The gene ZmDof08, which underlies the yellow-green leaf mutant phenotype in maize, enhances the activity of key enzymes involved in C photosynthesis, leading to a significant improvement in photosynthetic efficiency. Improving the photosynthetic efficiency of maize to increase its yield has long been a key focus in global agricultural research. Maize possesses a rich resource of leaf color mutants, which serve as valuable materials for studying leaf photosynthesis.

The D1 subunit of photosystem II (PSII) is subject to light-induced damage. In plants, D1 photodamage activates translation of chloroplast mRNA encoding D1, providing D1 for PSII repair. Three D1 assembly factors have been implicated in the regulatory mechanism: HCF244 and RBD1 activate translation, whereas HCF136 represses translation in the dark.

Transition metals play essential roles as coenzymes and catalysts in plants and are vital for chloroplast function and photosynthetic efficiency. Nickel (Ni) and cobalt (Co) are two important trace transition metals that are present in chloroplasts. However, the functions of Ni and Co in maize and the mechanisms regulating their homeostasis in chloroplasts remain poorly understood.

Plastid division regulatory genes play a crucial role in the morphogenesis of chloroplasts and amyloplasts. Chloroplasts are the main sites for photosynthesis and metabolic reactions, while amyloplasts are the organelles responsible for forming and storing starch granules. The proper division of chloroplasts and amyloplasts is essential for plant growth and yield maintenance.

This study identifies the chloroplastic polypeptide chain release factor ZmcpRF1 as a key regulator of chloroplast development and leaf color in maize, affecting both plant survival and growth. Leaf color mutations are a visible phenotype in plants and provide valuable insights into photosynthesis and other biological processes. In this study, we focused on a maize mutant with the segregation of pale green and stunted phenotypes.
