Krasnovia
''Krasnovia'' is a monotypic genus of flowering plant in the family Apiaceae. Its only described species is ''Krasnovia longiloba'', native to Kazakhstan, Kyrgyzstan and Xinjiang. The genus was first described in 1950, and was named after Andrei Krasnov by M.G. Popov. The species was first described in 1842 as ''Sphallerocarpus longilobus''. A 2001 study using ribosomal DNA found that '' Neoconopodium'', ''Krasnovia'' and ''Kozlovia'' were closely related within tribe Scandiceae subtribe Scandicinae, and proposed that they be combined into '' Kozlovia''. , this proposal had been accepted by the Germplasm Resources Information Network, but not by Plants of the World Online Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew.

Neoconopodium
''Neoconopodium'' is a genus of flowering plant in the family Apiaceae, native to Pakistan and the western Himalayas. It may be subsumed into the genus '' Kozlovia''. Taxonomy The genus was first described in 1987 by M. G. Pimenov and E. V. Kljuyko. They treated a subgeneric taxon of '' Conopodium'', ''Neoconopodium'', first described by Boris Koso-Poljansky in 1916, as the basionym. Their genus ''Neoconopodium'' was distinguished from '' Anthriscus'', ''Chaerophyllum'', ''Krasnovia'' and ''Butinia'' (now included in ''Conopodium'') based on seed characters. A 2001 study using ribosomal DNA found that ''Neoconopodium'', ''Krasnovia'' and '' Kozlovia'' were closely related within tribe Scandiceae subtribe Scandicinae, and proposed that they be combined into ''Kozlovia''. , this proposal had been accepted by the Germplasm Resources Information Network, but not by Plants of the World Online Plants of the World Online (POWO) is an online database published by the Royal Bot ...

Andrei Krasnov
Andrei Nikolaevich Krasnov (Андрея Николаевич Краснов, 27 October 1862 – 19 December 1914) was a Russian botanist who explored the plants of Turkestan, Altai, Nizhny Novgorod, Tian Shan and the Caucasus regions. He was a professor at the University of Kharkov. His major contribution was in phytogeography, identifying combinations of species found in different regions and contributing to the study of global vegetation patterns and their links to the Köppen climate classification. Life and work Krasnov was born in a Don Cossack family in St. Petersburg. His brother Pyotr became a noted General. He went to the St Petersburg Gymnasium before joining St Petersburg University where he studied under V. V. Dokuchaev and A.N. Beketov. A contemporary was V. I. Vernadsky. He took an interest in geography, soils, and the distributions of plants. In 1883, he joined on an expedition into the Nizhny Novgorod region. This was followed by other regions during whic ...

Apioideae
This is a list of genera belonging to the family Apiaceae. It contains all the genera accepted by Plants of the World Online (PoWO) . A few extra genus names are included that PoWO regards as synonyms. Unless otherwise indicated, the placement of genera into sub-taxa is based on the taxonomy used by the Germplasm Resources Information Network (GRIN). "Not assigned" means either that the genus is unplaced in GRIN or that it is not listed by GRIN. Not assigned to a subfamily In a 2021 molecular phylogenetic study, the ''Platysace'' clade and the genera ''Klotzschia'' and ''Hermas'' fell outside the four subfamilies. It has been suggested that they could be placed in subfamilies of their own. *''Hermas'' L. *''Klotzschia'' Cham. *''Platysace'' Bunge ;Others Subfamily Apioideae Subfamily Azorelloideae Subfamily Mackinlayoideae Subfamily Saniculoideae The NCBI Taxonomy Browser lists the tribes Saniculeae and Steganotaenieae in a separate subfamily, Saniculoide ...

Kozlovia
''Kozlovia'' is a genus of flowering plants belonging to the family Apiaceae. Its native range is Afghanistan to Central Asia ( Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) and Pakistan.. Taxonomy The genus name ''Kozlovia'' is in honour of Pyotr Kozlov (1863–1935), a Russian and Soviet traveller and explorer who continued the studies of Nikolai Przhevalsky in Mongolia and Tibet. The genus was first described in 1904. A 2001 study using ribosomal DNA found that ''Neoconopodium'', ''Krasnovia'' and ''Kozlovia'' were closely related within tribe Scandiceae subtribe Scandicinae, and proposed that they be combined into ''Kozlovia''. , this proposal had been accepted by the Germplasm Resources Information Network, but not by Plants of the World Online Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew.

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Ribosomal DNA
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments. In the human genome there are 5 chromosomes with nucleolus organizer regions: the acrocentric chromosomes 13 (RNR1), 14 ( RNR2), 15 ( RNR3), 21 (RNR4) and 22 (RNR5). The genes that are responsible for encoding the various sub-units of rRNA are located across multiple chromosomes in humans. But the genes that encode for rRNA are highly conserved across the domains, with only the copy numbers involved for the genes having varying numbers per species. In Bacteria, Archaea, and chloroplasts the rRNA is composed of different (smaller) units, the large (23S) ribosomal RNA, 16S ribosomal RNA and 5S rRNA. The 16S rRNA is widely used for phylogenetic studies. Eukaryotes The rRNA transcribed from the approximately 600 rDNA repeats forms the most abundant section of RNA found in cells ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
