Plant roots explore the soil environment in search for water and nutrients required for growth. Multiple physiological and genetic studies have provided ample evidence in support of the role of plant hormones in root growth and development. Among them, ethylene is a simple gas phytohormone and its regulation of root growth has been extensively studied. This review summarizes the molecular regulation of root development by ethylene. Through use of genetic screening, high‐throughput nucleotide sequencing techniques, and CRISPR‐Cas9 technology, many potential genes involved in ethylene‐regulated root growth are discovered. Thus, this review provides an overview of ethylene in root growth, which provides guidance for crop breeding to engineer better crop varieties of root architectures.
