Bacteria have evolved many different signal transduction systems that sense signals and
generate a variety of responses. Generally, most abundant are transcriptional regulators …

The most common prokaryotic signal transduction mechanisms are the one-component
systems in which a single polypeptide contains both a sensory domain and a DNA-binding …

Key message Compatible interaction between rhizobial Nod factors and host receptors
enables initial recognition and signaling events during legume-rhizobia symbiosis. Abstract …

In the well‐known legume–rhizobia symbiosis, flavonoids released by legume roots induce
expression of the Nod factors and trigger early plant responses involved in root nodulation …

Nodulation competition is a key factor that limits symbiotic nitrogen fixation between rhizobia
and their host legumes. Soybean root exudates (SREs) are thought to act as signals that …

Hydroxytropolone (7-HT) is a symmetrical seven-membered heteroatomic ring with a
carboxyl group and two hydroxyl groups and was recently reported to be an iron scavenger …

As flavonoids have beneficial health effects on humans, they are gaining increasing interest
from pharmaceutical and health industries. However, current production methods, such as …

Bacillus subtilis collectively inhabits the rhizosphere, where it contributes to the promotion of
plant growth, although it does not have a direct symbiotic relationship to plants as observed …

Symbiotic nitrogen fixation (SNF) by rhizobia is not only the main natural bionitrogen-source
for organisms but also a green process leveraged to increase the fertility of soil for …

The divergently oriented Sinorhizobium meliloti emrAB (SMc03168 and SMc03167) and
emrR (SMc03169) genes are predicted to encode an efflux system of the major facilitator …
