Origin of seed shattering in rice (Oryza sativa L.)

Planta, 2007
A critical evolutionary step during rice domestication was the elimination of seed shattering. Wild rice disperses seeds freely at maturity to guarantee the propagation, while cultivated rice retains seeds on the straws to make easy harvest and decrease the loss of production.

Investigation of tocotrienol biosynthesis in rice (Oryza sativa L.)

Food Chemistry, 2013
Rice tocotrienol (T3) has gained attention due to its physiological activities (e.g., antiangiogenesis). However, the biosynthetic pathway for T3 production in rice grain has not been well studied. We hypothesized that T3 biosynthesis enzymes and/or precursors play an important role in T3 production in whole grain.

Arsenic Accumulation and Metabolism in Rice (Oryza sativa L.)

Environmental Science & Technology, 2002
The use of arsenic (As) contaminated groundwater for irrigation of crops has resulted in elevated concentrations of arsenic in agricultural soils in Bangladesh, West Bengal (India), and elsewhere. Paddy rice (Oryza sativa L.) is the main agricultural crop grown in the arsenic-affected areas of Bangladesh.

Wide compatibility in rice (Oryza sativa L.)

Euphytica, 1992
Wide compatible varieties (WCVs) show normal spikelet fertility in crosses with Indica and Japonica rice varieties. Crosses of Indica and Japonica varieties frequently show high spikelet sterility which prevents exploitation of heterosis for grain yield.

Somatic Embryogenesis in Rice (Oryza sativa L.)

1995
Cultivated rice belongs to the genus Oryza, in the grass family Poaceae (Gramineae). There are 22 species within the genus, 20 wild species and 2 cultivated species, O. glabberima (African rice) and O. sativa (common, or Asian rice).Oryza sativa is commonly divided further into two subspecies, indica (or tropical rice) and japonica (or temperate rice ...

Transpiration efficiency of rice (Oryza sativa L.)

Field Crops Research, 2009
Abstract Transpiration efficiency (TE), defined as the total dry matter produced per unit of water transpired, is an important crop characteristic, especially when water resources are becoming scarcer in many regions. But, in contrast to other major food crops, very little is known about the TE of rice (Oryza sativa L.) and its dynamics in relation ...

Somaclonal genetics of rice, Oryza sativa L.

Theoretical and Applied Genetics, 1983
The inheritance and variations of some traits of more than 2,000 somatic cell derived plants of rice (Oryza sativa L.) were investigated in the second and third generations (T2 and T3) of regenerated plants (somaclones). The percentages of multiploids occurring in somaclones ranged from 0-13.3 in nine varieties (or hybrids) of 'Hsien' (indica) group ...

Cybridization in Oryza sativa L. (Rice)

2001
Rice is one of the most important crops in the world, and feeds about 40% of the world population. The yield of rice needs to be increased, since a world food crisis has been predicted for the early 21st century. World annual rice production must increase from its current value of 520 to 810 million tons by 2025 (Hossain 1996).

Genetic Improvement of Rice (Oryza sativa L.)

2017
The emerging challenges of increasing global population, decreasing arable lands, and escalating threats posed by climate change exert pressure on the genetic improvement of rice to increase its yield potential in irrigated and nonirrigated lands as it is the staple food of more than three billion people. Advances in genetics and molecular biology have
