The Arabidopsis katamari2 Mutant Exhibits a Hypersensitive Seedling Arrest Response at the Phase Transition from Heterotrophic to Autotrophic Growth

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.

Transcriptional activation of auxin biosynthesis drives developmental reprogramming of differentiated cells

This study shows that activating auxin biosynthesis transcription is essential for reprogramming differentiated Arabidopsis leaf cells to pluripotency by reactivating the cell cycle.

Pyrophosphate modulates stress responses via SUMOylation

This study shows that pyrophosphate modulates stress responses by inhibiting SUMOylation, affecting cold and heat stress sensitivity in plants and yeast.
