Genome sequence of Ensifer arboris strain LMG 14919T: a microsymbiont of the legume Prosopis chilensis growing in Kosti, Sudan [PDF]

open access: yes, 2014
Ensifer arboris LMG 14919T is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of several species of legume trees.

Developmental Regulation of Nodule-Specific Genes in Alfalfa Root Nodules

open access: yesMolecular Plant-Microbe Interactions, 1988
We have cloned alfalfa nodule-specific cDNAs that code for leghemoglobin (Lb), glutamine synthetase (GS), and three unidentified nodulins. Hybrid-select translation of nodule RNA followed by 2-D gel electrophoresis showed that the Lb-specific cDNA corresponded to at least four Lb species of 12 kDa.

Tumor‐Derived Alpha‐1 Antitrypsin Promotes Liver Metastasis of Colorectal Cancer Through the Neutrophil Extracellular Traps–CCDC25 Pathway

open access: yesAdvanced Science, EarlyView.
ABSTRACT Liver metastasis is a leading cause of mortality in colorectal cancer (CRC), where the inflammatory tumor microenvironment, specifically neutrophil infiltration, significantly promotes metastatic colonization. This study reveals a pro‐metastatic role for alpha‐1 antitrypsin (A1AT) in CRC liver metastasis via a dual mechanism involving ...

Einfluss der Bewirtschaftung auf Nodulation von Erle und Robinie in Agroforststreifen [PDF]

open access: yes, 2017
Root nodules arise because of symbioses between higher plants and N2-fixing soil bacteria. Legumes and Rhizobium as well as actinorhizal plants and Frankia are known for their symbioses.

Ammonia Detoxification Inhibits Liver Metastasis by Reshaping Hepatic Microenvironment

open access: yesAdvanced Science, EarlyView.
Liver metastasis diverts aspartate into hyperactive pyrimidine synthesis, disrupting urea cycling and causing pathogenic ammonia accumulation. Ammonia dually reprograms the microenvironment by: (1) activating hepatic stellate cells (HSCs) into pro‐fibrotic metastasis‐associated fibroblasts (MAFs), and (2) suppressing anti‐tumor monocytes/macrophages ...

Cesium accumulation in nodules is involved in mitigating cesium transfer to shoot

open access: yesScientific Reports
Radiocesium (137Cs) transfer from soil to crops is largely regulated by soil potassium (K) levels owing to the chemical similarity between K and cesium (Cs).

MtMTP2-Facilitated Zinc Transport Into Intracellular Compartments Is Essential for Nodule Development in Medicago truncatula

open access: yesFrontiers in Plant Science, 2018
Zinc (Zn) is an essential nutrient for plants that is involved in almost every biological process. This includes symbiotic nitrogen fixation, a process carried out by endosymbiotic bacteria (rhizobia) living within differentiated plant cells of legume ...

DNA homology within the Rhizobiaceae : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University [PDF]

open access: yes, 1984
The relationship of rhizobia that nodulate Galega officinalis to the known species of Rhizobium and Bradyrhizobium was investigated. Similarly, the recently discovered fast­ growing soybean nodulating group of rhizobia was studied. Both groups were

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

open access: yesAdvanced Science, EarlyView.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...
