Annual Review of Plant Biology
Abstract
The size of seeds affects not only evolutionary fitness but also grain yield of crops. Understanding the mechanisms controlling seed size has become an important research field in plant science. Seed size is determined by the integrated signals of maternal and zygotic tissues, which control the coordinated growth of the embryo, endosperm, and seed coat. Recent advances have identified several signaling pathways that control seed size through maternal tissues, including or involving the ubiquitin-proteasome pathway, G-protein signaling, mitogen-activated protein kinase (MAPK) signaling, phytohormone perception and homeostasis, and some transcriptional regulators. Meanwhile, growth of the zygotic tissues is regulated in part by the HAIKU (IKU) pathway and phytohormones. This review provides a general overview of current findings in seed size control and discusses the emerging molecular mechanisms and regulatory networks found to be involved.
