Abstract: Using Arabidopsis thaliana pyridoxal kinase (PK) protein sequence as a query probe to blast Glycine max EST database,a soybean PKgene cDNA of 1 102 bp was obtained and cloned by RT2PCR and sequenced(GenBank Ac2 cession, DQ006813). The result confirmed that the in silico cloning cDNA sequence was accurate. It contains a complete open reading frame,from 119 bp to 1 045 bp, encodes 308 amino acids. Using semiquantitative RT2PCR,we found that PK gene was not regulated by illumination. It expressed in Glycine max leaves,stems and roots. The deduced amino acid sequence of Glycine max PKwas aligned against sequences from other species such as Solanum tuberosum, Arabidopsis thaliana, Oryza sativa, Triticum aestivum and Brassica napus. It showed the identity of 81 %,75 %,78 %,79 % and 76 %,respectively. The results revealed the Glycine max PKwas significant similarity in plants. Phylogenetic tree of plant PKs was mainly consistent with the classification system of these plants.

Key words: Glycine max, In silico cloning, Pyridoxal kinase
