“…The RI tends to promote the grain yield of leguminous crops by boosting root nodulation, which results in the higher fixation of atmospheric N through the BNF process [41]. Similar to our findings (sole RI and N fertilization in association with RI significantly promoted black gram nodulation), it was reported that RI proved to be an eco-friendly and cost-effective technique for boosting root nodulation in mung bean, peas, and red clover [42,43]. However, a previous study suggested that RI reduces the requirement of N fertilizer due to increased N fixation in many crops [44].…”

The potential interactions of rhizobium bacteria in enhancing nodulation, nitrogen (N) fixation for boosting N availability, and the yield of black gram under a temperate environment continue to remain unexplored. Therefore, this study aimed to evaluate the agronomic performance of black gram cultivars, their yield comparisons, and shoot–grain–soil N dynamics in a prevalently rainfed farming system. Two black gram cultivars, NARC Mash-I and NARC Mash-II, were subjected to rhizobia inoculation combined with different N doses (0, 25, 50, 75, 100 kg ha−1). The response variables included root nodulation, agronomic yield attributes, grain yield, shoot–grain and soil N dynamics, and biological productivity. Black gram cultivar NARC Mash-II showed the maximum nodule formation (41 per plant), while each nodule obtained 0.69 g weight in response to RI combined with 25 kg N ha−1. Additionally, this combination showed the highest pods per plant and thousand grain weight, which maximized the grain yield (1777 kg ha−1) and biological productivity (3007 kg ha−1). In contrast, NARC Mash-I under 50 kg N recorded the highest shoot N content, while the same cultivar under 100 kg N exhibited the maximum soil N content. The correlation analyses indicated a significantly robust association among the nodule numbers, grain weight, and N contents in different plant organs. These results give mechanistic insights into plant–microbe interactions based on the eco-friendly, sustainable, and smart agricultural practice of black gram production in a temperate environment.

“…In our study, lateral gene transfer of nifD was not effective as compared to Rhizobium species. The inoculation effect of Rhizobium species, especially Rhizobium trifolii, was studied individually and as coinoculation with other microbial inoculants on different clover varieties in various fields and climatic conditions [50][51][52][53][54]. Tufail et al [50] reported that inoculation of Rhizobium trifolii seed inoculation on berseem clover (Trifolium alexandrinum) significantly increased forage biomass and quality.…”

Livestock production in Afghanistan highly relies on grazing and clover feed, which is a key component of pastures and forage crops. This study elucidated the genetic diversity of clover-nodulating rhizobia in different ecological regions and their effects on clover growth. A total of 57 rhizobia were isolated and their genetic diversities were studied through 16S rRNA and nifD genes. The isolates were inoculated to clover (Afghan local variety), to investigate the potential of nitrogen fixation and influences of clover growth. The 16S rRNA gene analysis showed two distinct groups of Rhizobium (94.7%) and Ensifer (5.3%) species. The nifD phylogenetic relationship revealed a high similarity to Rhizobium and a novel lineage group close to Rhizobium leguminosarum species. In the plant test, different genotypes significantly (p < 0.01) exhibited an increase in plant biomass production, compared to the un-inoculated plants. Among genotypes, the highest plant biomass was recorded in PC8 (1769.0 mg/plant) and PC9 (1409.2 mg/plant) isolates as compared to un-inoculated plants (144.0 mg/plant). Moreover, these isolates showed maximum nitrogen fixation rates of 8.2 and 6.5 µM/plant, respectively. These isolates were identified as the most promising rhizobial strains for developing biofertilizers in the context of Afghanistan.

“…Moreover, the metabolism of xenobiotics often requires mobilization of the entire energy potential of the cell leading to reduction of plant growth and subsequent phytoremediation efficiency. It is also reflected by the ability of the defense system to resist attacks by phytopathogens [5,21]. Thanks to the development of transcriptomics and proteomics, it has been demonstrated that xenobiotic effects may involve not only biochemical and physiological disruption mainly related to oxidative stress but also the disruption of signaling pathways [87].…”

“…The first attempts to prove the validity of this approach have already been carried out, and endophytic bacteria with the potential to be used in microbe-assisted phytoremediation have been mostly acquired from plants grown on contaminated soils [7,16,17]. Some strains able to colonize plant tissues and degrade xenobiotics were also obtained from contaminated sediments and soils [18,19] and, what is less obvious, from plants grown on non-contaminated sites [20,21]. The most commonly isolated bacterial endophytes from those niches were assigned to the genera Pseudomonas, Bacillus, Burkholderia, Stenotrophomonas, Micrococcus, Pantoea, and Microbacterium.…”

Anthropogenic activities generate a high quantity of organic pollutants, which have an impact on human health and cause adverse environmental effects. Monitoring of many hazardous contaminations is subject to legal regulations, but some substances such as therapeutic agents, personal care products, hormones, and derivatives of common organic compounds are currently not included in these regulations. Classical methods of removal of organic pollutants involve economically challenging processes. In this regard, remediation with biological agents can be an alternative. For in situ decontamination, the plant-based approach called phytoremediation can be used. However, the main disadvantages of this method are the limited accumulation capacity of plants, sensitivity to the action of high concentrations of hazardous pollutants, and no possibility of using pollutants for growth. To overcome these drawbacks and additionally increase the efficiency of the process, an integrated technology of bacteria-assisted phytoremediation is being used recently. For the system to work, it is necessary to properly select partners, especially endophytes for specific plants, based on the knowledge of their metabolic abilities and plant colonization capacity. The best approach that allows broad recognition of all relationships occurring in a complex community of endophytic bacteria and its variability under the influence of various factors can be obtained using culture-independent techniques. However, for practical application, culture-based techniques have priority.
