Summary The plant endosphere is colonized by complex microbial communities and microorganisms, which colonize the interior at least part of their lifetime are termed endophytes. Their functions range from mutualism to pathogenicity. All organs tissues generally bacterial endophytes diversity composition depend on plant, organ its physiological conditions, growth stage as well environment. Plant‐associated in particular endophytes, have lately received high attention, because increasing awareness importance host‐associated microbiota for functioning performance host. Some endophyte known mostly lab assays, genome prediction few metagenome analyses; however, we limited understanding planta activities, particularly considering micro‐environments dynamics conditions. In our review, present recent findings environments, conditions colonization. Furthermore, discuss functions, interaction between plants methodological limitations research. We also provide an outlook needs future research improve role colonizing traits ecosystem functioning.

Experimental evidence of microbial inheritance in plants and transmission routes from seed to phyllosphere and root

Environmental Microbiology, Journal Year: 2021, Volume and Issue: 23(4), P. 2199 - 2214

Published: Jan. 15, 2021

While the environment is considered primary origin of plant microbiome, potential role seeds as a source transmitting microorganisms has not received much attention. Here we tested hypothesis that microbiome partially inherited through vertical transmission. An experimental culturing device was constructed to grow oak seedlings in microbe-free while keeping belowground and aboveground tissues separated. The microbial communities associated with acorn's embryo pericarp developing seeding's phyllosphere root systems were analysed using amplicon sequencing fungal ITS bacterial 16S rDNA. Results showed seed diverse non-randomly distributed within an acorn. composition strongly resembled found embryo, whereas roots each had less distinct community. Our findings demonstrate high level diversity spatial partitioning community both seedling, indicating inheritance, niche differentiation divergent transmission routes for establishment communities.

Microbiome Modulation—Toward a Better Understanding of Plant Microbiome Response to Microbial Inoculants

Frontiers in Microbiology, Journal Year: 2021, Volume and Issue: 12

Published: April 8, 2021

Plant-associated microorganisms are involved in important functions related to growth, performance and health of their hosts. Understanding modes action is for the design promising microbial inoculants sustainable agriculture. able interact with hosts often exert specific toward potential pathogens; underlying vitro interactions well studied. In contrast, situ effects inoculants, especially impact on plant indigenous microbiome was mostly neglected so far. Recently, research has revolutionized our understanding plants as coevolved holobionts but also microbiome-inoculant interactions. Here we disentangle point out following types modulations: (i) transient shifts, (ii) stabilization or increase diversity, (iii) evenness, (iv) restoration a dysbiosis/compensation reduction pathogen-induced shift, (v) targeted shifts beneficial members microbiota, (vi) suppression pathogens. Therefore, suggest modulations novel efficient mode that can be mediated via plant.

From seed to seed: the role of microbial inheritance in the assembly of the plant microbiome

Trends in Microbiology, Journal Year: 2022, Volume and Issue: 31(4), P. 346 - 355

Published: Dec. 5, 2022

Despite evidence that the microbiome extends host genetic and phenotypic traits, information on how is transmitted maintained across generations remains fragmented. For seed-bearing plants, seeds harbor a distinct play unique role by linking one generation to next. Studies microbial inheritance, process we suggest including both vertical transmission subsequent migration of seed microorganisms new plant, thus become essential for our understanding evolutionary potential host–microbiome coevolution. We propose dividing inheritance into three stages: (i) plant seed, (ii) dormancy, (iii) seedling. discuss factors affecting assembly during stages, highlight future research directions, emphasize implications fundamental science society.

Seed-associated bacteria represent an important reservoir of microorganisms passed onto progeny plants and have been postulated to be for early plant development vigor. According a few reports, some bacterial taxa seem transferred from seed seed-associated may derive insect visits during flowering; however, the origin endophytes is poorly understood. To better understand origin, ecology, functional role endophytes, we planted Setaria viridis seeds over several generations in sterile growth substrate. Seed microbiota each generation were analyzed by next sequencing 16S rRNA genes characterized regarding their germination growth. Growing (or highly depleted) substrate resulted microbiota, which largely less diverse had altered community composition, particularly at later generations, indicating that soil microbiota. Some inherited seeds; different subsets seeds/seed batches across generations. This suggests other factors than host control establishment most only few, e.g., obligate might consistently inherited. Furthermore, observed drastic decline vigor affected. Overall, our results demonstrated supply external sources such as soil/rhizosphere environment build-up healthy microbiome warranting plants.
