Impact of pollution on microbiological dynamics in the pistil stigmas of Orobanche lutea flowers (Orobanchaceae).

ABSTRACT: Our understanding of the basic relationships of microbiota associated with flowers is still quite limited, especially regarding parasitic plant species. The transient nature of flower parts such as pistil stigmas provides a unique opportunity for temporal investigations. This is the first report of the analysis of bacterial and fungal communities associated with the pistil stigmas of the lucerne parasite, Orobanche lutea. We compared the microorganism communities at different developmental stages and assessed the impact of pollution at the sampling sites. We also examined the plant growth properties (PGP) of bacteria in a culture-dependent analysis. The predominant colonizers of the pistil stigmas were Proteobacteria (99.25%), with Enterobacteriaceae (49.88%) and Pseudomonadaceae (48.28%)
