dc.description.abstract | Seed microbiota is becoming an emergent area of research. Host plant microbial
diversity is increasingly well described, yet relatively little is known about the stressors
driving plant endomicrobiota at the metaorganism level. The present work examines the
role of horizontal and vertical transmission of bacterial microbiota in response to abiotic
stress generated by arsenic. Horizontal transmission is achieved by bioaugmentation
with the endophyte Rhodococcus rhodochrous, while vertical transmission comes via
maternal inheritance from seeds. To achieve this goal, all experiments were conducted
with two Jasione species. J. montana is tolerant to arsenic (As), whereas J. sessiliflora,
being phylogenetically close to J. montana, was not previously described as As tolerant.
The Jasione core bacterial endophytes are composed of genera Pseudomonas,
Ralstonia, Undibacterium, Cutibacterium, and Kocuria and family Comamanadaceae
across different environmental conditions. All these operational taxonomic units (OTUs)
coexisted from seeds to the development of the seedling, independently of As stress,
or bioaugmentation treatment and Jasione species. R. rhodochrous colonized efficiently
both species, driving the endomicrobiota structure of Jasione with a stronger effect than
As stress. Despite the fact that most of the OTUs identified inside Jasione seeds and
seedlings belonged to rare microbiota, they represent a large bacterial reservoir offering
important physiological and ecological traits to the host. Jasione traits co-regulated
with R. rhodochrous, and the associated microbiota improved the host response to
As stress. NGS-Illumina tools provided further knowledge about the ecological and
functional roles of plant endophytes. | es |
