“…Aunque en nuestro caso se muestrearon tres puntos, estos representan muestras mezcladas de cinco plantas en el campo agrícola, por lo que sugerimos que con 15 muestras estamos estudiando la diversidad de especies de HMA del lote. Los valores en número de esporas son considerablemente bajos (de 8 a 17.35 esporas en 50 g de suelo, normalizado a 50 g de suelo), en comparación con un trabajo reportado para suelos donde se ha cultivado maíz (175 a 300 esporas en 50 g de suelo; Londoño et al, 2020). Otro trabajo, realizado por Oehl et al (2003) mostró que la población de esporas en monocultivos de maíz puede oscilar entre 125 y 400 esporas en 50 g de suelo.…”

Antecedentes: Las plantas voluntarias se consideran un problema en suelos de cultivo como posible reservorio de enfermedades, pero también de diversidad de microorganismos. Plantas micotróficas como el maíz permitirían preservar inóculos micorrízicos. La zona de preservación ecológica La Uba, en Guasave, Sinaloa, es un relicto de vegetación de selva baja caducifolia y su microbiota ha sido poco estudiada. Esta región ha sido reconvertida a suelo agrícola, por lo que estudiamos una zona de transición aledaña. Objetivo: Establecer la diversidad de hongos micorrízicos arbusculares (HMA) presentes en rizósfera y raíces de plantas voluntarias de maíz en una zona de transición contigua a La Uba. Métodos: Se colectaron raíces de maíz de plantas voluntarias y suelo una vez, entre ciclos agrícolas en una zona de transición. Se extrajo ADN genómico de raíces colonizadas con HMA y esporas del suelo, se amplificó y se secuenció masivamente el ITS del ADN ribosomal. Resultados y conclusiones: Se encontraron un total de 12 especies de HMA, pertenecientes a los géneros Glomus, Rhizophagus, Funneliformis y Gigaspora; siendo Glomus el más abundante. Glomus indicum se reporta por primera vez en México. Las plantas voluntarias de maíz pueden servir como reservorio de inóculo de HMA en suelos agrícolas.

“…Mycorrhizal association is a symbiotic association of some fungal species (including ectomycorrhizae and endomycorrhizae) with plant roots . The most common endomycorrhizal group is the arbuscular mycorrhizal fungi (AMF) that use arbuscules and vesicles for the transportation and storage of plant nutrients . In these mutual relations, the plant offers photosynthates (up to 20%) to the fungus (AMF), while AMF provide the plant with macronutrients, particularly phosphates .…”

Pulses are considered a remarkable and stable source of nutrients, which are being presently extensively cultivated and consumed in different parts of the world. Pulses belong to the family Leguminosae and are a rich source of nutrients such as phosphorus (P) and nitrogen (N) for best growth via symbiotic relationship with bacteria and AMF (arbuscular mycorrhizal fungi). The aim of the current study was evaluating the influence of AMF diversity associated with various pulses (French bean, mung bean, kidney bean, peas, soybean, peanuts, and grams). Furthermore, AMF characterization was done using morphological features of spores and sequencing of the rDNA gene, which confirmed the existence of 10 different AMF taxa. Among the different genera, the genus Glomus was observed to be the most dominant with 30% species followed by Gigaspora (22%), Sclerocystis (12%), Acaulospora (8%), Rhizophagus and Septoglomus (7%), Diversispora (5%), and Claroideoglomus, Archaeospora, and Ambispora (3%). Furthermore, soil physicochemical analysis and percentage of AMF colonization results revealed the fact that the phosphorus content (inversely proportional to the AMF diversity) was a determining factor of AMF diversity. The highest amount of available phosphorus (62.825 mg kg −1 ) in the district Swabi resulted in a low rate of AMF colonization (6.66 ± 11.54%) with a comparatively higher rate of AMF colonization (50.66 ± 1.15%) found in the soil of the district Chitral having a low phosphorus content (17.3 ± 7.6 mg kg −1 ). Nutrient uptake by pulses including nitrogen (2.4 ± 1.3%), phosphorus (13.5 ± 7.6 mg kg −1 ), potassium (99.5 ± 25.8 mg kg −1 ), zinc (1.4 ± 0.5 mg kg −1 ), moisture (2.3 ± 1.3%), crude fats (5.6 ± 2.8%), ash (4 ± 1.2%), and proteins (13.6 ± 9.01%) determined the fact that AMF species diversity is positively correlated to the plant mineral nutrition. From the current study, it is concluded that AMF inoculation to the soil fields is beneficial to ensure the sustainability and productivity of pulse crops in diverse environmental conditions without polluting the soil.

“…On the other hand, a well-known symbiotic association on the earth is found between plants and the Arbuscular mycorrhizal fungi (AMF) [16], which has proven to be beneficial for the plants as it provides plants with a nutrient-rich environment, mainly consisting of phosphate [17,18], while the other partner plant provides the carbohydrates to the symbiotic relationship partners, i.e., AMF, which they synthesize during photosynthesis [19,20]. In addition, some species of rice called transgenic species contain genes to resist the pests' release of some secretions into the soil microbiome that contains a special protein which is exclusively related to pesticides [21,22]. In return, AMF contain a special mycelium that permits the transfer of C-products during photosynthesis to the soil microbiome.…”

“…Meanwhile, the growth of the plant is enhanced due to its beneficial association with AMF. Thus, due to this increase in growth, the hyphae present in the soil absorb the maximum amount of nutrients [18][19][20][21][22][23][24][25]. Interconnected hyphae around the roots of a plant are reported to harm the roots of the nearby plant [26,27].…”

Plant Growth Promoting Rhizobacteria (PGPR) and Arbuscular Mycorrhizal Fungi Combined Application Reveals Enhanced Soil Fertility and Rice Production

et al. 2023

Rice (Oryza sativa L.) is an important crop that is grown worldwide to supply the world’s expanding food demand. In the current study, the effects of plant growth-promoting rhizobacteria (PGPR) and Arbuscular mycorrhizal fungi (AMF) on soil fertility and rice growth were explored. Rice plants were inoculated to evaluate how AMF fungi and PGPR affect various aspects of soil and plants, implicating abiotic stress tolerances. The experiment was carried out in a completely randomized design with three replicates under the controlled conditions. Results depicted that the plants that were inoculated with a mixture of AMF and PGPR had better yields and nutritional concentrations, while both AMF and PGPR lowered soil pH and organic matter differently. Similarly, AMF and PGPR treatments significantly increased the amount of N, P, K, and B in the post-harvest soil. The PGPR-inoculated plants had a 10–40% higher buildup of N in their tissues. Similarly, when they were compared with non-infected plants, AMF-inoculated treatments demonstrated a greater N accumulation in the rice tissue. The maximum P content in plant tissues was 0.149% in PGPR5-infected plants, either alone or in combination with AMF. In T12, AMF + PGPR5 inoculated rice plants, the maximum K uptake was 1.98%, which was 54% higher than the control treatment. The sole application of AMF raised K buildup in rice tissues by 38% compared with the control treatment. The improved productivity of plants with AMF and PGPR (especially with PGPR5) was attributed to the increased availability of nutrients in the soil. As a result, rice plant growth, yield, and essential element uptakes were boosted significantly. The present study’s results suggested using the combined application of AMF + PGPR5 for improving the rice yield and for sustaining the soil health.
