Several more- or less-elaborated rice genome sequences have been produced recently using different strategies. It has become possible to compare them and to unravel the major features of the rice genome in terms of nucleotide composition, repeats, gene content and variability. It has also become possible to compare the rice and Arabidopsis genomes and to evaluate rice as a model genome.

synthetic dyes are among the most common contaminants of the environment. therefore, the aim of this study was investigation the removal of basic blue 41 (bb41) and methylene blue (mb) from industrial effluents by useing raw and modified rice stems. in this study raw and modified rice stems treated chemically with citric acid (ca) and were used to explore the potentiality of rice stems for remo...

pyricularia oryzae (tel. magnaporthegrisea) is currently used as a fungal model for plantmicrobeinteraction studies as well as an indicative model for anticancer drug discovery. thepresent study introduces the optimal condition in which p. oryzae grows and sporulates beston common culture media. we have considered three fungal culture media, i.e. pda, pca andwa, based on which p. oryzae sporula...

A rapid and nondestructive way to measure protein and amylose content of rice was put forward based on near infrared(NIR) spectral technology. The NIR spectra were acquired from 13 varieties of rice with the wavelength from700 to 1100nm. The objectives of the present study were to establish forecasting model to find out the relationship between the absorbance of the spectrum and the main compon...

Although Arabidopsis is well established as the premiere model species in plant biology, rice (Oryza sativa) is moving up fast as the second-best model organism. In addition to the availability of large sets of genetic, molecular, and genomic resources, two features make rice attractive as a model species: it represents the taxonomically distinct monocots and is a crop species. Plant structural...

Quantification of rice biophysical properties is important not only for rice growth monitoring and cropping management, but for understanding carbon cycle in agricultural ecosystems. In this study, a rice canopy scattering model (RCSM) was firstly utilized to simulate rice backscatter with a root mean square error (RMSE) <1 dB in comparison with the C-band, HH-polarization Radarsat-2 images. An...

As an economy experiences high growth rates, some sections of the population enjoy a more than proportionate rise in income. This leads to an increased allocation of resources towards the production of luxury goods. Since the production of luxury goods often requiresmore resources than the production of necessary goods, itmay reduce not only the production of necessary goods, but also total pro...

This study assessed the determinants of intensity of improved rice varieties adoption using the Tobit model and also employed. The Heckman Two-stage model was used to identify the determinants of market participation and its potential impact on farming households’ welfare in three states selected from the three notable rice producing ecologies in Nigeria. A crosssectional data of 600 rice farme...

The purpose of this paper is to analyze the world rice market through a Structure-Conduct-Performance (SCP) framework utilizing annual data from 1970 to 2007. Since World War Two, the world rice market has been very unstable, with rice prices experiencing volatile swings in both rice price and rice availability. Therefore, a SCP framework can provide crucial insight into the world rice market f...

This article applies a general equilibrium model to analyse the impact of new rice technology on household income and uses agricultural household survey data from China to test the implications of this model. It is shown that, when a new rice technology becomes available, the adopting household will reallocate resources to increase rice production and reduce the production of other goods. Meanw...
