RESUMO

Double-stranded soybean leghemoglobin DNA was synthesized from leghemoglobin mRNA isolated from soybean nodules. The dsDNA was inserted into the Bam H1 site of plasmid pBR322 using the poly-dAT-joiner method. A cloned DNA fragment of one recombinant plasmid was isolated and characterized by restriction endonuclease digestion. The restriction cleavage map and the DNA sequence of a selected part of the inserted DNA are in complete accordance with the amino-acid sequence of soybean leghemoglobin.
