The small iron-deficiency-induced protein OLIVIA and its relation to the bHLH transcription factor POPEYE

This study identifies OLIVIA as a small Fe deficiency-induced protein that interacts with the bHLH transcription factor POPEYE, influencing Fe homeostasis and leaf growth.

Constant-pH molecular dynamics simulations of closed and open states of a proton-gated ion channel

This paper uses constant-pH molecular dynamics simulations to study pH-mediated conformational changes in the GLIC ion channel, identifying pH-sensitive residues and state-dependent pKa shifts.

Small ARF-like 2 GTPase TITAN 5 is linked with the dynamic regulation of IRON-REGULATED TRANSPORTER 1

This study shows TTN5 interacts with IRT1 and affects root iron reductase activity, linking vesicular trafficking to iron acquisition in plants.

Characterization of the small Arabidopsis thaliana GTPase and ADP-ribosylation factor-like 2 protein TITAN5

This study characterizes the Arabidopsis thaliana GTPase TTN5, revealing its rapid nucleotide exchange, non-classical GTPase activity, and dynamic membrane association in endomembrane transport.

FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR (FIT) accumulates in homo- and heterodimeric complexes in dynamic and inducible nuclear condensates associated with speckle components

This study shows FIT forms inducible nuclear condensates via liquid-liquid phase separation, which are linked to active transcription factor complexes and gene expression.

The effector FEP3/IRON MAN1 modulates interaction between BRUTUS-LIKE1 and bHLH subgroup IVb and IVc proteins

A targeted yeast two-hybrid screen identified interactions between E3 ligases BTSL1/BTSL2, bHLH subgroup IVb/IVc transcription factors, and effector FEP3/IMA1, revealing FEP3/IMA1 inhibits BTSL1-mediated degradation of bHLH proteins during Fe deficiency.

Cytokinin-promoted secondary growth and nutrient storage in the perennial stem zone of Arabis alpina

This study identifies cytokinin-promoted secondary growth in the perennial stem zone of Arabis alpina, where nutrient storage occurs independently of vernalization.

Transcriptomic expression patterns of two contrasting lowland rice varieties reveal high iron stress tolerance

The paper compares transcriptomic responses of two lowland rice varieties, Lachit and Hacha, under iron excess stress, identifying gene expression patterns linked to iron tolerance.

Putative cis-regulatory elements predict iron deficiency responses in Arabidopsis roots

The paper identifies 100 putative cis-regulatory elements that predict Arabidopsis root responses to iron deficiency using computational analysis of genome and transcriptome data.
