Review: Tackling plant phosphate starvation by the roots (Devel. Cell)

The root is remarkably responsive to nutrient status of both the local environment and the whole plant. These external and internal factors affect the expression of transporters, interactions with mycorrhizal symbionts and also the overall pattern of growth and development of the root system. In this…

Antagonistic responses to ‘symbiotic’ AM fungi in the non-host Arabidopsis thaliana ($) (New Phytol)

A strikingly vast array of phylogenetically distant plants are able to form intimate interactions with symbiotic arbuscular mycorrhizal (AM) fungi for the mutually beneficial exchange of nutrients. Several years of intensive research have revealed the complex regulatory networks and genetic ‘toolkits’…

Nitrogen actively controls phosphate starvation response in plants (Plant Cell) ($)

Phosphate and nitrogen are two essential macronutrients for growth of plants. The homeostasis and sensing pathways for these two macronutrients have been investigated extensively, but independently. Recently, -omics approaches have enabled finding interlinks and cross talks between two or more macronutrients.…

Independent regulation of symbiotic nodulation by the SUNN negative and CRA2 positive systemic pathways (Plant Physiol) ($)

Autoregulation of nodule development (AON) is a process by which leguminous plants control nodule development. SUNN, a LRR-RLK, and a systemic CLE peptide play a negative role in nodulation through systemic signaling. In this paper Laffont et al. showed the another systemic regulation of nodulation in…

Crystal structure of plant vacuolar transporter VIT1 (Nature Plants) ($)

Iron is an essential nutrient for plants that participates in cellular processes such as DNA replication, photosynthesis, and respiration. Excess iron accumulation is harmful to plants due to its participation in the generation of reactive oxygen species, which can damage cellular machinery. One of the…

Nitrate transporter gene OsNRT1.1A/ OsNPF6.3 confers high yield in rice (Plant Cell)

In many ecosystems, nitrogen (N) is a limiting factor for plant growth. In agro-ecosystems, the application of synthetic N fertiliser has solved that issue. However, N fertiliser application is costly both to the farmers and the environment (in terms of N leaching and atmospheric release of greenhouse…

Dancing with hormones: A current perspective of nitrate signaling and regulation in Arabidopsis (Frontiers in Plant Science)

Nitrogen (N) is a main constituent of amino acids and nucleotides and therefore plays a central role in plant growth, development, and stress responses. Plants are able to take up nitrogen from the soil in two forms, nitrate and ammonium. Nitrate is the predominant form of nitrogen found in most crop…

Food for thought: How nutrients regulate root system architecture (Current Opinion in Plant Biology)

The arrangement of a plant’s root system in the soil (root system architecture, RSA) changes in response to nutrients through different signaling pathways. It is assumed that RSA adapts to optimize the uptake of nutrients from the environment, but strong evidence is still lacking. This review by Shahzad…

Increased temperatures may safeguard the nutritional quality of crops under future elevated CO2 concentrations (Plant J)

Increases in atmospheric CO2 have been shown to confer enhanced photosynthetic rates, boosting plant growth and yield.  Unfortunately, there is evidence that the content of minerals important for human health are reduced in both the foliar and edible tissues when plants are grown under elevated CO2…
