Biological nitrogen fixation in rhizobia occurs primarily in root or stem nodules and is
induced by the bacteria present in legume plants. This symbiotic process has fascinated …

The symbiosis between legumes and nitrogen fixing bacteria called rhizobia leads to the
formation of root nodules. Nodules are highly organized root organs that form in response to …

Highlights•Nitric oxide and reactive oxygen species are major players of biotic interactions in
plants.•Nitric oxide and reactive oxygen species signaling pathways are …

Nitric oxide (NO) is a signaling and defense molecule of major importance in living
organisms. In the model legume Medicago truncatula, NO production has been detected in …

Abstract Significance: During the Legume–Rhizobium symbiosis, hydrogen peroxide (H2O2)
and nitric oxide (NO) appear to play an important signaling role in the establishment and the …

Legume root nodules are sites of intense biochemical activity and consequently are at high
risk of damage as a result of the generation of reactive oxygen species (ROS) and reactive …

over 30 years, during which time a considerable portfolio of knowledge has accumulated …

Anthropogenic activities, such as industrial processes, mining, and agriculture, lead to an
increase in heavy metal concentrations in soil, water, and air. Given their stability in the …

Micro-RNAs (miRNAs) play a pivotal role in the control of gene expression and regulate
plant developmental processes. miRNA 172 (miR172) is a conserved miRNA in plants …

Nitric oxide (NO) is emerging as an important regulatory player in the Rhizobium-legume
symbiosis, but its biological role in nodule functioning is still far from being understood. To …
