Simply put, as food demand increases due to population growth and increased affluence, crop yields are likely to decrease due to the changing climate. Plant scientists will be familiar with many research avenues that aim to address this disconnect, ranging from increasing crop resilience to abiotic stresses,…

Potassium is one of the major nutrients for plant growth and development. Plants have a well-studied potassium uptake system mediated by transporters and ion channels. Unfortunately, due to the chemical similarity of potassium and cesium, which is toxic for plant growth, cesium is able to to get into…

Legumes are important crops because they are protein-rich, as a consequence of symbiotic nitrogen fixation (SNF). In the past 20 years, through forward and reverse genetics more than 200 genes have been identified that are involved in this process, from recognition through nodule differentiation and…

Food security is a major issue in sub-Saharan Africa, aggravated by rapid population growth and low soil fertility. Stewart et al. explore approaches to improve soil fertility, hence food production, in this region. They argue for a holistic approach that addresses not only yields, but also poverty reduction…

Phosphorus (P) is an essential macronutrient for plant growth and development. P is predominantly absorbed by plants in its inorganic form, phosphate (Pi). Because Pi homeostasis is critical for balanced growth and development, plants like many other eukaryotic organisms have developed a complex system…

Nitrate is an important plant nutrient and multiple transporters have been identified in different plant species. NRT1.1 (NITRATE TRANSPORTER 1.1) belonging to the MFS (Major Facilitator Superfamily) has been shown to transport nitrate and auxin (IAA, Indole 3-acetic acid). This dual affinity transporter…

The symbiosis between plants and arbuscular mycorrhizal fungi is conditional. Plants that are limited for phosphate release strigolactones into the soil, promoting changes in the fungi that facilitate the symbiosis. Müller et al. found that a Medicago gene encoding a CLE peptide, MtCLE53, is induced…

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 …
