23 Jul Reproductive organ and glandular hair tissue specific promoter GhS and application thereof
Abstract
The invention belongs to the field of plant gene engineering and discloses a reproductive organ and glandular hair tissue specific promoter GhS and the application of the promoter. The promoter is specifically express in arabidopsis thaliana anthers and stigmatoid tissues, petals, sepal glandular hair, leaf glandular hair, seed funiculi and epidermal hair of part of seeds. A nucleotide sequence ofthe promoter GhS is shown as SEQ ID NO. (sequence identifier number) 1. The promoter GhS has the following characteristics: A, an expression situation in an arabidopsis thaliana tissue is very clear;the expression of the promoter on plants such as cotton is not reported; B, the sequence of the promoter is from a cotton ovule; the specific expression of the promoter in the arabidopsis thaliana glandular hair implies that the promoter can specifically regulate the expression of a target gene in cotton fibers; and C, the promoter is novel in structure and has no homology with other promoters reported on a nucleic acid level; and homology sites do not contain the existing patent protected sequences and mutant sites.
