The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

mLife, EarlyView.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Genetic diversity and community structure of rhizobia nodulating Sesbania cannabina in saline-alkaline soils

, 2016
Sesbania cannabina is a plant that grows naturally along the seashores in Rudong County, China (RDC) and it has been introduced into the Yellow River Delta (YRD) as a pioneer plant to improve the saline-alkaline soils.

Suppression of soil microbiota rather than neighbours facilitates absinthe Artemisia absinthium invasion in native grasslands

Oikos, EarlyView.
Many mechanisms can lead to successful plant invasion, but their importance is often context dependent. One such mechanism is allelopathy: chemical inhibition of neighbouring plants. The importance of allelopathy may be mediated by soil microbiota and environmental conditions, and depend upon the species or functional group affected.

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

Plant biostimulants and their potential role in achieving the United Nations sustainable development goals

PLANTS, PEOPLE, PLANET, EarlyView.
Plant biostimulants are substances that are obtained from a variety of sources and are applied in minute quantities to enhance plant growth and vigor. In this review we detail how the use of plant biostimulants may contribute to efforts to achieving a number of the UN Sustainable Development Goals.

Harnessing Rhizobia to Improve Heavy-Metal Phytoremediation by Legumes [PDF]

, 2018
Rhizobia are bacteria that can form symbiotic associations with plants of the Fabaceae family, during which they reduce atmospheric di-nitrogen to ammonia.

Endosymbiotic bacteria nodulating a new endemic lupine Lupinus mariae-josephi from alkaline soils in Eastern Spain represent a new lineage within the Bradyrhizobium genus

, 2011
Lupinus mariae-josephi is a recently described endemic Lupinus species from a small area in Eastern Spain where it thrives in soils with active lime and high pH. The L.

Breeding for multi‐stress resilience in crops: Myth or possibility?

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change threatens millions of farmers worldwide by exposing crops to multiple concurrent or sequential environmental stresses such as drought, heat, waterlogging, and diseases. Although crops have long been selected under naturally occurring multi‐stress conditions, breeding pipelines largely focus on optimal or single‐stress environments ...

Biochemical analysis of induced resistance in chickpea against broomrape (Orobanche foetida) by rhizobia inoculation

Phytopathologia Mediterranea, 2016
This study examined the capacity of Rhizobium sp. strain PchAZM to reduce parasitism of chickpea by Orobanche foetida under greenhouse conditions, and assessed the relative impact of rhizobia on the expression of chickpea defense response against ...

Challenges and limitations of introducing pigeonpea as a new crop into smallholder farming systems through farmer‐to‐farmer education in Zambia

PLANTS, PEOPLE, PLANET, EarlyView.
Legume plants offer generous benefits for both the planet and people by supporting sustainable farming, food and feed systems through their ability to symbiotically fix atmospheric nitrogen. While grain legumes are cultivated and consumed globally, their adoption, market development, and integration into cropping systems vary.
