This study introduces regioselective bacterial heme oxygenases into Arabidopsis hy1-1 to test the retrograde heme signaling hypothesis, showing differential complementation of phenotypes related to phytochrome assembly and heme signaling.

This study shows that RLF, a heme-binding protein, is essential for organ development in Marchantia polymorpha and is evolutionarily conserved with a role in Arabidopsis thaliana.

This study identifies GUN1's molecular function as RNA binding and maturation by analyzing plastid transcriptomes and validating targets through RNA immunoprecipitation.

The paper identifies two HO1 transcripts in Arabidopsis and rice with distinct subcellular localizations and shows that cytosolic heme metabolism occurs during etiolation and early development.

This study identifies GUN1's role in chloroplast-to-nucleus retrograde signaling by showing it binds heme, affects tetrapyrrole biosynthesis, and enhances FC1 activity.
