“…The absence of inoculation with R. tropici provided the highest leaf contents of N (9 %), P (11%), and Ca (15%) ( Table 2). Contrarily to what was verified by Abdiev et al (2019) with chickpea, with the highest contents of N, P, and K on roots and leaves when in the presence of inoculation.…”

Studies related to nitrogen fertilization and biological nitrogen fixation in the increase of chickpea production are considered scarce in tropical regions. This work aimed to evaluate the inoculation with Rhizobium tropici, and nitrogen fertilization, under irrigated tropical conditions, on the development of chickpea in low and high content of soil organic matter (SOM). The experimental design was in randomized blocks, with four replications, in a 2 x 6 factorial scheme. Treatments, consisted of the presence and absence of inoculation with R. tropici, and six N doses (0, 25, 50, 75, 100, and 125 kg ha-1) in the form of urea. The study was divided into two areas with distinct contents of SOM. In the area with the lowest content of SOM (3.55 dag kg-1), the inoculation with R. tropici or the fertilization with 125 kg ha-1 N increased the leaf content of nutrients (N, K, Mg, and P) and grain mass per plant, 100-grain mass, number of pods with two grains, dry mass of leaves, branches, chlorophyll index, and relative agronomic efficiency. Thus, the yield was increased in 65%, compared to the control treatment, recommending the application of 100 to 125 kg ha-1 of N with or without R. tropici. In the area with the highest content of SOM (7.37 dag kg-1), the inoculation with R. tropici provided a higher grain mass per plants, number of pods with one gain, dry mass of leaves, total dry mass, and chlorophyll index; nitrogen fertilization increased the leaf content of N and the chlorophyll index, although neither factor interfered with the yield, and are not recommended. Such results indicate the dependence of the nitrogen fertilization and inoculation with Rhizobium on the natural availability of N in the SOM.

“…However, nitrogen fertilization did not interfere with the contents of Ca, with a mean of 8.42 g kg -1 ( Figure 3B), and reduced the leaf contents of Na in the treatment with R. tropici ( Figure 3D). Indicating the attenuation of sodium in the plant caused by inoculation (Abdiev et al, 2019).…”

“…Along with pH, salt concentration also affects the growth of microbial strain on a large scale. Sometimes, the symbiosis process between the rhizobial and its host plant enables it to tolerate the salt concentration to a large extent (Abdiev et al, 2019 ). In the present study, it is observed that MB-17a showed optimum growth up to 100 mM salt concentration, but after a high salt concentration, i.e., from 200 to 400 mM, its growth decreases with an increase in salt concentration ( Figure 2A ).…”

Plant growth-promoting rhizobacteria (PGPR) are root endophytic bacteria used for growth promotion, and they have broader applications in enhancing specific crop yield as a whole. In the present study, we have explored the potential of Rhizobium pusense MB-17a as an endophytic bacterium isolated from the roots of the mung bean (Vigna radiata) plant. Furthermore, this bacterium was sequenced and assembled to reveal its genomic potential associated with plant growth-promoting traits. Interestingly, the root endophyte R. pusense MB-17a showed all essential PGPR traits which were determined by biochemical and PGPR tests. It was noted that this root endophytic bacterium significantly produced siderophores, indole acetic acid (IAA), ammonia, and ACC deaminase and efficiently solubilized phosphate. The maximum IAA and ammonia produced were observed to be 110.5 and 81 μg/ml, respectively. Moreover, the PGPR potential of this endophytic bacterium was also confirmed by a pot experiment for mung bean (V. radiata), whose results show a substantial increase in the plant's fresh weight by 76.1% and dry weight by 76.5% on the 60th day after inoculation of R. pusense MB-17a. Also, there is a significant enhancement in the nodule number by 66.1% and nodule fresh weight by 162% at 45th day after inoculation with 100% field capacity after the inoculation of R. pusense MB-17a. Besides this, the functional genomic annotation of R. pusense MB-17a determined the presence of different proteins and transporters that are responsible for its stress tolerance and its plant growth-promoting properties. It was concluded that the unique presence of genes like rpoH, otsAB, and clpB enhances the symbiosis process during adverse conditions in this endophyte. Through Rapid Annotation using Subsystem Technology (RAST) analysis, the key genes involved in the production of siderophores, volatile compounds, indoles, nitrogenases, and amino acids were also predicted. In conclusion, the strain described in this study gives a novel idea of using such type of endophytes for improving plant growth-promoting traits under different stress conditions for sustainable agriculture.

“…In addition, they can increase nutrient (mainly P and Fe) availability in the root zone (Chebotar et al 2001;Argaw 2012), inhibit phytopathogens (Tavares et al 2018) and modify rhizosphere chemicals, such as ethylene (Nascimento et al 2018). The use of NER can significantly increase the ability of rhizobia resident in soil to form nodules, fix N and increase growth in soybean, Glycine max (Dashti et al 1998), mung bean (Shaharoona et al 2006), chickpea, Cicer arietinum (Abdiev et al 2019) and common bean (Chihaoui et al 2015). Likewise, the use of a NER, Azospirillum brasilense, inoculated in combination with elite rhizobial strains can increase nodulation and amount of fixed N derived from symbiosis in soybean (Hungria et al 2015), common bean, Phaseolus vulgaris (Remans et al 2008) and lentil, Lens culinaris (Tsigie et al 2011).…”

Nitrogen fixation is an important biological process in terrestrial ecosystems and for global crop production. Legume nodulation and N 2 fixation have been improved using nodule-enhancing rhizobacteria (NER) under both regular and stressed conditions. The positive effect of NER on legume-rhizobia symbiosis can be facilitated by plant growth-promoting (PGP) mechanisms, some of which remain to be identified. NER that produce aminocyclopropane-1carboxylic acid deaminase and indole acetic acid enhance the legume-rhizobia symbiosis through (i) enhancing the nodule induction, (ii) improving the competitiveness of rhizobia for nodulation, (iii) prolonging functional nodules by suppressing nodule senescence and (iv) upregulating genes associated with legume-rhizobia symbiosis. The means by which these processes enhance the legume-rhizobia symbiosis is the focus of this review. A better understanding of the mechanisms by which PGP rhizobacteria operate, and how they can be altered, will provide opportunities to enhance legume-rhizobial interactions, to provide new advances in plant growth promotion and N 2 fixation. Highlights • ACC deaminase and IAA synthesis enhance nodule formation. • ACC deaminase and IAA synthesis improve the competitiveness of rhizobia for nodule induction. • IAA synthesis enhances N 2 fixation by upregulating the expression of genes associated with legume-rhizobia symbioses. • ACC deaminase prolongs nodule function by delaying nodule senescence. • ACC deaminase can reduce the negative influence of very high IAA on nodule induction.
