“…In addition to AM fungi, it harbours many different organisms and is highly influenced by plant root exudates (Badri et al 2009;Bais et al 2006;Barea et al 2005). Recently, a role for SLs in another important beneficial plant-microorganism association in the rhizosphere -nodulation -was described (Fig.…”

Background Plants are exposed to ever changing and often unfavourable environmental conditions, which cause both abiotic and biotic stresses. They have evolved sophisticated mechanisms to flexibly adapt themselves to these stress conditions. To achieve such adaptation, they need to control and coordinate physiological, developmental and defence responses. These responses are regulated through a complex network of interconnected signalling pathways, in which plant hormones play a key role. Strigolactones (SLs) are multifunctional molecules recently classified as a new class of phytohormones, playing a key role as modulators of the coordinated plant development in response to nutrient deficient conditions, especially phosphorus shortage. Belowground, besides regulating root architecture, they also act as molecular cues that help plants to communicate with their environment. Scope This review discusses current knowledge on the different roles of SLs below-ground, paying special attention to their involvement in phosphorus uptake by the plant by regulating root architecture and the establishment of mutualistic symbiosis with arbuscular mycorrhizal fungi. Their involvement in plant responses to other abiotic stresses such as drought and salinity, as well as in other plant-(micro)organisms interactions such as nodulation and root parasitic plants are also highlighted. Finally, the agronomical implications of SLs below-ground and their potential use in sustainable agriculture are addressed. Conclusions Experimental evidence illustrates the biological and ecological importance of SLs in the rhizosphere. Their multifunctional nature opens up a wide range of possibilities for potential applications in agriculture. However, a more in-depth understanding on the SL functioning/signalling mechanisms is required to allow us to exploit their full potential.

“…isolated from soil suggests that capacity to solubilize P is associated with phylogenetic lineage and that it may be feasible therefore to select specific microorganisms or communities for enhanced capacity to mobilize P (Browne et al, 2009). Microbial activity and community composition in the rhizosphere is driven not only by availability of C, but also by interaction with various plant-and microbially derived signal molecules (Bais et al, 2006;Badri et al, 2009). These secondary metabolites include flavonoids, phytoalexins, and other antimicrobial compounds, various phytostimulants (e.g.…”

“…The plants form root microbiota by adjusting the root secretion in the form of carbon-rich exudates and it influence of microbial diversity, density and activity (Dennis et al, 2010). There has been considerable progress in understanding the signaling pathways and molecules emitted by plants in rhizosphere zone which involved in the recruitment of certain groups of microbes A number of experimental data show specificity of the interaction between plant species and associated rhizobacterial communities (Badri et al, 2009;Sugiyama et al, 2013). In this respect, the specificity of rhizosphere at the patho-system with broomrapes is much more complicated.…”
