Caballeronia is a genus of bacteria from the family of Burkholderiaceae [1] which has been reported to perform biological nitrogen fixation and promote plant growth [2] [3] [4] [5]
Caballeronia comprises the following species: [1] [6] [7]
An endophyte is an endosymbiont, often a bacterium or fungus, that lives within a plant for at least part of its life cycle without causing apparent disease. Endophytes are ubiquitous and have been found in all species of plants studied to date; however, most of the endophyte/plant relationships are not well understood. Some endophytes may enhance host growth and nutrient acquisition and improve the plant's ability to tolerate abiotic stresses, such as drought, and decrease biotic stresses by enhancing plant resistance to insects, pathogens and herbivores. Although endophytic bacteria and fungi are frequently studied, endophytic archaea are increasingly being considered for their role in plant growth promotion as part of the core microbiome of a plant.
The Burkholderiaceae are a family of bacteria included in the order Burkholderiales. It includes some pathogenic species, such as Burkholderia mallei (glanders) and Burkholderia pseudomallei (melioidosis). This family was found to be enriched in scale-eating pupfish guts, even after being fed a common laboratory diet, suggesting it may aid in scale-digestion.
Paenibacillus is a genus of facultative anaerobic, endospore-forming bacteria, originally included within the genus Bacillus and then reclassified as a separate genus in 1993. Bacteria belonging to this genus have been detected in a variety of environments, such as: soil, water, rhizosphere, vegetable matter, forage and insect larvae, as well as clinical samples. The name reflects: Latin paene means almost, so the paenibacilli are literally "almost bacilli". The genus includes P. larvae, which causes American foulbrood in honeybees, P. polymyxa, which is capable of fixing nitrogen, so is used in agriculture and horticulture, the Paenibacillus sp. JDR-2 which is a rich source of chemical agents for biotechnology applications, and pattern-forming strains such as P. vortex and P. dendritiformis discovered in the early 90s, which develop complex colonies with intricate architectures as shown in the pictures:
Pseudomonas migulae is a fluorescent, Gram-negative, rod-shaped bacterium isolated from natural mineral waters in France. This bacterium has also been isolated from endophytic tissues of lodgepole pine trees growing on gravel mining sites with potential to perform biological nitrogen fixation and plant growth promotion. Based on 16S rRNA analysis, P. migulae has been placed in the P. fluorescens group.
Caballeronia glathei is a Gram-negative soil bacterium. It is motile by using one polar flagellum.
Paraburkholderia phytofirmans is a species of bacteria. They have been reported to colonize endophytic tissues of hybrid spruce and lodgepole pine with a strong potential to perform biological nitrogen fixation and plant growth promotion.
Caballeronia sordidicola is a species of bacteria which has been reported to perform biological nitrogen fixation and promote plant growth
Caballeronia zhejiangensis is a Gram-negative, non-spore-forming, rod-shaped bacterium from the genus Caballeronia, which was isolated from a wastewater treatment system in China. Caballeronia zhejiangensis has the ability to degrade methyl parathion.
Caballeronia grimmiae is a gram-negative, non-spore-forming, rod-shaped bacterium from the genus of Caballeronia and the family of Burkholderiaceae which was isolated from the xerophilous moss Grimmia montana in China.
Caballeronia humi is a Gram-negative, aerobic, non-motile bacterium from the genus Burkholderia and the family Burkholderiaceae which was isolated from peat soil in Russia.
Caballeronia telluris is a bacterium from the genus Caballeronia and the family Burkholderiaceae.
Caballeronia terrestris is a bacterium from the genus Burkholderia and family Burkholderiaceae.
Caballeronia udeis is a bacterium from the genus Caballeronia and family Burkholderiaceae which has been reported to perform biological nitrogen fixation and promote plant growth
"Candidatus Caballeronia nigropunctata" is a Candidatus species of bacteria from the genus Caballeronia and the family Burkholderiaceae. "Candidatus Caballeronia nigropunctata" is an endosymbiont of the plant Psychotria nigropunctata.
Paraburkholderia insulsa is a Gram-negative, acidophilic, rod-shaped, arsenic-tolerant and aerobic bacterium from the genus of Burkholderia which has been isolated from the Ambitle Island on Papua New Guinea.
Paraburkholderia monticola is a Gram-negative, short-rod-shaped and aerobic bacterium from the genus Paraburkholderia which has been isolated from soil from the Gwanak Mountain in Korea.
Paraburkholderia rhizosphaerae is a bacterium from the genus of Paraburkholderia which has been isolated from rhizosphere soil in Daejeon in Korea.
Paraburkholderia susongensis is a Gram-negative bacterium from the genus Paraburkholderia which has been isolated from a weathered rock surface in Susong in the Anhui Province in China.
Paraburkholderia is a genus of Pseudomonadota that are gram negative, slightly curved rods that are motile by means of flagella. They have been reported to colonize endophytic tissues of hybrid spruce and lodgepole pine with a strong potential to perform biological nitrogen fixation and plant growth promotion. Unlike Burkholderia species, Paraburkholderia members are not commonly associated with human infection. Paraburkholderia members form a monophyletic clade within the Burkholderiaceae family, which is what prompted their distinction as a genus independent from Burkholderia species, in combination with the finding of robust conserved signature indels which are unique to Paraburkholderia species, and are lacking in members of the genus Burkholderia. These CSIs distinguish the genus from all other bacteria. Additionally, the CSIs that were found to be shared by Burkholderia species are absent in Paraburkholderia, providing evidence of separate lineages.
Caballeronia choica is a bacterium from the genus Caballeronia.
