Neural-tube defects (NTDs) are considered to be the most common congenital malformations. As Shanxi Province, a poor region in the North of China, has one of the highest reported prevalence rates of NTDs in the world, folate fortification of rice is an excellent alternative to low intake of folate acid pills in this region. This paper investigates the relations between socio-demographic indicat...

Development of marker-free transgenic plants is a technical alternative for avoiding concerns about the safety of selectable marker genes used in genetically modified (GM) crops. Here, we describe the construction of a spontaneous self-excision binary vector using an oxidative stress-inducible modified FLP/FRT system and its successful application to produce marker-free transgenic rice plants w...

China has not commercialized genetically modified (GM) rice, but they are close and many observers believe the time is near when national leaders will “pull the trigger.” After examining the state of biotechnology research on rice in the world, in general, we examine the implications for producers in China, the world’s largest rice economy. To do so, we draw on our work that has appeared in Sci...

The bacterium Bacillus thuringiensis (Bt) produces a wide range of toxins that are effective against a number of insect pests. Identifying the mechanisms responsible for resistance to Bt toxin will improve both our ability to control important insect pests and our understanding of bacterial toxicology. In this study, we investigated the role of MAPK pathways in resistance against Cry1Ca toxin i...

Genetically modified (GM) foods are evaluated carefully for their ability to induce allergic disease. However, few studies have tested the capacity of a GM food to act as an adjuvant, i.e. influencing allergic responses to other unrelated allergens at acute onset and in individuals with pre-existing allergy. We sought to evaluate the effect of short-term feeding of GM Bacillus thuringiensis (Bt...

BACKGROUND Genetically modified crops (GM crops) have been developed to improve the agricultural traits of modern crop cultivars. Safety assessments of GM crops are of paramount importance in research at developmental stages and before releasing transgenic plants into the marketplace. Sequencing technology is developing rapidly, with higher output and labor efficiencies, and will eventually rep...

Detection methods and data from molecular characterization of genetically modified (GM) events are needed by stakeholders of public risk assessors and regulators. Generally, the molecular characteristics of GM events are incomprehensively revealed by current approaches and biased towards detecting transformation vector derived sequences. GM events are classified based on available knowledge of ...

This study investigates consumer preferences for newly introduced gene-edited (GE) food. We focus on how risk and ambiguity aversion affect consumers’ willingness to pay (WTP) avoid genetically modified (GM) food or GE whether the impacts of differ between GM collected data in 2020 through a nationwide online survey China. The multiple price list method is used estimate premiums that consumers ...

OBJECTIVE To produce the monoclonal antibodies (mAbs) against hygromycin B phosphotransferase (HPT) and to develop immunoassay based on mAbs for biosafety assessment of HPT in genetically modified rice (GM rice). METHODS BALB/c mice were immunized with purified recombinant 6His. HPT protein, and the conventional hybridoma technology was used to generate the monoclonal hybridoma cells. ELISA a...
