Lectins are a group of proteins or glycoproteins with various potentially exploitable
bioactivities and have been capturing more interest recently. They have been isolated and reported
from various tissues of a diversity of plant species. Tubers are modified and enlarged
plant structures derived from stems or roots that are used for nutrient storage and asexual reproduction.
A number of plants such as yam, taro and potato are grown for their edible tubers,
and lectins are found to be one of the major storage proteins. These lectins exhibit potent bioactivities
encompassing mitogenic, antitumor, antimicrobial, immunomodulatory, antioxidative,
hypoglycemic, insecticidal and nematicidal activities. They are potential resources for
development into functional or healthy foods and targets for food protein researchers.
