Considered to play an important role in plant mineral nutrition, arbuscular mycorrhizal (AM) symbiosis is a common relationship between the roots of a great majority of plant species and glomeromycotan fungi. Its effects on the plant host are highly context dependent, with the greatest benefits often observed in phosphorus (P)-limited environments. Mycorrhizal contribution to plant nitrogen (N)...

Abstract In this study, we investigated the interactive effects of arbuscular mycorrhizal fungus (AMF) Rhizophagus irregularis and soil bacteriomes on maize growth under salt stress (100 mM NaCl) also effect infection levels. We found that directly promoted indirectly enhanced biomass by increasing colonization levels, irrespective stress. Although R. itself had no growth-promoting even at a hi...

Abstract Microbial plant growth promoters (MPGP) are known to improve crop nutrition and root health. Here we examined the effects of individual combined inoculation chili pepper (variety Camino Real) with Rhizophagus irregularis (isolate BEG87) a commercial product Azospirillum brasilense on biocontrol against oomycete pathogen Phytophthora capsici CH11). In greenhouse pot experiment, unfertil...

Arbuscular mycorrhizal fungi (AMF), which form an ancient and widespread mutualistic symbiosis with plants, are a crucial but still enigmatic component of the plant micro biome. Nutrient exchange has probably been at the heart of the success of this plant-fungus interaction since the earliest days of plants on land. To characterize genes from the fungal partner involved in nutrient exchange, an...

The world potato is facing major economic losses due to disease pressure and environmental concerns regarding pesticides use. This work aims at addressing these two issues by isolating indigenous bacteria that can be integrated into pest management strategies. More than 2,800 strains of Bacillus-like and Pseudomonas-like were isolated from several soils and substrates associated with potato agr...

Arbuscular mycorrhizal fungi (AMF) are plant symbionts that promote growth and provide important ecosystem functions. These abilities have great economical potential which has resulted in an increasing number of commercially available AMF inoculants. Here, we present the results a global study evaluate effectiveness 28 commercial inoculants to colonize host plants under greenhouse field conditi...

Bark beetles play an important role as agents of natural renovation and regeneration in coniferous forests. Several studies have documented the metabolic capacity of bacteria associated with the gut, body surface, and oral secretions of these insects; however, little is known about how the bacterial community structure changes during the life cycle of the beetles. This study represents the firs...

Yam (Dioscorea alata) is a tropical plant that considered critical for food security. The use of high fertilizer, low soil fertility, and insect pest infestation reduce yam tuber yield quality. present study was performed to determine the effect potassium silicate arbuscular mycorrhizal fungi (AMF) on cultivated under salinity stress. This revealed combination Rhizophagus irregularis Potassium ...
