Ítem Acceso Abierto Aislamiento y caractrización molecular de hongos (ecto y endo) micorrizicos asociados al cultivo de maíz (Zea mays L.) en el bosque seco del sur del país(Universidad Católica de Cuenca., 2023) Galarza Riera, Christian Andres; Salazar Orellana, Marjorie Jazmín; 0105846596This research aimed to evaluate the diversity of fungi in the rhizospheric soil of maize grown under different agricultural practices in the Pindal canton, Loja province, Ecuador. Soil and root samples were collected from two experimental sites under the three agricultural practices: planting, urea application, and burning. The samples were analyzed by molecular techniques to identify the presence of fungi. The results indicated that the rhizospheric soil of the two experimental sites showed a high fungi diversity. A total of seven fungal species were identified in the soil and 28 fungal species in the maize root. Metagenomic analysis of the soil revealed seven bacterial classes, 16 fungal families, and four species of mycorrhizal fungi. The functions of the fungi present in the root and soil were classified into 15 groups. The composition of the fungal community colonizing the rhizospheric soil varied according to agricultural practices. The rhizospheric soil of the dry forest had a higher diversity of fungi than the rhizospheric soil of the experimental sites with agricultural management. Finally, soil chemical and physical properties varied according to agricultural practices. The results demonstrate that the rhizospheric soil of the corn crop is a complex environment with a high diversity of fungi. Agricultural practices can affect the composition of the fungal community, colonizing the rhizospheric soil, which can impact on crop yield and quality. Keywords: microbial community, mycorrhizae, metagenomics, agricultural practices.
