The rhizobium–legume symbiosis is a major source of fixed nitrogen (ammonia) in the
biosphere. The potential for this process to increase agricultural yield while reducing the …

The mutualistic association between leguminous plants and endosymbiotic rhizobial
bacteria is a paradigmatic example of a symbiosis driven by metabolic exchanges. Here, we …

There is strong selection for the evolution of systems that protect bacterial populations from
viral attack. We report a single phage defense protein, Hna, that provides protection against …

Maintenance of cellular phosphate homeostasis is essential for cellular life. The PhoU
protein has emerged as a key regulator of this process in bacteria, and it is suggested to …

Symbiotic nitrogen fixation (SNF) is an energetically expensive process performed by
bacteria during endosymbiotic relationships with plants. The bacteria require the plant to …

Sinopodophyllum hexandrum, a perennial rhizomatous herb that produces the anti-cancer
metabolite podophyllotoxin (PPT), is distributed in the Himalayan region. While greater plant …

The bacterium Sinorhizobium meliloti Rm2011 forms N2-fixing root nodules on alfalfa and
other leguminous plants. The pSymB chromid contains a 110-kb region (the ETR region) …

Host/symbiont compatibility is a hallmark of the symbiotic nitrogen‐fixing interaction between
rhizobia and legumes, mediated in part by plant‐produced nodule‐specific cysteine‐rich …

Diseases caused by phytopathogenic bacteria are responsible for significant economic
losses, and these bacteria spread through diverse pathways including waterways and …

The order Rhizobiales contains numerous agriculturally, biotechnologically, and medically
important bacteria, including the rhizobia, and the genera Agrobacterium, Brucella, and …
