Insight into the Taxonomic and Functional Diversity of Bacterial Communities Inhabiting Blueberries in Portugal
Microorganisms. 2022 Nov 4;10(11):2193. doi: 10.3390/microorganisms10112193.
ABSTRACT
Vaccinium myrtillus is a dwarf shrub of the Ericaceae family with a Palearctic distribution, associated with temperate and cold humid climates. It is widespread on the European continent; on the Iberian Peninsula it is located on Atlantic climate mountains and glacial relicts. In Portugal, we find scattered and interesting populations; however, the majority of them are threatened by climate change and wildfires. Given that, the objective of this study is to determine the rhizospheric and root bacterial communities of this plant in the southernmost regions, and, consequently, its potential range and ability to be used as a biofertilizer. In this work, metabarcoding of 16S rRNA gene showed that the endophytic bacterial diversity is dependent on the plant and selected by it according to the observed alpha and beta diversity. Moreover, a culturomic approach allowed 142 different strains to be isolated, some of them being putative new species. Additionally, some strains belonging to the genera Bacillus, Paenibacillus, Pseudomonas, Paraburkholderia, and Caballeronia showed significant potential to be applied as multifunctional biofertilizers since they present good plant growth-promoting (PGP) mechanisms, high colonization capacities, and an increase in vegetative parameters in blueberry and tomato plants.
