A Model for the Development of the Rhizobial and Arbuscular Mycorrhizal Symbioses in Legumes and Its Use to Understand the Roles of Ethylene in the Establishment of these two Symbioses [PDF]

open access: yes, 2002
We propose a model depicting the development of nodulation and arbuscular mycorrhizae. Both processes are dissected into many steps, using Pisum sativum L. nodulation mutants as a guideline. For nodulation, we distinguish two main developmental programs,

Wild Cicer species exhibit superior leaf photosynthetic phosphorus‐ and water‐use efficiencies compared with cultivated chickpea under low‐phosphorus conditions

open access: yesNew Phytologist, Volume 247, Issue 1, Page 144-159, July 2025.
Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven

Decoding Long‐Distance Communication Under Mineral Stress: Advances in Vascular Signalling and Molecular Tools for Plant Resilience

open access: yesPlant, Cell &Environment, Volume 48, Issue 7, Page 4781-4802, July 2025.
ABSTRACT Mineral nutrients are essential for plant growth, development and crop yield. Under mineral deficient conditions, plants rely on a sophisticated network of signalling pathways to coordinate their molecular, physiological, and morphological responses.

Cyclic β-glucans at the bacteria–host cells interphase: One sugar ring to rule them all [PDF]

open access: yes, 2018
Cyclic β‐1,2‐D‐glucans (CβG) are natural bionanopolymers present in the periplasmic space of many Proteobacteria. These molecules are sugar rings made of 17 to 25 D‐glucose units linked exclusively by β‐1,2‐glycosidic bonds.

Structural and productive responses of signalgrass and its association with leaf area index and light interception under silvopastoral or monoculture systems

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Silvopastoral systems (SPSs) have emerged as one of the most prominent alternatives for grassland recovery. We evaluated the structural and productive responses of signalgrass [Urochloa decumbens (Stapf.) R. D. Webster] and its association with leaf area index (LAI) and light interception (LI) measured with different equipment across different

Nodule Initiation Elicited by Noninfective Mutants of \u3cem\u3eRhizobium phaseoli\u3c/em\u3e [PDF]

open access: yes, 1985
Rhizobium phaseoli CE106, CE110, and CE115, originally derived by transposon mutagenesis (Noel et al., J. Bacteriol. 158:149-155, 1984), induced the formation of uninfected root nodule-like swellings on bean (Phaseolus vulgaris).

Diversity of Sinorhizobium meliloti from the Central Asian Alfalfa Gene Center [PDF]

open access: yes, 2002
Sinorhizobium meliloti was isolated from nodules and soil from western Tajikistan, a center of diversity of the host plants (Medicago, Melilotus, and Trigonella species).

Modulation of rhizosphere microbiota by Bacillus subtilis R31 enhances long‐term suppression of banana Fusarium wilt

open access: yesiMetaOmics, Volume 2, Issue 2, June 2025.
This study indicated that biocontrol bacterium B. subtilis R31 is likely to prevent and control banana Fusarium wilt through regulating the structure and function of banana rhizosphere microorganism flora (especially increasing the microbial abundance of Actinomyces), and help potential biocontrol bacteria grow into the plant roots.

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
