“…The genus Glomus was represented in all the soils collected in the two study sites. This distribution of the genus Glomus is comparable to previous observations made in Cameroon (Ngonkeu et al, 2013, in Brazil (Samba-Mbaye et al, 2020Teixeira et al, 2017;Vieira et al, 2020), Morocco (Sellal et al, 2016) and China (Song et al, 2019). The predominance of species of the genus Glomus in all sites suggests a better adaptation of this genus either to the most hostile conditions such as drought, salinity and other environmental stresses (Blaszkowski et al, 2018), or to a wide range of ecological niches (Houngnandan et al, 2009).…”

The papaya tree is not very exploitable on the international market because of the post-harvest decline of the fruits. In this study, we identified arbuscular mycorrhizal fungi (AMF) from the rhizosphere of papaya in two agroecological zones of Cameroon (Njombe-Pendja: NP and Yaounde: Y). Morphological studies on the density, the rate of root colonization, the diversity of AMF species were evaluated. Molecular identification of AMF was performed by sequencing the small subunit (SSU) 18S rDNA gene region from soil samples. These genes were amplified from the AML and NS2 primers. The total number of spores per 100 g of dry soil was significantly different (P<0.05) depending on the sites, ranging from 391 in NP to 790 in Y sites. The frequency and intensity of root colonization was not significantly different in the two sites. Eleven (11) AMF belonging to seven (7) genera (Scutellospora, Gigaspora, Acaulospora, Entrophospora, Funneliformis, Glomus and Racocetra) were recorded. Two AMF species (T1: Scutellospora rosa and T6: Racocetra gregaria) were recorded at NP and absent at Y. The Shannon-Wiener index revealed a low diversity of AMF species. Homogeneity of species was recorded. Molecular analysis reveals that the AMF species obtained have sizes of 250 bp.

“…All the results obtained at the end of the current study suggest that the different arbuscular mycorrizal fungi inocula showed obviously their promoting effects on the symbiotic and physiological parameters of Argan seedlings after 8 months culture under nursery conditions. Indeed, Argan seedlings have been reported to be a very receptive species for arbuscular mycorrhizal fungi root colonization (Elmaati et al 2015;El mrabet et al 2014;Ouallal et al 2018;Sellal et al 2016). The analysis of the root system of inoculated seedlings had shown behavioral differences linked to different fungal isolates and complexes.…”

“…A significant enhancement of the growth parameters of the Argan seedlings in their early growth stage was observed for the different fungal inocula. The highest biomass production was observed in Argan seedlings inoculated with mycorrhizal complexes (El Mrabet et al 2014;Sellal et al 2016). These results were previously reported comparing the effects of complexes and fungal isolates (Caravaca et al 2003).…”

In semi-arid Mediterranean ecosystems, biotic and abiotic constraints have led to intense forest destruction and ecosystem deterioration and particularly to limitation in the production of Argan tree. Reforestation is thus more than ever a major challenge and an absolute necessity. The use of arbuscular mycorrhizal fungi (AMF) is of great importance in the processes of sustainable regeneration of the vegetation cover, given their roles in the improvement of plant growth and in the protection of soils. In the current study, Argan seedlings were inoculated with five arbuscular mycorrhizal fungi complexes and six arbuscular mycorrhizal fungi monospecific isolates. Growth, nutrition, photosynthetic pigments, and mycorrhizal colonization were under study. The soil samples were obtained from different ecosystems. Trap culture with Maize (Zea mays L.) was used for the production of mycorrhizal inoculum directly for complexes. Monospecific isolates were then produced from spore suspension using the technique of micropipette tips. Germinated seeds of Argan tree were inoculated separately with eleven fungal inoculants, under nursery conditions. Eight-month aged seedlings were compared for their growth and nutritional status. All the considered AMF inoculants stimulated significantly the growth of Argan seedlings; an increase in plant height between 33 and 70% was recorded. The aerial dry weight showed an increase of 62 to 124%, and the root dry weight showed an increase of 24 to 86% compared to the control. Similarly, the mineral contents in inoculated seedlings were significantly increased compared to the control non-inoculated seedlings. The analysis of the chlorophyll contents in leaves showed a significant improvement in inoculated seedlings. In conclusion, this first use of arbuscular mycorrhizal fungi isolates had shown that either complexes or monospecific isolates could improve significantly growth, mineral nutrition, and photosynthesis of Argan seedlings under nursery conditions. Hence, the use of inoculation with suitable consortium from these isolates is a recommended eco-friendly strategy for the restoration of degraded Argan ecosystems.

“…Given the drastic effect of climate change and anthropogenic factors, it is important to explore the fungal community of desert plant species, such as argan tree. This plant has strong and deep root system (Kenny & De Zborowski, 2007), which harbours high fungal diversity (Sellal, 2016). Previous focus had been paid to study fungal endophytes in arid and semi-arid habitats.…”

Current study identified endophytic fungi associated to Argania spinosa (argan) roots and revealed diverse haplotype diversity by the sequencing of internal transcribed spacer (ITS). 586 operational taxonomic units were identified and these operational taxonomic units (OTUs) could be assigned to fungal functional diversity such as endophytes, ectomycorrhiza and putative pathogens. Ascomycota phylum was abundant. Beside Ascomycota phylum, Basidiomycota members were also found in argan roots. Geopora, Sebacina, Knufia, Tomentella, Penicillim had high relative abundance. Our results highlighted a non-nested assemblage of fungi. Current non-nested findings also confirm that fungi have similar pattern found in other habitats. Pairwise analysis mirrored segregation pattern between same and different functional fungal group. Fungi in semi-arid conditions are non-randomly structured. Members of Ascomycota phylum had high Z-scores. This is the first molecular study conducted in arid and semi-arid habitats of Algeria aiming to identify fungi associated with roots in argan tree. Given the fact that deserts are among harsh environments and fungi associated to desert plants may have implications for biodiversity and ecosystem functioning.
