The present study was performed to evaluate the food safety of TT51-1, a new type of genetically modified rice that expresses the Cry1Ab/Ac protein (Bt toxin) and is highly resistant to most lepidopteran pests. Sixteen male and 16 female cynomolgus monkeys were randomly divided into four groups: conventional rice (non-genetically modified rice, non-GM rice), positive control, 17.5% genetically ...

This paper looks at differences in spatial and temporal variation of rice yields in China and Brazil. We find that rice yields in China have converged over time and that rice production has become more and more homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily due to variations in upland rice yields. Three hypotheses are put forward to explain the different beha...

In cooperation with the Louisiana Rice Research Board, the Louisiana State University Rice Research Station and the USA Rice Federation, we conducted a questionnaire survey in 2002 to estimate the economic impacts of blackbirds on the rice industry in Louisiana, Texas, Arkansas, California, and Missouri. Survey areas in rice producing states were identified based on the 2001 National Agricultur...

BACKGROUND Metabolic syndrome poses a serious health threat in Asian countries. Rice is a staple food in Korea, and carbohydrate intake is associated with the risk of MetS. We hypothesized that various rice-eating patterns in a carbohydrate-based diet would have different effects on the risk of MetS. METHODS Participants were 26,006 subjects enrolled in the Korean Genome and Epidemiology Stud...

BACKGROUND AND AIMS Transgene escape through gene flow from genetically modified (GM) crops to their wild relative species may potentially cause environmental biosafety problems. The aim of this study was to assess the extent of gene flow between cultivated rice and two of its close relatives under field conditions. METHODS Experiments were conducted at two sites in Korea and China to determi...

Actinomycetes are involved in important environmental processes such as the decomposition of organic matter. In this study, we examined the impact of crop rotation on the actinomycetes community colonizing rice straw residues in soil over 3 field seasons by means of Denaturing Gradient Gel Electrophoresis (DGGE) fingerprinting analysis of actinomycetes 16S rRNA gene fragments amplified from fie...

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...

We developed a multiplex polymerase chain reaction (PCR) coupled with ligation detection reaction and universal array system for screening genetically modified rice and further identifying specific transgenes in rice. Three common elements in transgenic rice (CaMV 35S promoter, FMV 35S promoter and nos terminator) with species and internal controls (rice actin, 18S rRNA) were used for screening...

Emerging evidence supporting chronic disease fighting properties of rice bran has advanced the development of stabilized rice bran for human use as a functional food and dietary supplement. A global and targeted metabolomic investigation of stabilized rice bran fermented with Saccharomyces boulardii was performed in three rice varieties. Metabolites from S. boulardii-fermented rice bran were de...
