Non-nodulating Agrobacterium-like strains identified among root nodule isolates of common bean were labeled with gusA, a reporter gene encoding beta-glucuronidase (GUS). Bean plants were then co-inoculated with an infective Rhizobium strain and labeled transconjugants of Agrobacterium-like strains. Blue staining of nodules showed that Agrobacterium-like strains were able to colonize these symbi...

BACKGROUND: Bio-fertilizers are best eco-friendly approach for plant and soil environment. Also, micronutrient element such as iron plays a key role in the formation of chlorophyll and photosynthesis. OBJECTIVES: This study evaluated the effect of growth bacteria and Nano iron fertilizer and ordinary iron fertilizer on some physiological properties of Tritical...

in order to study the biological fixation efficiency of different strains of symbiosis bacteria in three varieties of common bean (phaseolus vulgaris l.) a factorial experiment based on randomized complete block design was conducted in zanjan province during 2006 and 2007. in this investigation three strains of rizobium including: rb117 (extracted from the zanjan soils), rb123 (extracted from t...

Legumes are considered to be an important component of subsistence cropping systems because of their ability to form nodules in symbiotic process with Rhizobium bacteria, which convert atmospheric nitrogen (N2) into assimilable form of ammonia, to add substantial amount of organic matter to the soil and to grow better than many other crops with low inputs under harsh climatic and edaphic condit...

The symbiotic association between root nodulating bacteria viz. Rhizobium and pulses enhance the crop agronomic characteristics, productivity quality depending upon effectiveness of bacterial strain. To evaluate this effectiveness, a study was conducted during December, 2019?April, 2020 (rabi) at Central Farm Odisha University Agriculture Technology, Bhubaneswar- 751003, aimed evaluating effici...

Morphological changes that take place in peat cultures of several species of rhizobia were examined. These changes seemed to be associated with enhanced survival of cells in peat and after inoculation onto plastic beads, which were used as a model system for seeds. Cell wall changes, in which the periplasmic space appeared to be occluded with electron-dense material, were observed in Rhizobium ...

Double inoculation (15 h apart) of the soybean cultivar Williams with Bradyrhizobium japonicum I-110ARS reveals a rapid regulatory plant response that inhibits nodulation of distal portions of the primary root (M Pierce, WD Bauer 1984 Plant Physiol 73: 286-290). Only living, homologous rhizobia elicit the response. We conducted similar double inoculation experiments to test the hypothesis that ...

To study the influence of rhizobium inoculation on growth and yield of groundnut (Arachis hypogaea) cultivars, an experiment was conducted at Kurram Agency, Pakistan during 2007. The rhizobium inoculation significantly enhanced the growth and yield parameters of groundnut cultivars. However, the maximum plant height (88.43 cm), number of shoots (19.9 plant), number of leaves (173.27 plant), num...

Background: Indigenous rhizobial populations may be unable to achieve successful symbiosis in the field due rare population and unfavourable soil environment. Introduced plant growth promoting rhizobacteria (PGPR) are frequently linked faster growth, development, yield of with synergetic effect on indigenous Rhizobium bacteria. Furthermore, co-inoculating legumes both PGPR is proven more effect...

abstract arsenic (as) contamination of soils is a global problem. legumes are often used in remediation of contaminated sites because of their capacity to fix nitrogen. in the present study, the effects of inoculation of bean (by rhizobium leguminosarum bv. phaseoli) on plant uptake and tolerance to arsenic were investigated. an experiment with a factorial arrangement, two levels of inoculation...
