Straining the root on and off triggers local calcium signaling

This study applies lateral pressure to plant roots to investigate calcium signaling, finding that straining triggers localized calcium signals that attenuate with repeated stimulation.

Proton exchange in the nitrate vacuolar transporter AtCLCa is required for growth and nitrogen use efficiency

This study shows that the AtCLCa exchanger's proton exchange function is critical for plant growth and nitrogen use efficiency.

Manganese excess and deficiency affects photosynthesis and metabolism in Marchantia polymorpha

This study examines how manganese excess and deficiency impact photosynthesis and metabolism in the liverwort Marchantia polymorpha, revealing unique responses to metal stress.

Duplication of NRAMP3 gene in poplars generated two homologous transporters with distinct functions

This paper identifies two NRAMP3 paralogues in poplars with distinct functions: one retains vacuole metal release function, while the other localizes to the TGN and controls manganese cell-to-cell transport.

Copper microRNAs govern the formation of giant feeding cells induced by the root knot nematode Meloidogyne incognita in Arabidopsis thaliana

The paper identifies miR408 and miR398 as key microRNAs regulated by SPL7 that are upregulated in nematode-infected roots and essential for forming giant feeding cells.

Transduction of mechanical cellular oscillation by the plasma-membrane mechanosensitive channel MSL10

The paper shows that MSL10, a mechanosensitive channel in Arabidopsis, responds to mechanical oscillations with rapid activation and behaves as an oscillation follower in the 0.3-3 Hz range.

Dynamic measurement of cytosolic pH and uncovers the role of the vacuolar transporter AtCLCa in the control of cytosolic pH.

The paper uses a biosensor to measure cytosolic pH and anion dynamics in Arabidopsis, revealing that AtCLCa regulates cytosolic pH and nitrate levels.

Autophagy is essential for optimal Fe translocation to seeds in Arabidopsis

This study shows autophagy is necessary for efficient iron and other micronutrient translocation to seeds in Arabidopsis.

Wide cross-species RNA-Seq comparison reveals a highly conserved role for Ferroportins in nickel hyperaccumulation in plants

The paper identifies convergent functions in nickel hyperaccumulation across plant species, highlighting the conserved role of IREG/Ferroportin transporters.

Vacuolar iron stores gated by NRAMP3 and NRAMP4 are the primary source of iron in germinating seeds

The paper shows that NRAMP3 and NRAMP4 are essential for mobilizing vacuolar iron stores during seed germination, and their absence triggers Fe deficiency responses affecting plastids but not mitochondria.
