Plants interact with a large number of microorganisms that greatly influence their growth and
health. Among the beneficial microorganisms, rhizosphere bacteria known as Plant Growth …

Sigma (σ) factors are key regulatory proteins that control the transcription initiation in
prokaryotes. In response to environmental or developmental cues, σ factors initiate the …

The genome of Azospirillum brasilense encodes five RpoH sigma factors: two OxyR
transcription regulators and three catalases. The aim of this study was to understand the role …

Carotenoids constitute an important component of the defense system against
photooxidative stress in bacteria. In Azospirillum brasilense Sp7, a nonphotosynthetic …

Azospirillum brasilense Az19 is a plant-beneficial bacterium capable of protecting plants
from the negative effects of drought. The objective of this study was to determine and …

Azospirillum brasilense Sp7 produces PHB, which is covered by granule-associated
proteins (GAPs). Phasins are the main GAPs. Previous studies have shown phasins can …

Fasciclin domain proteins (FDP) are found in all domains of life, but their biological role and
regulation are not clearly understood. While studying the proteome of a mutant (Car1) of …

Proteus mirabilis isolates commonly have decreased susceptibility to imipenem. Previously,
we found P. mirabilis hfq mutant was more resistant to imipenem and an outer membrane …

Aims: Azospirillum brasilense harbors two redox-sensitive Zinc-binding anti-sigma (ZAS)
factors (ChrR1 and ChrR2), which negatively regulate the activity of their cognate extra …

Abstract Extra Cytoplasmic Function (ECF) σ factor/regulatory protein (anti-σ factor) pairs
govern environment mediated changes in gene expression in bacteria. The release of the …
