Method for improving resistance of plant to fusarium graminearum by utilizing gene AtALA1

The invention relates to a method for improving the resistance of a plant to fusarium graminearum. The method comprises the following steps of integrating a gene AtALA1 into the target plant, and expressing the gene AtALA1 in the target plant to reduce the toxin content of the fusarium graminearum so as to improve the resistance of the plant to the fusarium graminearum, wherein a nucleotide sequence of the gene AtALA1 is as shown in SEQ ID NO.14. According to the method, the toxin content in the plant body is obviously reduced and the resistance to the fusarium graminearum is improved by utilizing a transport degradation mechanism of the plant to toxins of pathogenic bacteria. Therefore, the method can be widely used for improving the resistance of different pathogenic bacteria and toxinsthereof, and has wide applicability. 本发明涉及一种提高植物对禾谷镰刀菌的抗性的方法，其中通过将AtALA1基因整合进入目标植物，并使得所述AtALA1基因在目标植物中表达而降低禾谷镰刀菌毒素含量，提高植物对禾谷镰刀菌的抗性，所述AtALA1基因的核苷酸序列如SEQ ID NO.14所示。本发明利用植物对病原菌毒素的转运降解机制，显著降低植物体中的毒素含量，同时提高了对禾谷镰刀菌的抗性。因此，可以广泛应用于提高
