Abiotic

Abiotic factors are non-living chemical and physical elements in the environment, which affect individual organisms as well as ecosystems. Examples are UV, IR and visible light, radiation, temperature, wind, humidity, water, pH, heavy metals, atmospheric gases, soil chemicals, and, more generally, climate.

    Potassium (K+) is taken up by roots and redistributed within organs and organelles by a large number of channels and transporters. Export of K+ stored in vacuoles, required to support growth under limiting conditions, is mediated by the interaction of K+ channels with a calcium-dependent signalling network.

    The vacuole is a plant’s major phosphate (Pi) pool. Cellular Pi homeostasis highly depends on shuttling Pi between vacuoles and the cytosol. Glycerol 3-phosphate transporter types have now been identified as tonoplast-localized vacuolar Pi efflux transporters, integrating vacuolar Pi transport systems in plants.

    Hypoxia has long been studied in relation to anaerobic metabolism. It has now been shown to control development, acting as a cue to maintain the seedling's protective apical hook and a trigger of developmental decisions both before and after the plantlet emerges from the soil into the light.
