This invention relates to the field of biotechnology, specifically to the application of bioproducts expressing the EsPTI15 gene to regulate tiller number. The nucleotide sequence of the EsPTI15 gene is shown in SEQ ID NO:1. This invention is the first to discover that, compared to wild-type *Leymus chinensis*, EsPTI1… 5 Overexpression of the EsPTI15 gene significantly increased the number of tillers in *Triticum aestivum*, confirming that overexpression of the EsPTI15 gene positively regulates tillering development. This finding not only enriches the molecular mechanism theory of plant tillering regulation but also demonstrates the potential of the EsPTI15 gene to increase the number of tillers, paving the way for subsequent gene manipulation to introduce EsPTI1. 5 The research and development of technologies that increase the number of tillers in forage plants and thus improve biomass has provided key theoretical support and genetic resources.
