The mysterious dialogue between the embryo, endosperm, and seed coat, and its implications for seed traits.
Figueiredo DD, Sharma RA
Plant Signaling
Signals that seeds send each other during development determine the size of the grains, beans, and fruits you eat — cracking this code could lead to crops that produce larger, more nutritious harvests.
Every seed is actually three different living structures working together: the baby plant, a nutrient-packed tissue that feeds it, and a protective outer coat. These three parts talk to each other using chemical signals to coordinate their growth — if communication breaks down, the seed fails. Scientists are now working out exactly how these conversations happen, which could let us engineer crops that grow bigger, more reliably.
Key Findings
Seeds contain three genetically distinct structures — embryo, endosperm, and seed coat — that must actively coordinate development for a viable seed to form.
Signaling mechanisms between seed tissues vary across plant species, suggesting diverse evolutionary strategies for seed development.
These inter-tissue communication pathways directly influence agronomic traits such as seed size, with implications for crop yield improvement.
chevron_right Technical Summary
Seeds are built from three distinct parts that must constantly communicate to develop properly. Scientists are mapping these hidden conversations, which control not just whether a seed survives, but how big it grows — a trait directly tied to crop yields.

The seeds of flowering plants contain three genetically distinct structures: the embryo, which will form a new plant; the endosperm, which nourishes the embryo; and the seed coat, which protects th...
