摘要: Here we describe development of transgenic elite rice lines expressing a Bt fusion gene derived from cryIA(b) and cryIA(c) under the control actinI promoter. The used in study were indica CMS restorer line Minghui 63 its hybrid Shanyou 63. level protein CryIA(b)/CryIA(c) detected (T51-1) plants was 20 ng/mg soluble protein. field-tested natural repeated heavy manual infestation two lepidopteran insects, leaffolder yellow stem borer. showed high protection against both insect pests without reduced yield.
