The invention belongs to the technical field of plant genetic engineering, in particular to a soybean gene promoter pEIF1 and pEIF1‑I Application in soybean, Arabidopsis and tobacco. The present invention clones the gene from soybean RPS28 and genes EIF1 ; Get the promoter by CTAB method pEIF1 and promoter pEIF1‑I , and then construct a soybean stable transformation vector, and realize pEIF1 and pEIF1‑I The expression of the driven GUS protein at each stage of soybean genetic transformation, found that pEIF1 , pEIF1‑I The driven GUS is expressed in cotyledons, radicles, germs, true leaves, compound leaves, buds, petioles, internodes, roots and nodules, indicating that pEIF1 and pEIF1- I It is a ubiquitous expression promoter, and the activity of GUS protein expression product in soybean is determined. In addition, it also implements pEIF1 and pEIF1‑I Driving transformation of GUS proteins in Arabidopsis and tobacco transformation.
