PLOS 08/08/14 Transgenic Bacillus thuringiensis (Bt) Rice Is Safer to Aquatic Ecosystems than Its Non-Transgenic Counterpart. Abstract Rice lines genetically modified with the crystal toxin genes from Bacillus thuringiensis (Bt) have experienced rapid development, with biosafety certificates for two Bt rice lines issued in 2009.
There has still been no commercial release of these lines yet due to public concerns about human health and environmental risks. Some studies confirmed that Bt rice was as safe as conventional rice to non-target organisms when pesticides were not applied, however, pesticides are still required in Bt rice to control non-lepidopteran pests. In this study, we assessed the environmental effects of two Bt rice lines expressing either the cry1Ab/1Ac or cry2A genes, respectively, by using zooplanktons as indicator species under normal field management practices using pesticides when required. PLANT BIOTECHNOLOGY JOURNAL 14/02/20 Does long‐term Bt rice planting pose risks to spider communities and their capacity to control planthoppers?
Genetically modified crops expressing insecticidal Cry proteins from Bacillus thuringiensis (Bt) have been grown commercially since 1996 and have successfully controlled target pests, reduced insecticide usage and increased yields.
A major concern is that Bt crops may trigger outbreaks of non‐target herbivores against which they are not effective, by reducing bio‐control services provided by natural enemies, as seen with broad‐spectrum insecticides. Large‐scale and multi‐trophic field studies with Bt cotton in China have demonstrated that reduction in insecticide use associated with the growing area of this crop was related to outbreaks of the non‐target pest, the mirid bug. PLANT BIOTECHNOLOGY JOURNAL 06/03/18 Bt rice could provide ecological resistance against nontarget planthoppers. Introduction Insect‐resistant genetically engineered (GE) plants expressing Cry proteins from the bacterium Bacillus thuringiensis (Bt) have been widely adopted worldwide; 98.5 million hectares were planted with Bt crops in 2016 (ISAAA, 2016).
Bt plants are efficient in controlling certain target insect pests (Carrière et al., 2003; Hutchison et al., 2010; National Academies of Sciences, Engineering, and Medicine, 2016; Wu et al., 2008) and can lead to a significant decrease in the application of the chemical insecticides which are often necessary in conventional cropping systems (Klümper and Qaim, 2014; National Academies of Sciences, Engineering, and Medicine, 2016). The replacement of such chemical insecticides by Bt crops can therefore benefit human health and the environment (Huang et al., 2005; Lu et al., 2012; Marvier et al., 2007; National Academies of Sciences, Engineering, and Medicine, 2016; Shelton et al., 2002).

PLANT SCI. 08/10/19 The Cost of Postponement of Bt Rice Commercialization in China. Introduction With only 6% of the world’s fresh water and 7% of its arable land, China has to nurture nearly a fifth of the world’s population (Wong and Chan, 2016).
The arable land per capita in China decreased from 0.11 ha in 1990 to 0.09 ha in 2016, well below the world average of 0.19 ha per capita (World Bank, 2017b). Although rice is the predominant staple food in the country, the land allocated to its production decreased from 33.1 million ha in 1990 to 30.7 million ha in 2017 [National Bureau of Statistics of China (NBSC), 2018]. On the other hand, the amount of imported rice increased from 0.6 million metric tons in 2011 to 4.0 million tons in 2017, making China the biggest rice importer in the world (NBSC, 2018). The United States (US) Census Bureau estimates that the Chinese population will reach 1.4 billion around 2026, which will further reduce the arable land per capita and increase the demand for rice.

In fact, among the biotic stresses, damage caused by insect pests, which can be categorized as either minor or major pests, can severely constrain the potential yield of rice. Hence, planting transgenic rice is considered a solution for reducing environmental and human health impacts. Therefore, in this research, life cycle assessment for environmental and human health impacts of transgenic and non-transgenic rice cultivars was considered.

By An Baijie A Beijing lawyer's request to sue the Ministry of Agriculture, in order to force it to release scientific data about genetically modified (GM) rice, was rejected by a local court. Wei Rujiu, 40, head of the Beijing Weirujiu Law Firm, told the Global Times Tuesday that he tried to file papers with Beijing No. 2 Intermediate People's Court on March 17 but the court turned him away.
He attempted to collect data about the experiments that were done to show GM rice would be safe for consumers. A court official surnamed Jiang confirmed Thursday to the Global Times that intermediate courts are not obligated to accept such lawsuits because the lawyer did not prove a direct relationship with the ministry. He suggested the lawyer apply to other relevant government departments for a solution, Jiang said, without naming the departments.
Wei said although he didn't have any direct relations with the ministry, GM rice poses potential harm to his health. The issue has divided the public. GMO FREE EUROPE 09/02/10 Bt brinjal approval key to progress in Indian GM rice trials. Mahyco in bio-safety research stage. M.R. Subramani Chennai, Feb. 7 The Government's decision whether to allow or not allow commercial cultivation of Bt brinjal holds the key for further trials in genetically modified (GM) rice. “Bt brinjal is the first product that has come up for approval. “At least, 25 separate trials are being held in GM rice. As the Government is holding public hearings on permitting commercial cultivation of Bt brinjal, the Genetic Engineering Approval Committee (GEAC) has put on hold permission for trials of genetically modified cereals, including corn.
Among the firms that are into GM rice trials are Bayer Bioscience, Avesthagen and Mahyco.
