ABSTRACT
The aim of this work was to study the cloning and characterization of HMW-GS 1Dx2 promoter from Triticum aestivum. A 1050 bp partial promoter fragment including a putative TATA box and 5' encoding sequence of the gene was cloned by amplifying the upstream sequences using the nest-PCR with appropriate primers. The analysis of the promoter sequence against the PLACE (Plant cis-acting Regulatory DNA Elements) database showed the presence of certain putative endosperm-specific regulatory cis-elements in the sequence along with the TATA and CAAT boxes. The histochemical method detected the transient expressions of GUS in the seeds of wheat. The results showed that HMW-GS 1Dx2 promoter had the endosperm-specific transcription activity in the wheat seeds.
