Salicylic acid-independent responses in PI4K mutants
Arabidopsis thaliana is the lab rat of plant sciences. Mutants tweaked in certain genes can show the effects of hormones on plants, but it can be hard to change one response without changing some others. How do plants...

Functional and chemical characterization of XAF
Plants rely on stiff cells walls for support. But these same cell walls have to be flexible to grow when required. Nguyen-Phan and Fry examine a chemical that regulates how this happens. Plant cell walls have many...

Nitrate nutrition improves energy efficiency under hypoxic stress
Plants take up and assimilate nitrogen (N) in the form of nitrate (NO3–) or ammonium (NH4+), or a combination of both. When oxygen availability is reduced (hypoxia), plants need to generate energy to survive and...

Characterization of a CONSTANS-Like gene induced in spaceflight
The complex networks and signalling pathways that equip plants to cope with environmental challenges in terrestrial environments developed over evolutionary time. Exposing plants to novel environments presents...
Calcium signaling regulates the protein VIP1 in touch responses in Arabidopsis
How can plants perceive mechanical stress such as touch? Calcium and several proteins are known to be involved, but it is still unclear how they interact. VIP1 of the model plant Arabidopsis thaliana is a bZIP (basic...
COI1-dependent growth, proteomic and metabolomic changes
Plant cell suspensions provide a model to study the apoplast and to monitor metabolic and cell cycle-related changes. Bömer et al. frame a case study for the stable transformation of Arabidopsis cell cultures...
Adaptation of ecological strategies to climate within species
In Grime’s C-S-R strategy model, plant ecological strategies vary between ruderals (R), stress-tolerators (S) and competitors (C). These variations are assumed to reflect adaptation of species to the environment...
Root hair abundance impacts cadmium accumulation in Arabidopsis thaliana shoots
Root hairs increase the contact area of roots with soil and thereby enhance the capacity for solute uptake. The strict hair/non-hair pattern of Arabidopsis thaliana can change with nutrient deficiency or exposure to...
Actin cytoskeleton, plant growth and development in Arabidopsis root hair mutant der1-3
The DER1 (deformed root hairs1) locus encodes a major vegetative actin (ACTIN2) in Arabidopsis thaliana. Mutations in DER1 lead to impaired root hair development. However, the role of this gene in overall plant...
Methanol-induced cell signalling processes
Methanol is a frequently used solvent, and a volatile organic compound (VOC) released from plant cell walls through the action of pectin methylesterases. Tran et al. show that cell wall-produced methanol is a signal in...
ARP2/3 complex links cell wall assembly and auxin distribution
The protein complex ARP2/3 is responsible for nucleating actin, and its loss results in multiple defects in young seedlings of Arabidopsis thaliana. Sahi et al. show that plants lacking the ARP2/3 complex have defects...
Quantifying temporal change in plant population attributes: insights from a resurrection approach
Plant populations vary over time as a result of the effects of environmental variation on life-cycle traits and genetic diversity. It is important to quantify how much populations actually change over time to better...
Effects of nitrogen and phosphorus supply on stoichiometry of six elements in leaves of Arabidopsis thaliana
Plant elemental composition is of fundamental importance for plant growth and metabolic functions. However, knowledge of how multi-elemental stoichiometry responds to varying nitrogen (N) and phosphorus (P)...
