Abstract
For the first time, the morphological and anatomical structure of vegetative and generative organs, the localization of secretory ducts in the underground and aboveground parts of the species plants were studied. New GIS technologies were used to elucidate the spatial structure of the rare endemic species Komarovia anisosperma of the monotypic genus Komarovia Korovin of the Apiaceae family. The performed analysis showed the most significant diagnostic features of the studied organs, such as a deep taproot system, the presence of a multi-branched caudex, underdeveloped stem leaves or stem leaves reduced to sheaths, the central cylinder of the main root showing separate concentric circles of large and small vascular bundles, the presence of numerous secretory ducts in the secondary root cortex, strongly elongated palisade leaf cells etc. As a result of phytochemical study, extracts of Komarovia anisosperma roots and inflorescences were analyzed. According to our data, the main component of underground organs from terpenes was α-muurolene, and for inflorescences it was α-curcumene. Grid mapping showed that the species is mainly concentrated in the Samarkand and Kashkadarya regions, where the most favorable conditions for its growth are found. These areas are the natural area of origin of the species, and the establishment of a protected natural area has led to an increase in the number of natural populations.
