Plant Selenium Hyperaccumulation Affects Rhizosphere: Enhanced Species Richness and Altered Species Composition

Popis výsledku v původním jazyce

Relatively little is known about the microbiomes of plants with extreme properties, including plants that hyperaccumulate toxic elements such as selenium (Se). Selenium hyperaccumulators may contain up to 1.5% of their dry weight in Se, which can cause toxicity to herbivores and pathogens as well as neighboring plants. To investigate whether plant Se affects rhizomicrobial diversity and composition, we used a combination of culture-based and culture-independent approaches. Using 16S rRNA Illumina sequencing, we show that the rhizobiomes of Se hyperaccumulators are significantly different from non-accumulators from the same naturally seleniferous site, with a higher occurrence of Pedobacter and Deviosa surrounding hyperaccumulators. In addition, we found that hyperaccumulators harbor a higher species richness when compared to non-accumulators on the same seleniferous site. Thus, hyperaccumulation does not appear to negatively affect rhizobiome diversity, and may select for certain bacterial taxa in the rhizobiome. The bacterial isolates, independent from site or host plant species were in general extremely resistant to toxic concentrations of Se (up to 200 mM selenate or selenite) and could reduce selenite to elemental Se. Thus, Se resistance in microbial symbionts may be widespread and not under selection by Se hyperaccumulators.
