Abstract

The invention discloses a plant gene promoter and the application. It is has one nucleotide sequence from: the DNA sequence in SEQ ID No: 1; nucleotide sequence of DNA sequence intercross limited in SEQ ID No: 1; the nucleotide sequence has transcription initiation function and has 90% homology of the nucleotide sequence limited by SEQ ID No: 1. The tobacco transgene examination proves theat pGhGlcat1 could endue report gene having high level expression in epidermal hair, top meristem region and androecium and gynoecia of plant flower apparatus. It could be used to improve the plant quality and the gene engineer of fastness.

Description

technical field

[0001] The present invention relates to a plant gene promoter and its application, in particular to a plant gene promoter derived from cotton and its application in plant quality improvement. Background technique

[0002] Glycosyltransferases (GTs) catalyze the attachment of sugar groups to different acceptor molecules. Based on their sequence similarity, catalytic specificity, conserved sequence and donor sugar species, these enzymes are divided into different families ( T.Vogt, P.Jones, Glycosyltransferases in plant natural products synthesis: characterization of a supergene family, Trends Plant Sci.5(2000) 380-386; W.G.T.Willats, L.McCartney, W.Mackie, J.P.Knox, Pectin: cellbiology and prospects for functional analysis. Plant Mol. Biol. 47(2001) 9-27.). In plants, glycosyltransferases can convert the products of photosynthesis into disaccharides, oligosaccharides, polysaccharides and other small sugar molecules, so they play an important role in the devel...
