The invention belongs to the technical field of gene engineering, and particularly relates to an oilseed rape BnaILR gene and application thereof in regulating and controlling the early maturing character of oilseed rape. The premature related gene BnaILR is screened through transcriptome sequencing analysis, and the expression quantity of the premature related gene BnaILR is remarkably related to the content of IAA and GA3. The construction of an overexpression and interference vector of the BnaILR gene proves that the BnaILR gene has a positive regulation effect on the growth and development of the rape: an overexpression strain shows a remarkably enhanced growth situation, and an interference strain grows slowly. The overexpression of the BnaILR leads to the down-regulation of the expression of the gene TAR2 and the up-regulation of the expression of the gene GH3.1 / GH3.2, and accords with an IAA level over-high feedback regulation mode, which indicates that the BnaILR plays a core role in regulating the capacity of an active IAA library and feeding back and regulating an IAA synthesis pathway, and subcellular localization analysis confirms that the BnaILR protein is localized in a cell nucleus, and reveals a molecular mechanism that the BnaILR influences growth and development by regulating the steady state of IAA.
