“…The extremophiles associated with plants are classified as bacteria, archaea, and eukaryotes, and further into different groups, e.g., Bacteroidetes , Ascomycota , Basidiomycota , Euryarchaeota , Firmicutes , Actinobacteria , Crenarchaeota , and Proteobacteria . As the beneficial associate, the plant-associated extremophiles display multiple ecological and plant growth promotion (PGP) attributes, positively impacting their plant counterparts [ 11 , 12 , 13 ]. The plant-associated rhizospheric microbes are present in the root zone and key examples include Paenibacillus , Burkholderia , Azospirillum , Bacillus , Methylobacterium , and Pseudomonas , etc.…”
