Salinity stress is one of the major abiotic stresses limiting crop production in arid and semi-
arid regions. Interest is increasing in the application of PGPRs (plant growth promoting …

Numerous studies have reported the stimulation of plant growth following inoculation with an
IAA-producing PGPB. However, the specific mode of IAA production by the PGPB is rarely …

As one of the major non–biological stresses, soil salinity negatively affects agricultural
productivity, microbial communities, and agricultural economics in impacted areas and is a …

Background Soil salinity and drought are an enormous worldwide problem for agriculture,
horticulture and silviculture. The initial responses of plants to drought and salinity are similar; …

Abstract Indole-3-acetic acid (IAA) is an important phytohormone with the capacity to control
plant development in both beneficial and deleterious ways. The ability to synthesize IAA is …

Although plant roots encounter a plethora of microorganisms in the surrounding soil, at the
rhizosphere, plants exert selective forces on their bacterial colonizers. Unlike immune …

Bacterial root endophytes reside in a vast number of plant species as part of their root
microbiome, with some being shown to positively influence plant growth. Endophyte …

Microbial synthesis of the phytohormone auxin has been known for a long time. This
property is best documented for bacteria that interact with plants because bacterial auxin …

Diverse bacterial species possess the ability to produce the auxin phytohormone indole-3-
acetic acid (IAA). Different biosynthesis pathways have been identified and redundancy for …

The plant signaling molecule auxin is present in multiple kingdoms of life. Since its
discovery, a century of research has been focused on its action as a phytohormone. In land …
