Implication

Literature review reveals molecular networks coordinating maternal and zygotic signaling in plants, highlighting key targets for improving crop grain yield.

Key Points

To review the molecular mechanisms and integrated regulatory networks governing maternal and zygotic tissue interactions that determine seed size in plants.
Synthesized molecular and genetic findings on signaling cascades that regulate seed size across maternal and zygotic seed components.
Evaluated the roles of protein degradation, hormonal homeostasis, and transcriptional networks in coordinating embryo, endosperm, and seed coat growth.
Maternal tissues regulate seed size via the ubiquitin-proteasome pathway, G-protein signaling, mitogen-activated protein kinase (MAPK) cascades, phytohormone homeostasis, and specific transcriptional regulators.
Zygotic tissues coordinate seed growth through the HAIKU (IKU) pathway interacting with phytohormone signaling systems.
