Root-based N,-fixing symbioses: Legumes, actinorhizal plants, , sp. and cycads,reat diversity in many aspects of these root-based N2-fixing symbioses. Each symbiosis can be admired for the elegant means by which the host plant and microsymbiont integrate to form the mutualistic relationships so important to the functioning of the biosphere.

Cluster roots: A curiosity in context,n. Cluster-root forming species are generally non-mycorrhizal, and rely upon their specialised roots for the acquisition of phosphorus and other scarcely available nutrients. Phosphorus is a key plant nutrient for altering cluster-root formation, but their formation is also influenced by N and Fe. T

The physiology, genetics and molecular biology of plant aluminum resistance and toxicity,internal detoxification of Al with carboxylate ligands (deprotonated organic acids) and the sequestration of the Al-carboxylate complexes in the vacuole. This is a field that is entering a phase of new discovery, as researchers are on the verge of identifying some of the genes that contribute to Al

,Acclimation to soil flooding — sensing and signal-transduction,ion have received most attention. Aerenchyma formation, to promote gas diffusion through the roots, seems largely under control of ethylene, whereas adventitious root development appears to be induced by an interaction between ethylene and auxin. Parts of these pathways have been described for a ran

Facilitative root interactions in intercrops,ensified cropping systems using chemical and mechanical inputs also show that facilitative interactions definitely can be of significance. It is concluded that a better understanding of the mechanisms behind facilitative interactions may allow us to benefit more from these phenomena in agriculture a

,Root-to-shoot signalling: Assessing the roles of ‘up’ in the up and down world of long-distance sigsome systems has lead to the conclusions that other novel signals can be important. The efficacy of a given signal molecule can depend on the shoot water and nutrient status, as demonstrated by variation in stomatal responses to abscisic acid. If such variation is widespread in crop species, this ma
