摘      要：Recent breakthroughs in transcriptome analysis and gene characterization have provided valuable resources and information about the maize endosperm developmental *** high temporal-resolution transcriptome analysis has yielded unprecedented access to information about the genetic control of seed *** spatial transcriptome analysis using laser-capture microdissection has revealed the expression patterns of specific populations of genes in the four major endosperm compartments:the basal endosperm transfer layer(BETL),aleurone layer(AL),starchy endosperm(SE),and embryo-surrounding region(ESR).Although the overall picture of the transcriptional regulatory network of endosperm development remains fragmentary,there have been some exciting advances,such as the identification of OPAQUE11(O11)as a central hub of the maize endosperm regulatory network connecting endosperm development,nutrient metabolism,and stress responses,and the discovery that the endosperm adjacent to scutellum(EAS)serves as a dynamic interface for endosperm-embryo *** addition,several genes that function in BETL development,AL differentiation,and the endosperm cell cycle have been identified,such as ZmSWEET4c,Thk1,and Dek15,***,we focus on current advances in understanding the molecular factors involved in BETL,AL,SE,ESR,and EAS development,including the specific transcriptional regulatory networks that function in each compartment during endosperm development.
