23 Jul Low-phosphorus inducible promoter and application thereof
Abstract
The invention provides a low-phosphorus inducible promoter and application thereof. The invention further provides a plant expression vector containing the promoter. The nucleotide sequence of the promoter is shown as the position 11862 of SEQ ID No:1, and the whole sequence contains 1862 basic groups. The promoter is mainly expressed at the root and is induced by low phosphorus. The promoter is applied to plant transgenic engineering. Specifically, the promoter can drive an exogenous gene to be expressed in plants, particularly can drive the exogenous gene to be expressed at the root of corninstead of in other tissue of the plants, and can improve the root character of the corn. Moreover, the promoter can be used for improving the survival and growth capacity of the corn under a low-phosphorus condition, so that an ideal corn variety can be cultivated.
