In addition to its role in water and nutrient uptake, the root system is fundamentally important
because it anchors a plant to its substrate. Although a wide variety of root systems exist …

During the last 35 years of studies of Azospirillum–plant interaction, over 20 proposals were
suggested for the mechanism of action by which Azospirillum spp., the most intensively …

Polyamines (PAs) are ubiquitous biogenic amines that have been implicated in diverse
cellular functions in widely distributed organisms. In plants, mutant and transgenic plants …

The functional analysis of phytohormone production, interaction, and regulation in higher
plants has re-emerged in the past 10 years due to spectacular advances in integrative study …

Arbuscular mycorrhizas enhance the drought tolerance of host plants through several
underlying mechanisms. Polyamines (PAs) are known to protect plant cells from the …

We evaluated phytohormone and polyamine biosynthesis, siderophore production, and
phosphate solubilization in two strains (Cd and Az39) of Azospirillum brasilense used for …

Plant-associated Stenotrophomonas isolates have great potential for plant growth
promotion, especially under stress conditions, due to their ability to promote tolerance to …

Polyamines are considered as plant growth regulating compounds; among them,
cadaverine has been correlated with root growth promotion or osmotic stress mitigation in …

During ontogeny, plants interact with a wide variety of microorganisms. The association with
mutualistic microbes results in benefits for the plant. By contrast, pathogens may cause a …

The root system of a plant consists of the primary, lateral and adventitious roots. Lateral roots
always develop from roots whereas adventitious roots form from stem or leaf-derived cells …
