Integrated Dual-Channel Retrograde Signaling Directs Stress Responses by Degrading the HAT1/TPL/IMPalpha-9 Suppressor Complex and Activating CAMTA3

This study identifies MEcPP as a stress-induced metabolite that disrupts the HAT1/TPL/IMP-9 suppressor complex, releasing CAMTA3 and enabling Ca2+ influx to activate stress responses.

Transcript profiling of plastid ferrochelatase two mutants reveals that chloroplast singlet oxygen signals lead to global changes in RNA profiles and are mediated by Plant U-Box 4

This paper shows that chloroplast singlet oxygen signals in fc2 mutants alter global RNA profiles, induce stress responses, and are modulated by PUB4.

Mapping protein-metabolite interactions in E. coli by integrating chromatographic techniques and co-fractionation mass spectrometry.

The paper introduces PROMIS, a co-fractionation mass spectrometry technique integrated with chromatographic methods to map protein-metabolite interactions in E. coli, identifying 994 interactions and revealing novel functional insights.
