Negotiation of mutualism: rhizobia and legumes [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2006 The evolution and persistence of biological cooperation have been an important puzzle in evolutionary theory. Here, we suggest a new approach based on bargaining theory to tackle the question. We present a mechanistic model for negotiation of benefits between a nitrogen-fixing nodule and a legume plant. To that end, we first derive growth rates for the

An experimental and modelling exploration of the host-sanction hypothesis in legume-rhizobia mutualism [PDF]
, 2008 Despite the importance of mutualism as a key ecological process, its persistence in nature is difficult to explain since the existence of exploitative, 'cheating' partners that could erode the interaction is common. By analogy with the proposed

HeliyonMicroorganisms associated with plant roots significantly impact the quality and quantity of plant defences. However, the bottom-up effects of soil microbes on the aboveground multitrophic interactions remain largely under studied. To address this gap, we

Short-term fertilizer application alters phenotypic traits of symbiotic nitrogen fixing bacteria [PDF]
PeerJ, 2015 Fertilizer application is a common anthropogenic alteration to terrestrial systems. Increased nutrient input can impact soil microbial diversity or function directly through altered soil environments, or indirectly through plant-microbe feedbacks, with ...

Frontiers in Sustainable Food Systems, 2021 Rhizobia are bacteria that exhibit both endophytic and free-living lifestyles. Endophytic rhizobial strains are widely known to infect leguminous host plants, while some do infect non-legumes.

MicroRNAs in the Rhizobia Legume Symbiosis [PDF]
Plant Physiology, 2009 Legumes are agronomically valuable crops for food and fodder production worldwide because they are rich in protein, oil, fiber, and micronutrients. In addition, legumes require less chemical fertilizer than other major crop plants since they can assimilate some nutrients through ...

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2018 Purpose: The purposes of this study were to characterise the migration and the colonisation dynamics of two different fluorescent-tagged rhizobia in various alfalfa tissues (especially in seeds); and also to develop efficient inoculation treatments to ...

Australia’s land of opportunity for horizontal gene transfer and symbiotic nitrogen fixation [PDF]
Microbiology AustraliaLegumes are plants that form symbioses with soil bacteria termed rhizobia, which convert (fix) atmospheric nitrogen (N2) into NH3. Symbiotic nitrogen fixation enhances crop and pasture legume growth and in Australia is worth an estimated A$4 billion per ...

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Biostimulants and related bioinputs encompass microbial and non‐microbial strategies used to improve plant performance, nutrient‐use efficiency, stress resilience, and soil functioning. Aim For this study, plant biostimulants were operationally defined as substances or microorganisms applied to enhance nutrient‐use efficiency ...
