The objective of the study was to determine the most suitable cyst forming media in liquid conditions. Encystation in Azospirillum brasilense Cd was observed by using routine laboratory staining and microscopy. Best encystment occurred in liquid or semisolid media containing fructose (8 mM) and KNO3(0.5 mM). The encysted forms consisted of a central body filled with poly-β -hydroxybutyric acid ...

Transcription of the Azospirillum brasilense ipdC gene, encoding an indole-3-pyruvate decarboxylase involved in the biosynthesis of indole-3-acetic acid (IAA), is induced by IAA as determined by ipdC-gusA expression studies and Northern analysis. Besides IAA, exogenously added synthetic auxins such as 1-naphthaleneacetic acid, 2,4-dichlorophenoxypropionic acid, and p-chlorophenoxyacetic acid we...

; Azospirillum spp. are endophytic bacteria with beneficial effects on cereals — effects partially attributed to gibberellin production by the microorganisms. Azospirillum lipoferum and Azospirillum brasilense inoculated to rice dy mutant reversed dwarfism in seedlings incubated with [17,17-H2]GA20 with formation of [17,17H2]GA1, showing the in vivo capacity to perform the 3 -hydroxylation. Whe...

Coffee production has decreased due to environmental and management factors. The current plantations are old unproductive, also the rust problem, caused by fungus Hemileia vastatrix Berk & Br. Furthermore, shade in systems with consequent increase soil erosion, addition agrochemicals. Currently, planting of new varieties resistance is increasing. it been shown that various biofertilized perenni...
