Arbuscular mycorrhizal and dark septate fungal associations in shallot (Allium cepaL. var.aggregatum) under conventional agricultureWe examined roots of the shallot (Allium cepaL. var.aggregatum), one of the most popular cultivated crops of the family Aliaceae, cultivated under conventional agriculture for arbuscular mycorrhizal fungal (AMF) and dark septate fungal endophyte (DSE) associations. All the plants had dual colonization of both AMF and DSE associations. The intermediate-type AMF morphology in the shallot is the first report of this AMF type for the family Aliaceae. The extents of total AMF and DSE colonization ranged from 20.7 to 67.3% and 3.6 to 35.3% respectively and varied significantly among fields. Though no significant relationship existed between total AMF and DSE variables, they were correlated to the soil variables. Significant correlations existed between soil P and microscelerotia and also between soils N and K and AMF spore numbers. A total of six AMF spore morphotype belonging toGlomusandScutellosporawere identified.Scutellospora calosporawas the most dominant morphotype in the studied fields.

The application of  liquid compost and of beneficial soil microorganism such as arbsucular mycorrhizal fungi can be used to replace chemical fertilizer application. The aim of this study was to investigate the growth of red onion (Allium cepa L.) plant fertilized by liquid compost and  inoculated by arbuscular mycorrhizal fungi. This study was conducted based on a completely randomized design with two factors. The first factor was an addition of liquid compost dosages (0, 50, 100 and 200 ml/polybag). The second factor was an addition of AM fungal inoculum (with and without addition). The results showed that the growth of red onion plant was not significantly affected by the addition of liquid compost and AM fungal inoculum.  However,  the red onion plant fertilized by 200 ml liquid compost per polybag had the lowest shoot dry weight. The addition of AM fungal inoculum was not increasing plant growth because the quality of used inoculum was not good.

Arbuscular Mycorrhizal Fungal

Qatar is largely characterized by a hyper-arid climate and low soil fertility, which combine to create a stressful soil environment for arbuscular mycorrhizal (AM) fungi. Here we present a study on AM fungi communities and their relationship to soil chemical characteristics. We used high-throughput seqeuncing technique for identifying AM fungal diversity and community composition from different habitat types across Qatar. We found 127 AM fungal taxa, of which majority wee members of the family Glomeraceae. In contrast to what was hypothesized, AM fungi were mainly influenced by soil phosphorous and potassium. Chemical soil properties explained 76% of the variation in AM fungi between locations. The lowest AM fungal diversity was observed in barren areas and sand dunes, possibly due to low bioavailability of total nitrogen, while the highest diversity was observed in well-developed grass patches. Present AM fungi in Qatar were not affected by soil and pH; these fungi have likely been exposed to high salinities through their evolutionary history in the region, favoring resistant AM fungi through natural selection. These findings provide baseline information on AM fungal assemblages from the Arabian Peninsula, and thus contribute to better understanding of global patterns of AM fungi and their chemical drivers.

Root and rhizosphere soil samples were collected during the month of August,2017-March, 2018 from the surface to 20 cm depth as well as pH were also measured. Totally 25 plant species belonging to 19 families recovered Arbuscular mycorrhizal fungal spore and root colonization. The results of the present study arbuscular mycorrhizal spore population in the rhizosphere soil and rootcolonization of all the plant species. A total of 22 AM fungal species belonging to 7 genera and 2 different orders were recorded from the rhizosphere soil samples of this study region. The Glomus was dominant had seen in rhizosphere soil samples in all the medicinal plant species. The maximum spore population was found in the rhizosphere soil samples of Leucas aspera (470 /100 g soil) which belongs to the family Lamiaceae and lowest spore population was observed in the Tephorosia purpurea (123 /100g soil) belongs to Fabaceae. The highest 83 % AM fungal infection was found in roots of Achyranthus aspera belongs to the family Amaranthaceae, while the lowest 23 % AM fungal association was found in the root of Mimosa pudica belongs to the family Mimosaceae.
