Uncovering the reciprocal effects of plant polyploidy and the microbiome: implications for understanding of polyploid success

open access: yesNew Phytologist, Volume 247, Issue 3, Page 1060-1070, August 2025.
Summary Polyploidy plays a major role in diversification and speciation of almost all plants. Separately, the microbiome is recognized for its ubiquitous role in plant functioning. Despite the importance of both processes, we lack a synthetic picture of their reciprocal relationship.

Infection of Soybean and Pea Nodules by \u3cem\u3eRhizobium\u3c/em\u3e spp. Purine Auxotrophs in the Presence of 5-aminoimidazole-4-Carboxamide Riboside [PDF]

open access: yes, 1994
Purine auxotrophs of various Rhizobium species are symbiotically defective, usually unable to initiate or complete the infection process. Earlier studies demonstrated that, in the Rhizobium etli-bean symbiosis, infection by purine auxotrophs is partially

Concurrent anthropogenic stressors affect plant–soil systems with different plant diversity levels

open access: yesNew Phytologist, Volume 247, Issue 4, Page 1897-1911, August 2025.
Summary Plant diversity strongly influences ecosystem functioning. Due to human activities, ecosystems are increasingly threatened by the co‐occurrence of numerous anthropogenic pressures, but how they respond to this multifaceted phenomenon is poorly documented, and what role plant diversity plays in this process has not been investigated so far. Here,

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

open access: yes, 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

Unstable anthocyanin pigmentation in Streptocarpus sect. Saintpaulia (African violet) is due to transcriptional selectivity of a single MYB gene

open access: yesNew Phytologist, Volume 247, Issue 3, Page 1426-1444, August 2025.
Summary Saintpaulia (African violet) pigmentation is notoriously unstable and sometimes forms white stripes, particularly following passage through tissue culture. White‐striped petals were thought to be due to periclinal chimeras, but we confirmed that white stripes result from epigenetic regulation rather than periclinal chimeras based on the flower ...

Quinol Oxidase Encoded by \u3cem\u3ecyoABCD\u3c/em\u3e in \u3cem\u3eRhizobium etli\u3c/em\u3e CFN42 is Regulated by ActSR and is Crucial for Growth at Low pH or Low Iron Conditions [PDF]

open access: yes, 2015
Rhizobium etli aerobically respires with several terminal oxidases. The quinol oxidase (Cyo) encoded by cyoABCD is needed for efficient adaptation to low oxygen conditions and cyo transcription is upregulated at low oxygen. This study sought to determine
