Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction
Advanced Science, EarlyView.During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Restoring Iron Homeostasis via Smoothened Inhibition: A Novel Strategy Against Hearing Loss
Advanced Science, EarlyView.. ABSTRACT Sensorineural hearing loss (SNHL) induced by noise or aminoglycoside antibiotics is a significant public health concern without any FDA‐approved pharmaceutical therapies. Dysregulation of iron homeostasis and its subsequently induced ferroptosis has increasingly been identified as a key mechanism underlying cochlear hair cell (HC) damage ...

Predicting and Rationalizing Piezoelectricity in Racemic Bioorganic Molecular Crystals
Angewandte Chemie, EarlyView.Racemic molecular crystals, composed of equal mixtures of chiral enantiomeric components, are predicted to exhibit significant piezoelectric responses and favourable mechanical flexibility. This study identifies organic and bioorganic racemates as promising candidates for sustainable, lead‐free materials, enabling next‐generation applications in energy

Microbial sensors for L-aspartic acid and urea.
BUNSEKI KAGAKU, 1990 アスパラギン酸センサーは,L-アスパラギン酸β-デカルボキシラーゼ活性をもつPseudomonas dacunhae をκ-カラギーナンで固定化した膜と二酸化炭素電極を組み合わせて作製した.このセンサーは0.2～5mMの濃度範囲で直線性を示し,安定性及び選択性も優れていた.このセンサーによる測定値は他の方法によるものとよい相関を示した.尿素センサーはウレアーゼ活性をもつSporosarcina ureae膜をP. 5ン粥膨伽卿欄6膜を君dacunhaeの場合と同じ方法で調製したものを,アンモニアガス電極に取り付けて作製した.このセンサーは0.1～50mMの範囲で直線性を示し,安定性及び選択性も優れていた.
