Lectins are a diverse group of proteins that bind specific carbohydrates and are found throughout all kingdoms. In plants, lectins are involved in a range of important processes such as plant defense and stress signaling. Although the genome sequence of Glycine max (soybean) has been published, little is known about the abundance and expansion patterns of lectin genes in soybean. Using BLAST and hidden Markov models, a total of 359 putative lectin genes have been identified. Furthermore, these sequences could be classified in nine of the twelve plant lectin families identified today. Analysis of the domain organization demonstrated that most of the identified lectin genes encode chimerolectins, consisting of one or multiple lectin domains combined with other known protein domains. Both tandem and segmental duplication events have contributed to the expansion of the lectin gene family. These data provide a detailed understanding of the domain architecture and molecular evolution of the lectin gene family in soybean. View Full-Text
