There are only 10 validly characterized species in the genus Sinomonas, all of which are isolated from various soil types in Asia and have been reported as a result of useful biotechnological applications. Here we described the first report of the species Sinomonas halotolerans isolated from rhizospheric soil samples of Parkinsonia aculeata based on materials collected from the Sonoran Desert, Mexico. Parkinsonia aculeata is an indigenous species that has weathered salinity, drought, and extremely high temperatures in the semiarid parts of Mexico and contributes significantly to the functionality of these ecosystems through considerable rates of vegetation. Materials were collected three times, in February, March, and August 2022 in 2 locations: Bahia de Lobos and Tesopaco, affected by two abiotic stress conditions: salinity and drought respectively. During the investigation, the strains BA8A, BA10B, and TA1 were isolated from both locations, they were identified using microbiological and molecular techniques. Based on the 16S rRNA gene sequences, the three strains were identified as Sinomonas halotolerans (99.9% sequence similarity). As the genus Sinomonas is still poorly known in America, our study may help to improve this situation and S. halotolerans might be considered a potential species to develop novel biotechnological applications with the aim to cope with the adverse effects of salinity and drought in soil.
