英文摘要 | The Queretaro semi-desert in central Mexico is the most southern extension of the Chihuahua desert. This semi-arid zone shelters a vast cactus diversity with many endemic species. Currently, two cacti species from this semi-desert namely,Echinocactus platyacanthusandNeobuxbaumia polylophaare under a threat to their survival. So far, there are no reports on the bacterial communities associated with these plants. In this study, we assessed the structure and diversity of the rhizospheric bacterial communities associated withEchinocactus platyacanthusandNeobuxbaumia polylophagrowing in wild and cultivated conditions. Samples ofE. platyacanthuswere also approached with culture-based methods in search of isolates with plant growth promoting abilities. Metagenomic DNA was extracted from rhizospheric samples and used for Illumina sequencing of the 16S rRNA gene. alpha-diversity and amplicon sequence variant (ASV) richness were higher in both groups ofE. platyacanthussamples. All samples accounted for 14 phyla, and the major 6 were common to all treatments. The dominant phyla in all four sample groups wereActinobacteriaandProteobacteria. Analysis at family and genus levels showed association patterns with the cultivated samples from both species grouping together, while the wild samples of each cactus species were grouping apart. High abundance values of Rubrobacteraceae (15.9-18.4%) were a characteristic feature of wildE. platyacanthussamples. In total, 2,227 ASVs were scored in all 12 rhizospheric samples whereE. platyacanthussamples showed higher richness with 1,536 ASVs. Regarding the growing conditions, both groups of cultivated samples were also richer accounting for 743 and 615 ASVs forE. platyacanthusandN. polylopha, respectively. The isolates fromE. platyacanthusrhizosphere were mainly assigned toBacilliandGammaproteobacteria. In total 35 strains were assayed for PGPR traits (IAA and siderophore production, phosphate solubilization, and fungal growth inhibition). Strains obtained from plants growing in the wild displayed better PGPR characteristics, stressing that naturally occurring wild plants are a source of bacteria with diverse metabolic activities, which can be very important players in the adaptation of cacti to their natural environments. |
