This review uniquely integrates insights from QTL mapping, genome-wide association studies (GWAS), and transcriptome analyses across multiple crops to provide a holistic understanding of tiller development, a critical factor for crop yield enhancement. By highlighting key genetic loci, regulatory pathways, and gene candidates involved in tillering across wheat, maize, rice, and sugarcane, this work advances the field's knowledge of the genetic and molecular mechanisms that influence tillering. This multi-omics approach not only identifies significant genetic targets, such as TaMAX1, ZmTB1, and SoMAX genes, but also offers a foundation for innovative breeding and genetic engineering strategies aimed at increasing yield potential through optimized tillering traits.
