Mitochondria and stress signalling

How does a plant sense stress and pass those signals around its body? Corentin Dourmap and colleagues have reviewed the role of...

Does Viagra really help preserve flowers?

It is said that sildenafil citrate can help preserve flowers. Here's an experiment that you could do at home, but probably shouldn't, to find out.

Scientists find critical receptor that allows plant cells to pass stress signals

Adenosine triphosphate (ATP) is well-known for its role in cells as acting almost like currency for energy storage. Research by Elsa Matthus...

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...

Cytosolic dehydrogenase in Arabidopsis responses to root-knot nematode infection

Plant defence reaction is associated with activation of primary metabolic pathways. Glucose-6-phosphate dehydrogenase (G6PDH), the key enzyme of the oxidative pentose phosphate (OPP), pathway...

Subsidiary cell formation in Poaceae stomatal complexes

Polarisation and asymmetrical division generating the Poaceous subsidiary cells constitutes a very attractive model for the study of local intercellular stimulation. Auxin operates as...

Non-Specific Phospholipase C2 (NPC2) in plant immune responses in Arabidopsis

The non-specific phospholipases C (NPC) are recently discovered new subclass of plant phospholipases. Most of them have not yet been characterised thoroughly. Krčková et al....

Modulation of host plant immunity by Tobamovirus proteins

To establish infections, plant viruses effect profound alterations to host physiology that disturb endogenous processes and contribute to the development of disease symptoms. Conti...

Elevating expression of phytoglobins enhances photosynthetic response of root-flooded maize

Decreased crop photosynthetic rates are a major consequence of root flooding as severe perturbations of the photosynthetic machinery result from elevated levels of reactive...

Regulation of peroxidase and molecular functions of 2-Cys PrxA

The 2-Cys peroxiredoxin (Prx) A protein of Arabidopsis thaliana performs the dual functions of a peroxidase and a molecular chaperone depending on its conformation...

X-ray dose limits for microscopy lower than we thought

Subtle damage to hydrated tissue occurs at a far lower dosage than previously thought, and may be difficult to recognize.

Habitat partitioning through reproductive interference in Geranium

We’re familiar with seeing insects flit from one flower to the next, carrying pollen as they do so. What happens when they...

Improving overyielding in legume-based mixtures

A major challenge when supporting the development of intercropping systems remains the design of efficient species mixtures. The ecological processes that sustain...

The Oaks of the North Are Unexpectedly Well-Defended

Normally you would expect plant defences to increase, the closer you get to the equator. This is where insect life is more...
