Desert plants, arbuscular mycorrhizal fungi and associated bacteria: Exploring the diversity and role of symbiosis under drought

Environmental Microbiology Reports, Год журнала: 2024, Номер 16(4)

Опубликована: Июль 9, 2024

Desert plants, such as Agave tequilana, A. salmiana and Myrtillocactus geometrizans, can survive harsh environmental conditions partly due to their symbiotic relationships with microorganisms, including arbuscular mycorrhizal fungi (AMF). Interestingly, some of these also harbour endosymbiotic bacteria. Our research focused on investigating the diversity AMFs associated bacteria in plants growing arid soil. We found that agaves have a threefold higher AMF colonization than M. geometrizans. Metabarcoding techniques revealed composition communities was primarily influenced by plant host, while bacterial were more affected specific compartment or niche they inhabited. identified both known novel endofungal taxa, Burkholderiales, confirmed presence within spores using multiphoton microscopy. study explored effects drought symbiosis between tequilana AMF. discovered severity could modulate strength this its outcomes for holobiont. Severe prevented formation symbiosis, moderate promoted it, thereby conferring tolerance tequilana.

Obesity is a critical medical condition worldwide that increasingly involved with nutritional derangements associated micronutrient deficiencies, including iron, zinc, calcium, magnesium, selenium, and vitamins A, C, D, E. Nutritional deficiencies in obesity are mainly caused by poor-quality diets, higher nutrient requirements, alterations metabolism, invasive treatments. The current conventional agricultural system designed for intensive food production, focusing on quantity rather than quality, consuming excessive inputs, producing nutrient-deficient foods, thus generating severe health environmental problems; products may worsen obesity-related malnutrition. Therefore, modern agriculture adopting new biofortification technologies to combat improve productivity sustainability. Biofertilization nanofertilization practices used due their efficiency, safety, reduced impact. Biofertilizers preparations of PGP-microorganisms promote plant growth influencing metabolism improving the uptake, nanofertilizers consist synthesized nanoparticles unique physicochemical properties capable increasing nutrition enriching products. This review presents obesity, unsustainable agri-food contributing progression, development bio- biofortifying crops micronutrients commonly deficient patients obesity.

Plant growth-promoting microorganisms (PGPM) benefit plant health by enhancing nutrient-use efficiency and protecting plants against biotic abiotic stresses. This study aimed to isolate characterize autochthonous PGPM from important agri-food crops nonagricultural formulate biofertilizers. Native were isolated evaluated for PGP traits (K, P, Zn solubilization, N2-fixation, NH3-, IAA siderophore production, antifungal activity Fusarium oxysporum). Isolates tested on radish broccoli seedlings, evaluating 19 individual isolates 12 microbial consortia. Potential bacteria identified through DNA sequencing. In total, 798 209 fungi isolated. showed higher mineral solubilization than other mechanisms; 399 156 presented solubilization. Bacteria relevant nitrogen fixation, siderophore, (29-176 mg/L), ammonia while growth inhibition (40-69%).

This study investigated the effects of arbuscular mycorrhizal fungi (AMF) on growth, phosphorus (P) uptake, and yield maize in presence or absence tillage. The two-year field experiment was conducted Kanagawa, Japan. Firstly, we whether indigenous AMF communities roots, as determined by amplicon sequencing analysis, contributed to growth Experiment 1, a 2-year field-based study. findings revealed that (Zea mays L.) rotary tillage had higher P at six-leaves collar stage, yield, compared no colonizing roots were altered tillage; specifically, increased dominance Gigasporaceae, whereas Acaulosporaceae.
