Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance
plant growth by a wide variety of mechanisms like phosphate solubilization, siderophore …

The rhizosphere encompasses the millimeters of soil surrounding a plant root where
complex biological and ecological processes occur. This review describes recent advances …

Bacteria communicate with one another using chemical signal molecules. As in higher
organisms, the information supplied by these molecules is critical for synchronizing the …

▪ Abstract Prokaryotic biofilms that predominate in a diverse range of ecosystems are often
composed of highly structured multispecies communities. Within these communities …

Excessive and indiscriminate use of antibiotics to treat bacterial infections has lead to the
emergence of multiple drug resistant strains. Most infectious diseases are caused by …

Background Biofilms are multicellular communities of microorganisms held together by a self-
produced extracellular matrix. The ability of microbes to form biofilm is a universal …

Quorum sensing (QS) refers to the capacity of bacteria to monitor their population density
and regulate gene expression accordingly: the QS-regulated processes deal with …

It has become increasingly and widely recognised that bacteria do not exist as solitary cells,
but are colonial organisms that exploit elaborate systems of intercellular communication to …

▪ Abstract Quorum sensing is an example of community behavior prevalent among diverse
bacterial species. The term “quorum sensing” describes the ability of a microorganism to …

Efflux pumps are widely implicated in antibiotic resistance because they can extrude the
majority of clinically relevant antibiotics from within cells to the extracellular environment …
