By mediating iron uptake and sequestering processes in plastids, PIC1 is crucial for plant growth and development in general and in particular for fruit maturation.
Title: The chloroplast permease PIC1 regulates plant growth and development by directing homeostasis and transport of iron.

PIC1 functions in iron transport across the inner envelope of chloroplasts and hence in cellular metal homeostasis. [PIC1] [PERMEASE INCHLOROPLASTS1]
Title: PIC1, an ancient permease in Arabidopsis chloroplasts, mediates iron transport.

Tic21 functions as part of the inner membrane protein-conducting channel and may be more important for later stages of leaf development. [Tic21] [CIA5]
Title: Tic21 is an essential translocon component for protein translocation across the chloroplast inner envelope membrane.
