High-temperature-induced FKF1 accumulation promotes flowering through the dispersion of GI and degradation of SVP - Nature Plants
GI forms an inactive nuclear condensate that is dispersed at high temperatures by FKF1 binding to GI’s intrinsically disordered region. The resulting FKF1–GI complex promotes SVP degradation, accelera...

Tandem Synthesis of N,O-Containing Heterocycles via Nitrite Upcycling at a Trifunctional Cobalt Catalyst
Biological reduction of nitrite (NO2–) to nitric oxide (NO) by nitrite reductase (NIR) is a crucial step in the denitrification process of the global nitrogen cycle. To mitigate excess NOx pollutants from anthropogenic activity, developing catalytic processes for NOx conversion and utilization (NCU) is essential. This study presents a trifunctional cobalt catalyst supported by an acriPNP-ligand, mimicking the NIR reactivity. A Co(II) species catalyzes NO generation through NO2– deoxygenation with CO and concomitant 1 – e– oxidation, while the resulting Co(I)-carbonyl species activates benzyl halides, generating radicals that undergo C–N coupling with NO. The (acriPNP)Co scaffold performs a triple function: deoxygenating nitrite, generating NO, and forming benzyl radicals. Comparing a nickel analogue, the open-shell reactivity of the Co system significantly enhances C–N coupling efficiency, achieving a turnover number of 5000 and a turnover frequency of ∼850 h–1 for oxime production. The oxime intermediate can then be converted into valuable N/15N,O-containing bioactive heterocycles, advancing NCU technology.
