Bt rice producing Cry1C protein does not have direct detrimental effects on the green lacewing Chrysoperla sinica Tjeder
The effects of insect‐resistant genetically engineered rice producing Cry1C protein derived from Bacillus thuringiensis (Bt) on Chrysoperla sinica Tjeder (Neuroptera: Chrysopidae) were assessed in laboratory bioassays. Survival and development of C. sinica larvae were not adversely affected when the larvae were fed a diet containing purified Cry1C protein at 200 µg/g fresh weight of diet, ...

Effect of straw leachates from Cry1Ca‐expressing transgenic rice on the growth of Chlorella pyrenoidosa
Because of the prevalence of algae in rice paddy fields, they will be exposed to Bacillus thurigiensis (Bt) proteins released from Bt protein‐expressing genetically engineered rice. To assess the effects of leachates extracted from Cry1Ca‐expressing transgenic rice (T1C‐19) straw on the microalga Chlorella pyrenoidosa, we added purified Cry1Ca (10, 100, 1000 µg/L) and five concentrations of ...

Enhancement of salt tolerance in transgenic rice expressing an Escherichia coli catalase gene, kat E
Rice (Oryza sativa) is sensitive to salt stresses and cannot survive under low salt conditions, such as 50 mM NaCl. In an attempt to improve salt tolerance of rice, we introduced katE, a catalase gene of Escherichia coli, into japonica rice cultivar, Nipponbare. The resultant transgenic rice plants constitutively expressing katE were able to grow for more than 14 days in the presence of 250 mM ...
