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.

ZmPILS6 is an auxin efflux carrier required for maize root morphogenesis

This study identifies ZmPILS6 as an auxin efflux carrier in maize that regulates root morphogenesis by controlling auxin distribution and hormone signaling pathways.

Dosage differences in 12-OXOPHYTODIENOATE REDUCTASE genes modulate wheat primary root growth

This study identifies OPRIII genes in wheat that modulate root architecture and grain yield under water stress through jasmonic acid signaling.

A plastidial retrograde-signal potentiates biosynthesis of systemic stress response activators

The paper identifies MEcPP as a plastidial retrograde signal that initiates a cascade leading to the biosynthesis of systemic stress response activators in response to biotic and abiotic stresses.

ORA47 is a transcriptional regulator of a general stress response hub

The paper identifies ORA47 as a transcriptional regulator involved in the general stress response by interacting with the RSRE motif and functioning with CAMTA3 and JAZ1.

Reciprocity between retrograde signal and putative metalloprotease reconfigures plastidial metabolism and structure

The paper shows that the retrograde signal MEcPP increases VIR3 abundance, reducing target enzymes and altering plastid metabolism and structure under stress.

CamelliA-based simultaneous imaging of Ca2+ dynamics in subcellular compartments

A toolset for simultaneous imaging of Ca2+ dynamics in subcellular compartments has uncovered unrecognized Ca2+ signatures in Arabidopsis cells in response to developmental and external cues.

Retrograde induction of phyB orchestrates ethylene-auxin hierarchy to regulate growth

The paper shows MEcPP coordinates auxin and ethylene signaling via phytochrome B to regulate hypocotyl growth in response to light.

DHH1/DDX6-like RNA helicases maintain ephemeral half-lives of stress-response mRNAs associated with innate immunity and growth inhibition

This study shows that DHH1/DDX6-like RNA helicases in Arabidopsis thaliana regulate the stability of stress-response mRNAs involved in innate immunity and growth inhibition.
