (see: history of rice cultivation), though some scientists disagree (read the subsection on botany and origin of rice).

	The Oryza Map Alignment Project (OMAP) - NSF Proposal Details
		The long term objective of this proposal is to use BAC libraries and Overgo technology to reconstruct rice chromosome 1 in 6 related Oryza species to examine chromosome evolution in group of closely related species and develop tools for comparative mapping in plant genomes.
		In cases where BAC end sequences from several Oryza species can be shown to both overlap a retrotransposon and are positioned orthologously, mutation rates for this type of DNA can be surmised.
		For example, an Oryza sativa pseudogene that was misannotated as a protein coding gene in the reference sequence, can be caught if it is missing entirely in the wild rice species or has accumulated one or more frameshift or nonsense mutations.

		The phenetic relationship between AA diploid Oryza species, as shown in Figure 6, was similar to those obtained by RFLP [23] and AFLP [24].
		The Oryza species, except for the AA diploids, could not be included in the phenetic analysis, as the Rim2/Hipa-TD marker bands in these species were difficult to match with their corresponding homologous bands in the AA diploids (Fig.
		The distribution of the Rim2/Hipa CACTA elements among Oryza species is particularly prominent in AA genome diploid species, which was corroborated by the results of Southern hybridization using Rim2/Hipa CACTA element [21,25].

		Rice wild relatives (Oryza spp.) are the source of several resistance (R-) genes including those for blast and sheath blight resistance.
		Recently, methodology to identify associations between DNA markers and specific traits was developed and it should be possible to use this methodology to identify R-genes in Oryza spp.
		In order to identify possible new R-genes, associations between the aforementioned SSR markers and disease ratings were determined within each of the three groups.

	For Rice Is Now Oryza Syngenta! - by Devinder Sharma / Opinions / In Motion Magazine
		Thirty-eight years later, as the United Nations dedicates 2004 to the world’s most important staple food once again, celebrating it as the International Year of Rice, the starchy grain has undergone a complete metamorphosis.
		In 1966, the miracle rice seeds that ushered in the green revolution belonged to the species -- Oryza sativa -- a mankind’s heritage.
		Since the time the indica variety of wild rice was known to be growing in the northern and southern slopes of the Himalayas -- and that was some 15,000 years ago -- rice has been regarded as probably God’s greatest gift to human society.

	M.M.P.N.D. - Sorting Oryza names
		One apparent anomaly for example is that glutinous rice is invariably dumped with ordinary rice in the western world but in China the glutinous type is clearly distinguished from the non glutinous kind, this is understandable given the importance of rice in Chinese cuisine.
		Moreover Oryza nivara which is labelled as a wild rice in the Chinese language is also dumped with glutinous and non-gutinous rices which are clearly cultivated, not wild.
		Perhaps its true synonym is Oryza sativa f.

		Rice is two species of grass (Oryza sativa and Oryza glaberrima) native to tropical and subtropical southern and southeastern Asia and in Africa, which together provide more than one fifth of the calories consumed by humans in their global diets
		Two species of rice were domesticated, Asian rice (Oryza sativa) and African rice (Oryza glaberrima).
		Genetic studies suggest that common wild rice, Oryza rufipogon, was the wild ancestor of Asian rice

		Rice (Oryza sativa) is one of the most commonly consumed cereal grains, and as a result, has considerable economic and agricultural importance, despite their potential as a source of genetic material.
		Our principle hypothesis is that genetic diversity exists at the molecular level in wild species of Oryza, and that this diversity can provide useful information regarding the phylogenetic relationships among rice species and permit a more theoretical examination of the evolutionary processes, such as concerted evolution, within Oryza and its nine genomes.
		A phylogeny of Oryza is presented, and modes of evolution are discussed.
