Abstract

Abstract: Plant seed size is a core determinant of crop yield,and its development is coordinately regulated by genetic information from both maternal and zygotic tissues. To date,several core pathways have been identified,including ubiquitin-proteasome,MAPK（mitogen-activated protein kinase） signaling,transcription factor regulatory pathway,G（guanosine triphosphate） protein signaling,IKU,and plant hormone. This paper reviews the research progress on molecular regulatory pathways of seed size in model plants such as Arabidopsis thaliana and Oryza sativa,elaborates on the functions,action mechanisms,and pathway interactions of key factors in the two major categories of regulatory pathways：maternal and zygotic tissues,and discusses the future research directions of molecular pathways of plant seed size,aiming to provide new insights for further refining the molecular mechanisms of seed size regulation.

Key words: Seed size, Maternal tissue, Zygotic tissue, Regulatory pathway
