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.

Cytosolic heme metabolism by alternative localization of heme oxygenase 1 in plant cells

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.

A novel sorting signal for RNA packaging into small extracellular vesicles

The paper identifies a novel RNA sorting signal in the 3UTR of RAB13 that selectively packages RNA into small extracellular vesicles.

Enhancer evolution as a driving force for lineage-specific paralog usage in the central nervous system.

The paper investigates how enhancer evolution drives lineage-specific paralog usage in hypophysiotropic GnRH neurons across vertebrates, finding that enhancer loss, not regulatory changes, caused paralog role division.

Biochemical reactions between intra-articular tissues and joint instability in a rat model of osteoarthritis

This study investigates the role of joint instability in osteoarthritis progression using a rat model, finding that joint instability exacerbates cartilage degeneration and that TGF-β1 inhibition may reduce synovial inflammation.

Comprehensive Analysis of Peptide-Coding Genes Identifies an LRR-only Microprotein That Regulates Reproductive Organs in Marchantia polymorpha

This study identifies an LRR-only microprotein, MpSGF10B, that regulates reproductive organ development in Marchantia polymorpha by affecting antheridiophore formation.

Stomatal regulators are co-opted for seta development in the astomatous liverwort Marchantia polymorpha

The paper shows that a Ia-IIIb bHLH TF module regulates seta development in liverwort Marchantia polymorpha, similar to its role in stomatal formation in stomatous plants.

A stepwise route to domesticate rice by controlling seed shattering and panicle shape

This study identifies multiple genetic mutations required for rice domestication, showing that seed shattering loss alone is insufficient and that panicle shape plays a critical role in yield increase.

T cell-intrinsic vitamin A metabolism and its signaling are targets for memory T cell-based cancer immunotherapy

This study identifies vitamin A metabolism and its signaling as regulators of memory T cell differentiation and shows their potential as targets for cancer immunotherapy.

Effect of differences in mechanical stress in vivo on the onset and progression of knee osteoarthritis

This study investigates how different types of mechanical stress affect knee osteoarthritis onset and progression using animal models.

Effect of Suppression of Rotational Joint Instability on Cartilage and Meniscus Degeneration in Mouse Osteoarthritis Model

This study compares the effects of two knee instability models on cartilage and meniscus degeneration in mice, finding that reducing rotational instability suppresses cartilage degeneration.
