Bioimaging insights into structural pathways of cell-to-cell communication within the male (MGU) and female (FGU) germ units of Arabidopsis thaliana.

ABSTRACT:

Key message

Cytoplasmic connections are present between cells within male and female germ units (MGU, FGU), suggesting potential structural pathways for communication. Cell-to-cell communication within the male germ unit (MGU), which consists of two sperm cells and the vegetative cell nucleus, and the female germ unit (FGU), comprising the synergids, the egg cell, and the central cell, is crucial for gamete maturation, fertilization, and early embryogenesis in angiosperms. The MGU facilitates the transport and delivery of immotile sperm cells via the elongating pollen tube to the FGU/embryo sac, which is deeply embedded within the ovule and the ovary. Through applying various bioimaging techniques at both electron and light microscopy levels, we examine the structure and the functi
