Mutations in \u3cem\u3eRhizobium phaseoli\u3c/em\u3e that Lead to Arrested Development of Infection Threads [PDF]

, 1986
Two Rhizobium phaseoli mutants, isolated previously by Tn5 mutagenesis, elicited infection threads which ceased development prematurely, usually within root hairs. These infection threads were wide, globular, and otherwise altered in morphology, compared

Identification of ferredoxin II as a major calcium binding protein in the nitrogen-fixing symbiotic bacterium Mesorhizobium loti [PDF]

, 2015
BACKGROUND: Legumes establish with rhizobial bacteria a nitrogen-fixing symbiosis which is of the utmost importance for both plant nutrition and a sustainable agriculture.

De novo stolon organogenesis in potato leaf callus elicited by Agrobacterium tumefaciens stimulus

Journal of Integrative Plant Biology, EarlyView.
Agrobacterium tumefaciens triggers stolon regeneration from potato leaf callus independent of T‐DNA insertion, suggesting a strategy to reprogram callus identity and expand the potential of tissue regeneration. ABSTRACT Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves.

Effects of Soil Rhizobia and Drought on Plant–Vector–Pathogen Interactions on a Legume Host

Applied Sciences
Symbiosis between rhizobia and legumes can affect plant tolerance to abiotic and biotic stressors such as drought and herbivores. Yet few studies have assessed how soil rhizobia impact plants that face abiotic and biotic stress simultaneously.

Input of nitrogen from N2 fixation to northern grasslands [PDF]

, 2005
Forage legumes form N2-fixing symbioses with rhizobia and may thus make substantial contributions to the N pool in grasslands. However, to optimize their use as sources of N, it is important to elucidate the effects of management factors that influence ...

Phylogenies of atpD and recA support the small subunit rRNA-based classification of rhizobia [PDF]

, 2001
The current classification of the rhizobia (root-nodule symbionts) assigns them to six genera. It is strongly influenced by the small subunit (16S, SSU) rRNA molecular phylogeny, but such single-gene phylogenies may not reflect the evolution of the ...

Decoding stress resilience in soybean: Regulatory networks and precision breeding under climate change

Journal of Integrative Plant Biology, EarlyView.
This review covers recent progress in the understanding of stress‐responsive regulatory networks in soybean and highlights emerging genomic and breeding strategies. Integrating molecular insights and precision breeding will help to accelerate the development of climate‐resilient soybean cultivars.

Unraveling a Tangled Skein: Evolutionary Analysis of the Bacterial Gibberellin Biosynthetic Operon

mSphere, 2020
Gibberellin (GA) phytohormones are ubiquitous regulators of growth and developmental processes in vascular plants. The convergent evolution of GA production by plant-associated bacteria, including both symbiotic nitrogen-fixing rhizobia and ...

Cyclophilin A‐mediated cis/trans isomerization modulates RIN4 to control intracellular rhizobial infection in legumes

New Phytologist, EarlyView.
Summary In most legume‐rhizobium symbioses, rhizobial colonization occurs through host‐derived intracellular infection threads, which enable rhizobial recruitment while presumably modulating the host immune system to prevent rejection. To investigate post‐translational regulation of immune responses during rhizobial infection, we focused on Cyclophilin
