Complete genome sequence analysis of plant growth-promoting bacterium, Isoptericola sp. AK164 isolated from the rhizosphere of Avicennia marina growing at the Red Sea coast. ACT flea iflavirus

The coastal areas of the Red Sea are one of the unique extreme environments with high biodiversity revealing large microbial communities with a high abundance of Actinobacteria in the mangrove forests of Avicennia marina.Those Actinobacteria are Gram-positive bacteria which show a remarkable range of morphologies, including unicellular cocci or rods and differentiated branched multicellular bacteria.They usually grow in numerous habitats, especially extreme environments, such as salt marshes, hot springs, alkaline saline soils, deep-sea sediments, and the microbiome of a higher eukaryote. The ability of the Actinobacteria to adapt to those extreme environments is correlated to their production of bioactive natural products and secondary metabolites with diverse functions, including the cycling of complex carbon substrates in benthic ocean habitats.On the other hand, Actinobacteria are important plant symbionts that play a crucial role in enhancing plant growth as plant growth promotion bacteria (PGPB) and protection against pathogens. The genus Isoptericola is found to be involved in phosphate uptake and the degradation of cellulose, hemicellulose, and chitin. Noteworthy, it has been revealed that ACC deaminase-producing strains of Isoptericola stimulated the growth of the host plant and influenced flavonoid accumulation, which is known for prominent roles in stress alleviation. There is a need to study this phylum of bacteria as bioactive compound producers along with the metabolism and genetic structure governing this ecological context. Here, we report the genome sequence analysis of Isoptericola sp. AK164, plant growth promoting rhizosphere bacterium isolated from the rhizosphere of Avicennia marina growing at the Red Sea shore in Thuwal, Saudi Arabia, highlighting their plant growth properties and potential biotechnological application. Genome sequencing and analysis, of rhizosphere bacteria e.g. AK164 for their potential plant growth promoting activities under different growth conditions will speed up the applications of biostimulants in smart agriculture system as an eco-friendly solution to mitigate the negative impact of climate change.
