Antifungal and antibacterial activities of lectin from the seeds of Archidendron jiringa Nielsen

► Many plants contain proteins that are usually referred to as lectins on the basis of their specific carbohydrate-binding properties. ► They were originally only isolated from plant extracts and were used for the agglutination of blood cells. ► Some of the lectins isolated from plants were found to exhibit different biological activities. ► This paper reports on the inhibitory effect of purified A. jiringa seed lectin against growth of plant-pathogenic bacteria and fungi.
