Requirement of a Plasmid-Encoded Catalase for Survival of \u3cem\u3eRhizobium etli\u3c/em\u3e CFN42 in a Polyphenol-Rich Environment [PDF]

open access: yes, 2008
Nitrogen-fixing bacteria collectively called rhizobia are adapted to live in polyphenol-rich environments. The mechanisms that allow these bacteria to overcome toxic concentrations of plant polyphenols have not been clearly elucidated.

Novel applications of the tomato microbiome: Roles and considerations for agriculture, human health, and society

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants, like humans, have a microbiome that helps them grow, defend themselves against pathogens, acquire nutrients, and protect themselves against environmental stresses. The microbiome of tomatoes, a staple crop grown worldwide, could be utilized not only to reduce fertilizer and pesticide applications, but also to clean up harmful pollutants ...

Dual mutualistic associations in sainfoin (Onobrychis viciifolia Scop.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Agronomy at Massey University [PDF]

open access: yes, 1982
Recent studies established that many legumes, when infected with the appropriate Rhizobium spp. and arbuscular fungi, nodulated better and exhibited greater dinitrogen fixation than plants infected with only the rhizobia.

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

open access: yesPLANTS, 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.

“I am a Scientist and I am a Science Teacher!”: Negotiating Shifts in Professional Identity

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT Pre‐service teachers often have limited opportunities to develop and reflect upon both their scientist and science teacher identities, and the relationships between them, likely limiting how they draw upon these different but complementary role identities in their teaching practice.

Determination of abundance and symbiotic effectiveness of native rhizobia nodulating soybean and other legumes in Rwanda

open access: yesPlant-Environment Interactions
Rhizobia diversity in the rhizosphere is one of the key promoters of biological nitrogen fixation between host legumes and microsymbionts, although related complex interaction may depend on various factors.

Diversity of nifH Gene in Culturable Rhizobia from Black Locust (Robinia pseudoacacia L.) Grown in Cadmium-Contaminated Soils

open access: yesBiology
(1) Background: Rhizobia can promote plant growth by providing essential nutrients such as NH4+ and PO43−; thus, rhizobia that can tolerate the stress of heavy metals will be conducive to the phytoremediation of heavy-metal-contaminated soils. Therefore,

Construction and utilisation of a bidirectional reporter vector in the analysis of two nod-boxes in of Rhizobium loti : a thesis presented in partial fulfilment of the requirements for the Degree of Master of Science in Molecular Genetics at Massey University [PDF]

open access: yes, 1993
The nod-box is a 47bp cis-acting regulatory region which has been conserved amongst every species of Rhizobium studied to date. In species such as R. meliloti and R.

Competitiveness and communication for effective inoculation byRhizobium, Bradyrhizobium and vesicular-arbuscular mycorrhiza fungi [PDF]

open access: yes, 1994
After a short summary on the ecology and rhizosphere biology of symbiotic bacteria and vesicular-arbuscular (VA) mycorrhiza fungi and their application as microbial inocula, results on competitiveness and communication are summarized. Stress factors such

Saprophytic Intracellular Rhizobia in Alfalfa Nodules [PDF]

open access: yesMolecular 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 zone, zone V, proximal to the senescent zone IV and present in alfalfa nodules more than 6 weeks ...
