SUMMARYPlant interactions with arbuscular mycorrhizal fungi have long attracted interest for their potential to promote more efficient use of mineral resources in agriculture. Their widespread use, however, remains limited by understanding of the processes that determine the outcome of the symbiosis. In this study, variation in growth response to mycorrhizal inoculation was characterized in a panel of diverse maize lines.A panel of thirty maize lines was evaluated with and without inoculation with arbuscular mycorrhizal fungi. The line Oh43 was identified to show superior response and, along with five other reference lines, was characterized in greater detail in a split-compartment system, using 33P to quantify mycorrhizal phosphorus uptake.Changes in relative growth between non-inoculated and inoculated plants indicated variation in host capacity to profit from the symbiosis. Shoot phosphate content, abundance of intra-radical and root-external fungal structures, mycorrhizal phosphorus uptake, and accumulation of transcripts encoding plant PHT1 family phosphate transporters varied among lines.Larger growth responses in Oh43 were correlated with extensive development of root-external hyphae, accumulation of specific Pht1 transcripts and a high level of mycorrhizal phosphorus uptake. The data indicate that host genetic factors influence fungal growth strategy with an impact on plant performance.

Mycorrhizal Plants

Arbuscular mycorrhizal fungi (AMF) are obligate symbionts of higher plants which increase the growth and nutrient uptake of host plants. The primary objective was initiated based on analyzing the enormity of optimal effects upon AMF inoculation in a comparative bias between mycorrhizal and non-mycorrhizal plants stipulated on plant biomass and nutrient uptake. Consequently, in accomplishing the above-mentioned objective a vast literature was collected, analyzed, and evaluated to establish a weighted meta-analysis irrespective of AMF species, plant species, family and functional group, and experimental conditions in the context of beneficial effects of AMF. I found a significant increase in the shoot, root, and total biomass by 36.3%, 28.5%, and, 29.7%, respectively. Moreover, mycorrhizal plants significantly increased phosphorus, nitrogen, and potassium uptake by 36.3%, 22.1%, and 18.5%, respectively. Affirmatively upon cross-verification studies, plant growth parameters intensification was accredited to AMF (Rhizophagus fasciculatus followed by Funniliforme mosseae), plants (Triticum aestivum followed by Solanum lycopersicum), and plant functional groups (dicot, herbs, and perennial) were the additional vital important significant predictor variables of plant growth responses. Therefore, the meta-analysis concluded that the emancipated prominent root characteristics, increased morphological traits that eventually help the host plants for efficient phosphorus uptake, thereby enhancing plant biomass. The present analysis can be rationalized for any plant stress and assessment of any microbial agent that contributes to plant growth promotion.

Background: Plant growth promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) are an alternative for sustainable management of pepper crops. Objective: To investigate the beneficial effects of PGPR and AMF inoculation on the growth of bell pepper plants. Methods: Two PGPR strains were used (Pseudomonas tolaasii P61 and Bacillus pumilus R44) as well as their mixture, and an uninoculated control. In addition, bacterial treatments were combined with an AMF-consortium (Funneliformis aff. geosporum and Claroideoglomus sp.). A 4×2 factorial experiment [four levels for the bacterial inoculation and two levels of AMF-inoculation (non-AMF and AMF)] was performed with eight treatments, at greenhouse conditions for 80 days after inoculation. AMF inoculation was done at sowing and PGPR after 15 days of seedling emergence. Results and Conclusions: Uninoculated control showed lower growth responses than plants inoculated with PGPR and AMF, alone or in combination. Overall, inoculation of the strain P61 or the combination of R44+AMF increased plant growth. AMF improved the photochemical efficiency of PSII in comparison to either control plants or plants inoculated with R44 or with the bacterial mix. Both PGPR and AMF improved growth and vigor of bell pepper plants.
