Abstract

The nucleotide sequences of 280–360-bp domains of lectin genes from 20 legume species belonging to 17 genera have been determined. A computer analysis of the sequences has been performed with the LASERGENE package. Based on this analysis, we constructed the phylogenetic tree of the lectins, which reflects their phylogenetic and evolutionary relationships, and predicted the amino-acid sequences of the corresponding protein domains. Features of the structure of the hydrocarbon-binding lectin domains were elucidated in some species of legume genera from the temperate climatic zone. The domains were highly variable and contained the consensus sequence AspTrePheXxxAsxXxxXxxTrpAspProXxxXxxIns/DelArgHis bearing the bulk of amino acid replacements, insertions, and deletions. An association between legume groups (including species from different genera and tribes) symbiotic with the same rhizobium species and the similarity between the hydrocarbon-binding domains of lectins from these plants was found.
