Application of tomato HD-Zip transcription factor SlHZ07 in regulating tomato plant height

Abstract

The invention discloses application of a tomato HD-Zip transcription factor SlHZ07 in regulation and control of tomato plant height, and belongs to the technical field of plant genetic engineering and molecular breeding. The invention provides an SlHZ07 gene for regulating and controlling the plant height, the nucleotide sequence of the SlHZ07 gene is as shown in SEQ ID NO.1, and the expressed SlHZ07 protein belongs to a tomato HD-Zip transcription factor. Experimental results show that overexpression of the SlHZ07 gene in tomato plants can significantly increase the tomato plant height, and the SlHZ07 gene can be used for tomato plant height character directional genetic improvement and excellent germplasm cultivation. The new tomato germplasm is successfully created, an important experimental material is provided for subsequent research, a gene resource and a breeding parent are also provided for further tomato plant height regulation and control, and the development of the tomato breeding industry is promoted.
