Rhizobia - Wikipedia
网页Rhizobia are a "group of soil bacteria that infect the roots of legumes to form root nodules". [2] Rhizobia are found in the soil and, after infection, produce nodules in the legume where they fix nitrogen gas (N 2 ) from the atmosphere, turning it …
Rhizobia: from saprophytes to endosymbionts - Nature
网页2018年1月30日 · Rhizobia are some of the best-studied plant microbiota. These oligotrophic Alphaproteobacteria or Betaproteobacteria form symbioses with their legume hosts. Rhizobia must exist in soil and...
Rhizobium: nitrogen fixing bacteria – Inanimate Life - Geneseo
网页Rhizobia are one of several group of bacteria capable of ‘fixing’ nitrogen, i.e. converting dinitrogen gas into ammonia and then into organic molecules such as amino acids.
INTRODUCTION TO RHIZOBIA - University of Hawaiʻi
网页Rhizobia are special bacteria that can live in the soil or in nodules formed on the roots of legumes. In root nodules, they form a symbiotic association with the legume, obtaining nutrients from the plant and producing nitrogen in a process called biological nitrogen fixation, or BNF.
17.2C: Symbiotic Nitrogen Fixation - Biology LibreTexts
网页2022年5月14日 · Rhizobia. Rhizobia are Gram-negative bacilli that live freely in the soil (especially where legumes have been grown). However, they cannot fix atmospheric nitrogen until they have invaded the roots of the appropriate legume.
Rhizobia: A Promising Source of Plant Growth-Promoting …
网页2023年6月21日 · For over a century, the scientific community has had a comprehensive understanding of how rhizobia can promote the growth of legumes by forming nitrogen fixing nodules. Despite this knowledge, the interaction of rhizobia with non-legumes has remained largely ignored as a subject of study until more recent decades.
Symbiotic nitrogen fixation by rhizobia - ScienceDirect
网页2018年8月1日 · Rhizobia have solved the paradox between their strict aerobic status and the extreme sensitivity of nitrogenase to oxygen by inducing new organs, the nodules, which exhibit an extremely low free oxygen atmosphere and synthesize a form of plant hemoglobin — leghemoglobin — that facilitates O 2 diffusion to bacteroids.
Plant-Rhizobia Relationship | Crop Science US - Bayer
网页2024年2月21日 · Legume plants can form a symbiotic relationship with rhizobia, a type of soil bacteria, that can fix nitrogen (pull nitrogen out of the air and move it into the soil), which is then available for plant use. The type of symbiotic rhizobia is …
Rhizobium - an overview | ScienceDirect Topics
网页Rhizobia are a diverse group of Gram-negative, nodule-forming bacteria known for inhabiting the rhizosphere and establishing mutual symbiotic relationship with leguminous plants.
Diversity of Rhizobia and Importance of Their Interactions with …
网页2020年5月24日 · Both the rhizobia–host specificity and the diversity of the native rhizobia community are fundamental for the efficient use of inoculants. Poor inoculation responses may be related to large and diverse indigenous populations of …
