“…The S57 strain was isolated following the procedure described by Muñoz et al [ 6 ] and is part of the plant-associated bacterial culture collection of the Laboratory of Plant Pathology and Bioproducts belonging to the Universidad de Tarapacá. This collection comprises one hundred eighty bacteria, which is functionally characterized for the bacterial PGP traits.…”

“…The 16S rRNA gene was amplified by PCR using bacteria-specific primers 27F and 1492R [ 34 ]. PCR reaction mix and PCR cycles were performed according to the procedure described by Muñoz et al [ 6 ]. Amplification reactions were performed using a VeritiTM 96-well Thermal Cycler (Thermo Fisher Scientific, Waltham, Massachusetts, USA).…”

“…Microbial communities associated to plant tissues (plant microbiome) are considered beneficial because they contribute to the plant by mitigating biotic and abiotic stress conditions [ 4 , 5 ]. Thus, this allow plants to survive under the extreme conditions that prevail in this region, including aridity, high concentrations of salts and boron, a wide thermal amplitude between the day and night, poor soil composition, and high UV radiation among other extreme environmental conditions which are restrictive for agricultural activities in arid and semiarid regions [ 6 , 7 ].…”

Oregano from Socoroma (Atacama Desert) is characterized by its unique organoleptic properties and distinctive flavor and it is produced using ancestral pesticide-free agricultural practices performed by the Aymara communities. The cultivation in this zone is carried out under extreme conditions where the standard production of different crops is limited by several environmental factors, including aridity, high concentration of salts, and boron among others. However, oregano plants are associated with microorganisms that mitigate biotic and abiotic stresses present in this site. In this work, the S57 strain (member of the Pseudomonas genus that is closely related to Pseudomonas lini) was isolated from roots of oregano plants, which are grown in soils with high content of non-sodium salts and aluminum. This bacterium stimulates the growth of Micro-Tom tomato plants irrigated with saline-boric water. Moreover, it controls the growth of phytopathogenic fungi Fusarium oxysporum and Botrytis cinerea and the nematode Meloidogyne incognita under saline-boric conditions. Together with the high levels of bacterial biomass (~47 g/L), these results allow the establishment of the bases for developing a potential new agricultural bioproduct useful for arid and semiarid environments where commercial biological products show erratic behavior.

“…However, some environments with the presence of water resources have allowed the development of wildlife and human settlement processes (Figure 2) (Muñoz and Choque 2013). The territory that comprises the Arica and Parinacota Region presents differences in the altitudinal gradient, distinguishing, from west to east, four ecological floors in a longitudinal way (Muñoz et al 2020). According to the description of this author, the ecological floors are the Coast, which is characterized by infrequent coastal plains and abrupt cliffs, with fresh watercourses of summer regime and some river mouths; the Desert Pampas, which has areas of extreme aridity, from the 500 meters of altitude, which are cut by hydrographic basins, significant from the point of view of biodiversity.…”

The Region of Arica and Parinacota is characterized as an agricultural region located in Atacama Desert at the extreme north of Chile. Its agriculture has allow developing the economy of pre-and post-Hispanic communities, which have been settled since colonial times at different locations in the region. This article is focused on how Aymara communities of Lluta Valley and Precordillera of Arica and Parinacota Region have been included as part of Chilean population, particularly, from social and economic point of view. Furthermore, a characterization of agronomic aspects of the main towns of this zone, and commercialization of agricultural and livestock is included. It must be considered that the evolution of this region would have an important impact in the safeguard on endemic flora and fauna so that it is imperative to protect the genetic heritage of local species and to promote new technologies which allow the production of commercial products from Arica and Parinacota Region.

“…The strong thermal oscillation is one of its distinctive characteristics due to its altitude. By virtue of the altitudinal differences, this vertical zoning of the territory promotes large biodiversity in the region, causing specific adaptive systems for the different ecosystems, both from the point of view of natural resources and from the anthropic perspective [5,6].…”
