Many plants have developed adaptations to environmental extremes such as drought and high salinity. Plant resilience can enhance the vast community of associated microorganisms, collectively known as the plant microbiome. Among these beneficial bacteria, members of the Pseudomonas genus are known for their plant-growth-promoting properties.

Two strains of the Pseudomonas species, known as E102 and E141, have been the subject of a study to examine how these bacteria interact with plants to promote growth under stress by a team of researchers led by KAUST’s Ramona Marasco, Ikram Blilou and Daniele Daffonchio. The effects of these strains, which were isolated from date palm roots, have been shown to promote drought tolerance and resistance to salinity in date palms and other plants.
