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 shows that Arabidopsis seedlings, including the katamari2 mutant, exhibit a growth arrest response during the phase transition from heterotrophic to autotrophic growth, which is an adaptive stress response rather than a carbon source deficiency.
