The strigolactone biosynthesis gene DWARF27 is co-opted in rhizobium symbiosis

BMC Plant Biology, 2015
BackgroundStrigolactones are a class of plant hormones whose biosynthesis is activated in response to phosphate starvation. This involves several enzymes, including the carotenoid cleavage dioxygenases 7 (CCD7) and CCD8 and the carotenoid isomerase ...

Rhizobium brockwellii sp. nov., Rhizobium johnstonii sp. nov. and Rhizobium beringeri sp. nov., three genospecies within the Rhizobium leguminosarum species complex

International Journal of Systematic and Evolutionary Microbiology, 2023
Genomic evidence indicates that the Rhizobium leguminosarum species complex comprises multiple distinct species, perhaps 18 or more. Of the five earliest genospecies (gs) to be described, only two have formal names: R. leguminosarum sensu stricto (gsE) and

Rhizobium anhuiense sp. nov., isolated from effective nodules of Vicia faba and Pisum sativum.

International Journal of Systematic and Evolutionary Microbiology, 2015
Four rhizobia-like strains, isolated from root nodules of Pisum sativum and Vicia faba grown in Anhui and Jiangxi Provinces of China, were grouped into the genus Rhizobium but were distinct from all recognized species of the genus Rhizobium by ...

Saprophytic Intracellular Rhizobia in Alfalfa Nodules

Molecular Plant-Microbe Interactions, 2000
In indeterminate alfalfa nodules, the establishment of the senescent zone IV, in which both symbionts undergo simultaneous degeneration, has been considered, until now, as the end point of the symbiotic interaction. However, we now describe an additional

Natural Regeneration After Volcanic Eruptions: Resilience of the Non-legume Nitrogen-Fixing Tree Parasponia rigida

Frontiers in Forests and Global Change, 2020
Volcanic eruptions disturb vegetation at a time it is needed for preventing mudflows. A resilient indigenous non-legume nitrogen-fixing tree that is adapted to the ash and spreads rapidly protects areas downstream in a volcanic landscape in Indonesia ...

Rhizobium sophorae sp. nov. and Rhizobium sophoriradicis sp. nov., nitrogen-fixing rhizobial symbionts of the medicinal legume Sophora flavescens.

International Journal of Systematic and Evolutionary Microbiology, 2015
Five bacterial strains representing 45 isolates originated from root nodules of the medicinal legume Sophora flavescens were defined as two novel groups in the genus Rhizobium based on their phylogenetic relationships estimated from 16S rRNA genes and ...

Lentils can Absorb Amino Acids as a Nitrogen Source Supporting Early Growth

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Lentils (Lens culinaris Medik.) are a valuable crop due to their high nutritional content, low environmental impact, and nitrogen‐fixing ability via rhizobacteria. Early in development, before this symbiosis is established, lentils require external nitrogen, typically supplied through fertilizers or already present in soils.
