In germinating monocot seeds, scutella function in absorbing nutrients from the endosperm, transfer of sugars and amino acids to the developing plant and providing oil reserves. This critical role as a nutrient link also makes the scutellum prone to pest and pathogen attack. Grain crop scutella have long served as a model for lipid body and gibberellin (GA) phytohormone formation during seed development and germination. However, a role of the scutellum as a source of defense metabolites for protecting valuable nutrient reserves has been widely overlooked. Here, we highlight recent insights into the specialized metabolism with potential defensive functions in cereal scutella.
