Beschreibung
Zusammenfassung:	The invention provides a sweet potato drought resistance related gene ItbRASD1 and application thereof, and belongs to the technical field of plant genetic engineering. According to the invention, the excellent drought-resistant gene ItbRASD1 is obtained by amplification from sweet potato related wild species, and the nucleotide sequence of the gene is as shown in SEQ ID NO: 1. Subcellular localization and promoter activity of the gene are researched, sweet potatoes are subjected to overexpression genetic transformation, and the drought resistance of the sweet potatoes is improved. The invention provides help for further understanding the drought resistance mechanism of sweet potatoes, and provides candidate genes for improving the drought resistance of sweet potatoes and creating new drought-resistant materials of sweet potatoes by using genetic engineering means. 本发明提供了一种甘薯抗旱相关基因ItbRASD1及其应用，属于植物基因工程技术领域。本发明从甘薯近缘野生种中扩增获得优良的抗旱基因ItbRASD1，所述基因的核苷酸序列如SEQ ID NO:1所示。本发明研究了该基因的亚细胞定位、启动子活性，并过表达遗传转化甘薯，提高了甘薯的抗旱性。本发明为
