Published: March 20, 2019

Plants have evolved with a plethora of microorganisms having important roles for plant growth and health. A considerable amount information is now available on the structure dynamics microbiota as well functional capacities isolated community members. Due to interesting potential due current challenges in crop production there an urgent need bring microbial innovations into practice. Different approaches microbiome improvement exist. On one hand strains or strain combinations can be applied, however, field success often variable urgently required. Smart, knowledge-driven selection needed use suitable delivery formulations. other hand, farming practices genotype influence thus functioning. Therefore, appropriate breeding leading improved plant-microbiome interactions are avenues increase benefit microbiota. In conclusion, different making new generation inoculants application microbiome-based agro-management lines could lead better microbiome.

The Plant Microbiome: From Ecology to Reductionism and Beyond

Annual Review of Microbiology, Journal Year: 2020, Volume and Issue: 74(1), P. 81 - 100

Published: June 12, 2020

Methodological advances over the past two decades have propelled plant microbiome research, allowing field to comprehensively test ideas proposed a century ago and generate many new hypotheses. Studying distribution of microbial taxa genes across habitats has revealed importance various ecological evolutionary forces shaping microbiota. In particular, selection imposed by strongly shapes diversity composition microbiota leads adaptation associated with navigating immune system utilizing plant-derived resources. Reductionist approaches demonstrated that interaction between immunity is, in fact, bidirectional plants, microbiota, environment shape complex chemical dialogue collectively orchestrates plantmicrobiome. The next stage research will require integration reductionist establish general understanding assembly function both natural managed environments.

The present scenario of agricultural sector is dependent hugely on the use chemical-based fertilizers and pesticides that impact nutritional quality, health status, productivity crops. Moreover, continuous release these chemical inputs causes toxic compounds such as metals to accumulate in soil move plants with prolonged exposure, which ultimately human health. Hence, it becomes necessary bring out alternatives pesticides/fertilizers for improvement outputs. rhizosphere plant an important niche abundant microorganisms residing it. They possess properties growth promotion, disease suppression, removal compounds, assimilating nutrients plants. Utilizing beneficial microbes crop presents efficient way modulate yield by maintaining healthy status quality through bioformulations.

Rhizosphere community selection reveals bacteria associated with reduced root disease

Microbiome, Journal Year: 2021, Volume and Issue: 9(1)

Published: April 9, 2021

Abstract Background Microbes benefit plants by increasing nutrient availability, producing plant growth hormones, and protecting against pathogens. However, it is largely unknown how change root microbial communities. Results In this study, we used a multi-cycle selection system infection the soilborne fungal pathogen Rhizoctonia solani AG8 (hereafter AG8) to examine impact rhizosphere bacterial community recruit beneficial microorganisms suppress pathogens promote growth. Successive plantings dramatically enhanced disease suppression on susceptible wheat cultivars in greenhouse. Accordingly, analysis of soil using deep sequencing 16S rRNA genes revealed distinct profiles assembled over successive plantings. Moreover, cluster communities formed from AG8-infected was those without infection. Interestingly, with lowest gradually separated worst planting cycles. monocultures application increased abundance some genera which have potential antagonistic activities, such as Chitinophaga , Pseudomonas Chryseobacterium Flavobacterium group growth-promoting (PGP) nitrogen-fixing microbes, including Pedobacter Variovorax Rhizobium . Furthermore, 47 bacteria isolates belong 35 species were isolated. Among them, eleven five exhibited activities oryzae vitro respectively. Notably, Janthinobacterium displayed broad antagonism Pythium ultimum AG8, R. suppressive activity soil. Conclusions Our results demonstrated that can shape specifically accumulate microbes. findings suggest may offer for addressing agronomic concerns associated diseases crop productivity.

Successive passaging of a plant-associated microbiome reveals robust habitat and host genotype-dependent selection

Proceedings of the National Academy of Sciences, Journal Year: 2019, Volume and Issue: 117(2), P. 1148 - 1159

There is increasing interest in the plant microbiome as it relates to both health and agricultural sustainability. One key unanswered question whether we can select for a that robust after colonization of target hosts. We used successive passaging experiment address this by selecting upon tomato phyllosphere microbiome. Beginning with diverse microbial community generated from field-grown plants, inoculated replicate plants across 5 genotypes 4 45-d passages, sequencing at each passage. observed consistent shifts bacterial (16S amplicon sequencing) fungal (internal transcribed spacer region communities lines over time, well general loss diversity course experiment, suggesting much naturally likely transient or poorly adapted within experimental setting. found host genotype environment shape composition, but relative importance declines through time. Furthermore, using coalescence end was invasion starting community. These results highlight stable particular indeed possible, emphasizing great potential approach agriculture beyond. In light response selection absence reciprocal evolution (coevolution) described here, future studies should how such adaptation influences health.
