Large-scale excavation for extracting bioactive compounds from the plants in arid regions of Xinjiang over the last few years has, however, significandy decreased their distributions. Due to the urgent need for preservation of these plant resources, along with the need of searching for alternative source of the useful metabolites, it is important to screen the endophytic microbial resources associated with the plant Ferula sinkiangensis K. M. Shen. In the study, a total of 125 endophytic bacteria belonging to 3 phyla, 13 orders, 23 families, and 29 genera were isolated based on 16S rRNA gene sequencing data. Among the different isolates, three strains isolated from roots were potential novel species of the genera Porphyrobacter, Paracoccus and draycofatopsis. In this study, 79.4% and 57.1% of the total isolates were capable of producing indole-3-acetic acid （IAA） and siderophore, respectively. And, 40.6% of the strains inhibit the growth of fungal pathogen Afternaria alternata, 17.2% and 20.2% strains were positive for antagonism against Vertidllium dahlia 991 and V. dahlia 7, respectively. These results demonstrated that E sinkiangensis is a rich reservoir of endophytic bacterial resources with potential for production of biologically important functions such as plant growth-promoting factors.展开更多

Our research was carried out on the territory of Navoi region. The article presents an ecological analysis of the species of the Ferula L. in Navoi region. The species of genus Ferula mostly grows in mountainous regions and some are distributed in arid climates. According to that 15 species of the genus were found in the Navoi region, most of these species are considered to be plants that contain tar as well as have a strong medicinal property. In various parts of the world, different species of Ferula have been used in traditional medicine. In the course of studies, it was found that the species has medicinal, essential-oil, honey-juicy, nutritious, and fodder properties. According to ecological analysis, the genus Ferula grows Rocky, gravelly, fine-grained slopes and ridges of mountains, scree, rocks, outcrops of variegated rocks, rocky slopes, sandy, clay and gravelly deserts, foothill plains, fine-grained slopes. Considered rare, Ferula kyzylkumica Korovin is listed in the Red Book of the Republic of Uzbekistan, while Ferula nuratavica Pimenov is an endemic plant of the Aktau ridge.展开更多
