PLoS Biology, Journal Year: 2016, Volume and Issue: 14(1), P. e1002352 - e1002352

Plant-associated microorganisms have been shown to critically affect host physiology and performance, suggesting that evolution ecology of plants animals can only be understood in a holobiont (host its associated organisms) context. Host-associated microbial community structures are affected by abiotic factors, increased attention is given the role microbiome interactions such as pathogen inhibition. However, little known about how these factors act on community, especially what microbe–microbe interaction dynamics play. We begun address this knowledge gap for phyllosphere microbiomes simultaneously studying three major groups Arabidopsis thaliana symbionts (bacteria, fungi oomycetes) using systems biology approach. evaluated multiple potential control: we sampled various wild A. populations at different times, performed field plantings with genotypes, implemented successive colonization experiments under lab conditions where genotype, was manipulated.

A review on the plant microbiome: Ecology, functions, and emerging trends in microbial application

Journal of Advanced Research, Journal Year: 2019, Volume and Issue: 19, P. 29 - 37

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. This paper reviews importance functionalities bacterial discusses concepts regard plant-associated bacteria.

Microbial interactions within the plant holobiont

Microbiome, Journal Year: 2018, Volume and Issue: 6(1)

Published: March 27, 2018

Since the colonization of land by ancestral plant lineages 450 million years ago, plants and their associated microbes have been interacting with each other, forming an assemblage species that is often referred to as a "holobiont." Selective pressure acting on holobiont components has likely shaped plant-associated microbial communities selected for host-adapted microorganisms impact fitness. However, high densities detected tissues, together fast generation time more ancient origin compared host, suggest microbe-microbe interactions are also important selective forces sculpting complex assemblages in phyllosphere, rhizosphere, endosphere compartments. Reductionist approaches conducted under laboratory conditions critical decipher strategies used specific cooperate compete within or outside tissues. Nonetheless, our understanding these shaping communities, along relevance host health natural context, remains sparse. Using examples obtained from reductionist community-level approaches, we discuss fundamental role (prokaryotes micro-eukaryotes) community structure health. We provide conceptual framework illustrating among microbiota members establishment maintenance host-microbial homeostasis.

Host genotype and age shape the leaf and root microbiomes of a wild perennial plant

Nature Communications, Journal Year: 2016, Volume and Issue: 7(1)

Published: July 12, 2016

Bacteria living on and in leaves roots influence many aspects of plant health, so the extent a plant's genetic control over its microbiota is great interest to crop breeders evolutionary biologists. Laboratory-based studies, because they poorly simulate true environmental heterogeneity, may misestimate or totally miss certain host genes microbiome. Here we report large-scale field experiment disentangle effects genotype, environment, age year harvest bacterial communities associated with Boechera stricta (Brassicaceae), perennial wild mustard. Host microbiome evident but not roots, varies substantially among sites. Microbiome composition also shifts as plants age. Furthermore, large proportion leaf groups are shared suggesting inoculation from soil. Our results demonstrate how genotype-by-environment interactions contribute complexity assembly natural environments.

Plants do not grow as axenic organisms in nature, but host a diverse community of microorganisms, termed the plant microbiota. There is an increasing awareness that microbiota plays role growth and can provide protection from invading pathogens. Apart intense research on crop plants, Arabidopsis emerging valuable model system to investigate drivers shaping stable bacterial communities leaves roots tool decipher intricate relationship among its colonizing microorganisms.

Plant compartment and biogeography affect microbiome composition in cultivated and native Agave species

New Phytologist, Journal Year: 2015, Volume and Issue: 209(2), P. 798 - 811

Published: Oct. 15, 2015

Desert plants are hypothesized to survive the environmental stress inherent these regions in part thanks symbioses with microorganisms, and yet microbial species, communities they form, forces that influence them poorly understood. Here we report first comprehensive investigation of associated species Agave, which native semiarid arid Central North America emerging as biofuel feedstocks. We examined prokaryotic fungal rhizosphere, phyllosphere, leaf root endosphere, well proximal distal soil samples from cultivated agaves, through Illumina amplicon sequencing. Phylogenetic profiling revealed composition was primarily determined by plant compartment, whereas mainly influenced biogeography host species. Cultivated A. tequilana exhibited lower levels diversity compared although no differences were found endosphere. Agaves shared core taxa known promote growth confer tolerance abiotic stress, suggests common principles underpinning Agave-microbe interactions.
