Polyamines are considered as plant growth regulating compounds; among them, cadaverine has been correlated with root growth promotion or osmotic stress mitigation in some plant species. The purpose of this study was to evaluate the capacity of bacterial Azospirillum brasilense Az39 strain to produce cadaverine in chemically defined medium and inoculated plants, and to correlate this capacity wi...

Low concentrations of auxin (e.g. 10(-10)m) do not promote the growth of intact seedling roots of maize (Zea mays L. Bear Hybrid WF 9 x 38). Higher concentrations are inhibitory. When the roots are pretreated with the ethylene biosynthesis inhibitors, cobalt and aminoethoxyvinylglycine, auxin (10(-10) to 10(-8)m) strongly promotes their growth. The promotion of growth by auxin in pretreated roo...

Bacillus sp. strain RZ2MS9 is a multitrait soybean and maize growth-promoting bacterium isolated in Brazil from guarana's rhizosphere. Here, we present the draft genome sequence of RZ2MS9 and its genes involved in many features related to plant growth promotion.

Bacillus pumilus strain WP8 is an efficient plant growth-promoting rhizobacterium. Here, we present the complete genome of WP8 and its genes involved in plant growth promotion and biocontrol.

We extracted volatile organic compounds (VOCs) emitted by a plant growth-promoting fungus (PGPF) Phoma sp. GS8-3 by gas chromatography and identified them by mass spectrometry. All of the identified compounds belonged to C4-C8 hydrocarbons. Volatiles varied in number and quantity by the culture period of the fungus (in days). 2-Methyl-propanol and 3-methyl-butanol formed the main components of ...
