Maize endosperm is the starchy tissue found within the seeds of maize (corn) plants. It is the primary storage tissue for nutrients such as starch, proteins, and lipids, and plays a crucial role in the development and germination of maize seeds. Research on maize endosperm focuses on understanding its molecular and cellular processes, such as starch synthesis and accumulation, protein storage, and nutrient transport. This research area is important for improving maize crop yield and quality, as well as for developing novel uses for maize endosperm in food and industrial applications.
