Abstract: Sucrose Synthase (SuSy),a key enzyme in sucrose metabolism, plays very role in both plant growth and developmental process. It is reported that SuSy gene is also closely relate to the ability of plant resistance to abiosmotic stress. In order to reveal the mechanism of SuSy gene in peanut, here, the TAIL-PCR technology of genome walking was used to obtain a genome sequence for the length of 6 189 bp,which included 13 exons, 12 introns and about an 825 bp length partial promoter region. Sequence analysis showed that typical elements as TATA-box, CAAT-box and some other regulate elements were contained in this region, such as cis-acting element involved in low temperature responsive element (LTR), GA responsive element,drought responsive of MYB hinging site, anae-robic induction element ARE and light responsive element G-box and box4 were found in the sequence. It was sup- posed that the expression of SuSy gene was induced by low temperature,drought,anaerobic and hormone GA etc.

Key words: Peanut, SuSy gene, Gene cloning, Promoter, Genome walking
