Buffet hypothesis for microbial nutrition at the rhizosphere

Buffet hypothesis for microbial nutrition at the rhizosphere

An emphasis is made on the diversity of nutrients that rhizosphere bacteria may encounter derived from roots, soil, decaying organic matter, seeds, or the microbial community. This nutrient diversity may be considered analogous to a buffet and is contrasting to the hypothesis of oligotrophy at the rhizosphere. Different rhizosphere bacteria may have preferences for some substrates and this woul...

Microbial Interactions in the Rhizosphere

The diverse genetic and functional groups of the extensive soil microbial populations are known to carry out activities exerting a critical impact on soil functions (Barea et al., 2005b; Avis et al., 2008). Among other activities, soil rnicroorganisms propel the biogeochemical cycling of nutrients and organic matter and improve plant performance and soil quality, key issues for agroecosystem se...

Role of the rhizosphere in iron nutrition of plants

Microbial co-operation in the rhizosphere.

Soil microbial populations are immersed in a framework of interactions known to affect plant fitness and soil quality. They are involved in fundamental activities that ensure the stability and productivity of both agricultural systems and natural ecosystems. Strategic and applied research has demonstrated that certain co-operative microbial activities can be exploited, as a low-input biotechnol...

Rhizosphere Microbial Communication in Soil Nutrient Acquisition

Most of the upper layer of the earth’s terrestrial crust is or has been influenced by plant roots, so most soil is actually rhizosphere soil at one time or another. Through their physical, chemical, and biological interactions with the soil, roots play a major role in soil formation (Jenny, 1941) and soil function (Wardle et al., 2004). Microbes factor prominently in global nutrient and energy ...
