Manganese deficiency affects root endodermal suberization and ion homeostasis (Plant Physiol.)

Manganese (Mn) is an essential plant nutrient necessary for multiple plant process such as photosynthesis. Mn deficiency has a significant impact on crop production particularly in cereals including barley (Hordeum vulgare L.). Chen et al. identified how Mn deficiency alters suberin deposition in the …

Opinion: Towards lowering crop N requirement (Plant Cell Environ)

Current and future food production demands a lot of nitrogen (N) fertilizers. Inefficient N fertilization leads to N losses to the environment and generates greenhouse gases that cause environmental problems. In a recent article, Swarbreck and colleagues discuss a strategy to develop crop varieties with…

Review: Imaging technologies to uncover the role of Ca2+ signaling in plant nutrient homeostasis (Plant Cell Environ)

Maintaining nutrient homeostasis is ridiculously challenging, in large part due to the tremendous effects individual nutrients have on other nutrients’ uptake and action, as well as the interactions between nutrient homeostasis and environmental conditions. In order to maintain the “right” amount…

SPX4 acts on PHR1-dependent and -independent regulation of shoot phosphorus status (Plant Physiol)

Plant phosphorus homeostasis is important to understand as humans seek to increase food production while also reducing the amount of agricultural inputs and environmental pollution. In their recent paper, Osorio and colleagues expand our current understanding of phosphorus homeostasis in Arabidopsis…

Review: Combinatorial nutrient stresses reveal emergent properties ($) (TIPS)

Plants require at least 14 mineral nutrients to complete their life cycle. These mineral nutrients are unevenly distributed within the soil, and plants have evolved physiological adaptations (changes in root growth, exudation, symbiotic relationships with soil organisms, etc.). to address these nutrient…

Nitrate–NRT1.1B–SPX4 cascade integrates N and P signaling networks (Nature Plants)

Plants need several mineral nutrients for their optimal growth and development. This is contingent on a proper nutrient balance particularly between the two most required essential elements, nitrogen (N) and phosphorus. Even though considerable success has been achieved in understanding the molecular…

Calcium-promoted interaction between EHB1 and IRT1 inhibits iron acquisition (Plant Phys)

Iron uptake is tightly controlled so that the plant takes up not too much but not too little. Khan et al. used a yeast two-hybrid screen to search for proteins that interact with the iron transporter IRT1. They identified a protein previously shown to be involved in the hypocotyl bending response, EHB1…

NRT1.1B is associated with root microbiota composition and nitrogen use in rice ($) (Nature Biotechnol)

Availability of nitrogen has always been a limiting factor for rice production. Different soil inhabitants and root-associated bacterial populations are involved in making nitrogen available to plants in organic as well as in inorganic forms. However, plant absorption of nitrogen is selective and affects…

Network paths for nitrogen response in Arabidopsis (Nature Comms)

A goal of systems biology is to study how transcription factors participate in gene regulatory networks (GRN) underlying biological processes. In a recent report, Brooks et al. used network science to uncover how transcription factors mediate the early response to nitrogen (N). Authors identified the…
