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 …

Our knowledge of the microbiology of the phyllosphere, or the aerial parts of plants, has
historically lagged behind our knowledge of the microbiology of the rhizosphere, or the …

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 …

Aerial plant surfaces represent the largest biological interface on Earth and provide
essential services as sites of carbon dioxide fixation, molecular oxygen release, and primary …

Background Pseudomonas fluorescens are common soil bacteria that can improve plant
health through nutrient cycling, pathogen antagonism and induction of plant defenses. The …

Bacterial pathogens regulate virulence factor gene expression coordinately in response to
environmental stimuli, including nutrient starvation. The phosphate (Pho) regulon plays a …

Ethanolamine is a compound that can be readily derived from cell membranes and that
some bacteria can use as a source of carbon and/or nitrogen. The complex biology and …

Diverse gram-negative bacteria deliver effector proteins into the cells of their eukaryotic
hosts using the type III secretion system. Collectively, these type III effector proteins function …

Soft-rot Enterobacteriaceae (SRE), which belong to the genera Pectobacterium and
Dickeya, consist mainly of broad host-range pathogens that cause wilt, rot, and blackleg …

Abstract Indole-3-acetic acid (IAA), a fundamental phytohormone categorized under auxins,
not only influences plant growth and development but also plays a critical role in plant …
