| abstract |
The invention provides a plant endosperm specificity expression promoter pENP2 and application thereof, and an expression cassette, recombinant expression vector, host bacterium and transformant containing the promoter. The invention also provides application of the promoter in transgenic engineering of plants. The promoter provided by the invention can promote specificity expression of an exogenous gene in plant endosperm, and is applicable to plants having endospermous seeds, especially monocotyledons or endospermous dicotyledons; and especially, the promoter can drive the exogenous gene to perform specificity expression in rice endosperm. Thus, the promoter can be used for increasing and improving the quality of rice, thereby cultivating ideal rice with higher quality. |
