HD-Zip belongs to homeobox protein family and consists of homeodomain and additional leucine zipper domain, which is an important TF in plants. HD-Zip TFs in plants can be divided into four categories (HD-Zip I, HD-Zip II, HD-Zip III, and HD-Zip IV). HD-Zip I mainly responds to external signals, such as extreme temperature, drought and osmotic pressure in abiotic stress; and regulates plant growth to adapt to the environment. HD-Zip II is mainly involved in light stress response and auxin signal transduction. HD-Zip III is involved in the regulation of plant growth and development, such as meristematic formation, lateral organogenesis, polar auxin transport, and vascular system development. HD-Zip IV lacks the MEKHLA structure relative to the HD-Zip III subclass and is mainly involved in root development, plant cell differentiation, trichome formation and anthocyanin accumulation. We identified 84 HD-ZIP genes, including JTY(27), LWM(28) and F106(29) , all genes were divided into 4 subfamilies.
