The Role of Soil Microorganisms in Plant Mineral Nutrition—Current Knowledge and Future Directions

Frontiers in Plant Science, Journal Year: 2017, Volume and Issue: 8

Published: Sept. 19, 2017

In their natural environment plants are part of a rich ecosystem including numerous and diverse microorganisms in the soil. It has been long recognized that some these microbes, such as mycorrhizal fungi or nitrogen fixing symbiotic bacteria, play important roles plant performance by improving mineral nutrition. However, full range microbes associated with potential to replace synthetic agricultural inputs only recently started be uncovered. last few years great progress made knowledge on composition rhizospheric microbiomes dynamics. There is clear evidence shape microbiome structures, most probably root exudates, also bacteria have developed various adaptations thrive niche. The mechanisms interactions processes driving alterations however largely unknown. this review we focus interaction enhancing nutrition, summarizing current several research fields can converge improve our understanding molecular underpinning phenomenon.

Plant health: feedback effect of root exudates-rhizobiome interactions

Applied Microbiology and Biotechnology, Journal Year: 2018, Volume and Issue: 103(3), P. 1155 - 1166

Published: Dec. 20, 2018

The well-being of the microbial community that densely populates rhizosphere is aided by a plant's root exudates. Maintaining health key factor in its continued existence. As minute as rhizospheric microbes are, their importance plant growth cannot be overemphasized. They depend on plants for nutrients and other necessary requirements. relationship between rhizosphere-microbiome (rhizobiome) hosts can beneficial, non-effectual, or pathogenic depending involved. This relationship, to large extent, determines fate host survival. Modern molecular techniques have been used unravel rhizobiome species' composition, but interplay exudates factors maintenance healthy not yet thoroughly investigated. Many functional proteins are activated upon contact with external factors. These may elicit promoting suppressing responses from plants. To optimize productivity plants, diversity modulatory need clearly understood improved health.

Evolutionary conservation of a core root microbiome across plant phyla along a tropical soil chronosequence

Nature Communications, Journal Year: 2017, Volume and Issue: 8(1)

Published: Aug. 2, 2017

Culture-independent molecular surveys of plant root microbiomes indicate that soil type generally has a stronger influence on microbial communities than host phylogeny. However, these studies have mostly focussed model plants and crops. Here, we examine the multiple phyla including lycopods, ferns, gymnosperms, angiosperms across chronosequence using 16S rRNA gene amplicon profiling. We confirm is primary determinant root-associated bacterial community composition, but also observe significant correlation with A total 47 genera are associated roots relative to bulk communities, well-recognized plant-associated such as Bradyrhizobium, Rhizobium, Burkholderia, major uncharacterized lineages WPS-2, Ellin329, FW68. suggest taxa collectively constitute an evolutionarily conserved core microbiome at this site.

Metabolic regulation of the maize rhizobiome by benzoxazinoids

The ISME Journal, Journal Year: 2019, Volume and Issue: 13(7), P. 1647 - 1658

Published: Feb. 22, 2019

Abstract The rhizobiome is an important regulator of plant growth and health. Plants shape their communities through production release primary secondary root metabolites. Benzoxazinoids (BXs) are common tryptophan-derived metabolites in grasses that regulate belowground aboveground biotic interactions. In addition to biocidal activity, BXs can plant–biotic interactions as semiochemicals or within-plant defence signals. However, the full extent mechanisms by which root-associated microbiome has remained largely unexplored. Here, we have taken a global approach examine regulatory activity on maize metabolome associated bacterial fungal communities. Using untargeted mass spectrometry analysis combination with prokaryotic amplicon sequencing, compared impacts three genetic mutations different steps BX pathway. We show metabolism concurrently influence type-dependent manner. Correlation between BX-controlled taxa suggested dominant role for BX-dependent metabolites, particularly flavonoids, constraining range soil microbial taxa, while stimulating methylophilic bacteria. Our study supports multilateral model control root–microbe via function metabolism.
