The invention belongs to the technical field of plant genetic engineering, and particularly relates to a gene for regulating and controlling the length of cotton fibers and application of the gene. The gene is a GhHD7 gene, the nucleotide sequence of the gene is as shown in SEQ ID NO.1, and the amino acid sequence of the encoded protein of the gene is as shown in SEQ ID NO.2. The expression quantity of the GhHD7 gene in the cotton is reduced by inserting or deleting the basic group of the GhHD7 gene in the cotton, and the fiber length of the obtained transgenic cotton plant is obviously shortened. The invention provides a favorable gene resource for cultivating high-quality cotton. 本发明属于植物基因工程技术领域，具体涉及一种调控棉花纤维长度的基因及其应用。该基因为GhHD7基因，其核苷酸序列如SEQ ID NO.1所示，其编码蛋白的氨基酸序列如SEQ ID NO.2所示。通过对棉花中GhHD7基因碱基的插入或缺失来实现棉花中GhHD7基因的表达量降低，得到的转基因棉花植株纤维长度显著变短。本发明为培育高品质棉花提供了有利的基因资源。
