Abstract: In silico cloning is developing with the project of genomic and EST. It is a new method of gene-cloning through bioinformatics. A query probe from the cDNA sequence of Arabidopsis thaliana pyridoxine biosynthesis protein was designed to blast Glycine max EST database according to the relative conservation of homologous genes and a soybean PDX gene cDNA of 1280 bp was obtained (GenBank Accession, DQ139265). This sequence was confirmed by RT-PCR, genomic PCR, molecular cloned and sequenced. It contained a complete ORF, from 20 to 955 bp, encoded 311 amino acids, and conserved with Arabidopsis thaliana, Oryza sativa, Lotus corniculatus var. japonicus, Nicotiana tabacum, Medicago truncatula and Triticum aestivum. The results showed that it was an efficient technique to clone new genes by searching EST database with homologous gene of model species.

Key words: In silico cloning, EST database, RT-PCR, Genomic PCR, Glycine max, Pyridoxine biosynthesis(protein)
