Sulphur deficiency leads to delayed senescence in barley
Deficiency led to reduction of proteases and nitrogen mobilization in senescing leaves.

The development of Ramularia leaf spot disease in barley
The fungus Ramularia collo-cygni (Ascomycotina) has recently become an important pathogen of barley (Hordeum vulgare), causing leaf spotting on upper leaves. McGrann and Brown studied the factors that cause this fungus...

Melatonin and its relationship to plant hormones
Plant melatonin appears to be a multi-regulatory molecule, similar to those observed in animals, with many specific functions in plant physiology.
Different types of rice tiller responses to nitrogen
Tillering is an important agronomic trait for rice population quality and grain production. In a recent study published in AoB PLANTS, Wang et al. found that nitrogen fertilizer application increased the number of rice...

Intra-specific variation in Arabidopsis functional strategies
Considerable intra-specific variation in functional strategies can occur within a single plant species. C-S-R theory was developed to classify functional strategies (competitive, stress tolerant, ruderal) in different...
Vitamin E, phosphorus availability and longevity in arabidopsis
Vitamin E helps to control the cellular redox state by reacting with singlet oxygen and preventing the propagation of lipid peroxidation in thylakoid membranes. Both plant ageing and phosphorus deficiency can trigger...
Redox markers for drought-induced nodule senescence in soybean
Marquez-Garcia et al. study the effects of drought in leaves and nodules of soybean (Glycine max) and find that while the physiological impact is perceived throughout the shoot, stress-induced senescence occurs only in...

Simulating nitrogen economy of wheat plants
The model NEMA (Nitrogen Economy Model within plant Architecture) simulates nitrogen fluxes within a wheat plant (Triticum aestivum) after flowering. Bertheloot et al. show that the model is able to predict the time...
Process-based model of N uptake and use in wheat
Defining strategies for better use of nitrogen by crops requires sufficiently mechanistic models of nitrogen acquisition and use by plants. Bertheloot et al. describe the model NEMA (Nitrogen Economy Model within plant...
