NRT1.1 involved in balance between NH4+ uptake and assimilation ($) (Plant Physiol)
Plant Science Research WeeklyAmmonium (NH4+) is an inorganic nitrogen source that is the preferred source for some plant species (e.g., rice and tea) but can be toxic in high amounts. The nitrate transporter NRT1.1 is involved in mediating the effects of toxic NH4+, as well as functioning in NO3- and auxin transport, NO3- signaling…
Systemic upregulation of Zn partitioning to the shoot supplements local Zn-deficiency responses (Plant Cell)
Plant Science Research WeeklyZinc is an important micronutrient for plants and people. To better understand Zn uptake and homeostasis, Sinclair et al. used a transcriptomic approach to identify genes abnormally expressed in zinc-transporter mutants (hma2 hma4). In these mutants, Zn accumulates in roots but isn’t effectively transported…
Don’t Go Grocery Shopping When Hungry! Systemic Signaling in Zinc Homeostasis
The Plant Cell, The Plant Cell: In BriefGoing grocery-shopping on an empty stomach is a bad idea. You’re bound to make poor decisions, not based on nutritional content of the food but based on temporary cravings that will leave you asking for more later. Plants face this nutritional puzzle every day, since they eat where they shop, and shop…
Review: X-ray fluorescence microscopy imaging (Plant Physiol.)
Plant Science Research WeeklyKopittke et al. review the use of synchrotron-based X-ray fluorescence microscopy as a tool to quantify and localize diverse elements in plants. The authors describe how this method can be used to study nutrients in plants and human foods, as well as metal hyperaccumulating plants, and toxic metal(oid)…
trans-Zeatin in Shoots Drives Nitrate Systemic Signaling
Research, The Plant Cell, The Plant Cell: In a NutshellPoitout et al. study how plants forage for nutrients in the soil https://doi.org/10.1105/tpc.18.00011.
By Arthur Poitout and Sandrine Ruffel
Background: Nitrate, NO3- (the preferential nitrogen [N] source for most of higher plants) is spread unevenly in the soil due to its high mobile property,…
Maintaining Cellular Phosphate
Research, The Plant Cell, The Plant Cell: In a NutshellSegami et al. investigate cellular phosphate homeostasis in Arabidopsis. Plant Cell https://doi.org/10.1105/tpc.17.00911
Background: Many biological reactions, including the biosynthesis of DNA, RNA, proteins, and polysaccharides, produce inorganic pyrophosphate (PPi). However, accumulation of PPi…
Phosphate Translocation from Roots to Shoots is Precisely Modulated
Research, The Plant Cell, The Plant Cell: In a NutshellYe et al. discover a protein that mediates phosphate translocation and is dependent on environmental phosphate supply. Plant Cell (2018). https://doi.org/10.1105/tpc.17.00845
By Qing Ye and Yi-Fang Chen
Background: Phosphorus is a major essential nutrient for plant growth and development, and phosphate…
A Brake For Nitrogen Starvation Responses
Research, The Plant Cell, The Plant Cell: In a NutshellKiba et al. focus on transcriptional regulation of nitrogen starvation responses. Plant Cell https://doi.org/10.1105/tpc.17.00810
By Takatoshi Kiba
Background: Nitrogen availability in the soil profoundly affects plant growth and productivity, and thus crop yield. To meet expanding food demands,…
