“…Representatives of the species here considered were first found in 1773 by S. G. Gmelin in Northern Iran (Gmelin, 1773) and classified by Carl Ludwig Hablitz as Pisum ochrus L. (Gmelin, 1774). The next finding was made by Н. Н. von Steven, who identified it as Orobus formosus (von Steven, 1812). In the first monographic summary of the Caucasus flora, Flora Tauricacaucasica, published between 1808 and 1819, von Steven's discovery was presented as such.…”

“…The analysis of the world's herbarium collections for the known localities of V. formosa made it possible to map 111 sites of its occurrence over the Main Caucasus Range and record sensu stricto the coordinates of the marginal points of its area of distribution in the Caucasus, together with its altitudinal boundaries, which varied from 2021 to 3500 MASL (Vishnyakova et al, 2015).…”

In the 1960s–1980s, the Vavilov Institute of Plant Industry, known worldwide as VIR, organized a substantial series of studies dedicated to a Caucasian endemic, the Pliocene relic Vavilovia formosa (Fabeae: Fabaceae). Those investigations are little known to the scientific community, although, in fact, the priority right for integrated research into this plant belongs to VIR. As a result of the cycle of studies, the first ideas about the biology and ecology of the species, the manner of its reproduction, its intraspecific diversity, the degree of crossability with other members of the tribe, its karyotype and anatomy were developed. The plants of V. formosa are not reproduced ex situ and their germplasm is absent in the world’s gene banks. Therefore, collecting V. formosa plants in their hard-to-reach habitats in the mountains is always crucial for research purposes, so a number of collecting expeditions were launched to the Greater Caucasus. The data thus obtained are discussed in the context of modern achievements in world science regarding this species.

“…Fed. is a small perennial herbaceous legume confined to highlands of the Caucasus and Anterior Asia (Davis, 1970;Vishnyakova et al, 2016). Although morphologically variable, it is traditionally considered the only member of the monotypic genus Vavilovia A. Fedorov.…”

“…The plastid and mitochondrial genomes of V. formosa are not available yet, in spite of explosive interest to this species in the recent decade (Akopian, Gabrielyan, 2008;Mikić et al, 2009Mikić et al, , 2013Mikić et al, , 2014Sinjushin et al, 2009;Akopian et al, 2010Akopian et al, , 2014Atlagić et al, 2010;Oskoueiyan et al, 2010;Sinjushin, Belyakova, 2010;ZemerskiŠkorić et al, 2010;Zorić et al, 2010;Vishnyakova et al, 2013Vishnyakova et al, , 2016Safronova et al, 2014Safronova et al, , 2015. This interest was motivated by V. formosa being although the most distant but still a pea crop wild relative, which may harbor some genes useful for pea prebreeding and somehow transferrable to pea.…”

The plastid and mitochondrial genomes of Vavilovia Formosa (Stev.) Fed. and the phylogeny of related legume genera

The plastid and mitochondrial genomes of Vavilovia formosa (Stev.) Fed. were assembled on the base of the data of high-throughput sequencing of DNA isolated from a sample from North Osetia, Russia, using Illumina and PacBio platforms. The long PacBio reads were sufficient for reliable assembling organellar genomes while the short Illumina reads obtained from total DNA were unacceptable for this purpose because of substantial contamination by nuclear sequences. The organellar genomes were circular DNA molecules; the genome of mitochondria was represented by two circular chromosomes. A phylogenetic analysis on the basis of plastid genomes available in public databases was performed for some representatives of the tribes Fabeae, Trifolieae and Cicereae. As was expected, the V. formosa branch proved to be sister to the Pisum branch, and the tribe Fabeae was monophyletic. The position of Trifolium L. appeared sensitive to the phylogeny reconstruction method, either clustering with Fabeae or with the genera Medicago L., Trigonella L. and Melilotus Mill., but the internodes between successive divergences were short in all cases, suggesting that the radiation of Trifolium, other Trifolieae and Fabeae was fast, occurring within a small time interval as compared to further evolution of these lineages. The data on the relatedness of the plastid genomes of Trifolium and Fabeae correlate with the similarity of N2-fixing symbionts in these legumes represented by Rhizobium leguminosarum biovars trifolii and viciae, while the symbionts of Medicago, Melilotus and Trigonella belong to the Sinorhizobium meliloti and S. medicae species, which are distant from Rhizobium.

“…The latter genus consists of a single species, Vavilovia formosa (Stev.) Fed., a relict and endangered legume plant, which grows mostly in high-mountain regions of the Caucasus and Middle East [12][13][14][15]. Based on genetic and morphological markers, Vavilovia is closely related to Pisum, such that it is still sometimes attribute to this genus [16].…”

Twenty-two rhizobia strains isolated from three distinct populations (North Ossetia, Dagestan, and Armenia) of a relict legume Vavilovia formosa were analysed to determine their position within Rhizobium leguminosarum biovar viciae (Rlv). These bacteria are described as symbionts of four plant genera Pisum, Vicia, Lathyrus, and Lens from the Fabeae tribe, of which Vavilovia is considered to be closest to its last common ancestor (LCA). In contrast to biovar viciae, bacteria from Rhizobium leguminosarum biovar trifolii (Rlt) inoculate plants from the Trifolieae tribe. Comparison of house-keeping (hkg: 16S rRNA, glnII, gltA, and dnaK) and symbiotic (sym: nodA, nodC, nodD, and nif H) genes of the symbionts of V. formosa with those of other Rlv and Rlt strains reveals a significant group separation, which was most pronounced for sym genes. A remarkable feature of the strains isolated from V. formosa was the presence of the nodX gene, which was commonly found in Rlv strains isolated from Afghanistan pea genotypes. Tube testing of different strains on nine plant species, including all genera from the Fabeae tribe, demonstrated that the strains from V. formosa nodulated the same cross inoculation group as the other Rlv strains. Comparison of nucleotide similarity in sym genes suggested that their diversification within sym-biotypes of Rlv was elicited by host plants. Contrariwise, that of hkg genes could be caused by either local adaptation to soil niches or by genetic drift. Long-term ecological isolation, genetic separation, and the ancestral position of V. formosa suggested that symbionts of V. formosa could be responsible for preserving ancestral genotypes of the Rlv biovar. may be traced using specialised symbiotic (sym) genes representing the accessory parts of bacterial genomes, which differ in their natural histories from housekeeping genes (hkg) representing the core parts of genomes [4]. As a result of co-evolutionary processes, symbiosis is formed between tightly co-adapted cross-inoculation groups of rhizobia and legumes, and their coevolution is directed by a set of symbiosis-specific genes from each partner [5][6][7]. In some rhizobia, sym genes are more susceptible to autonomous horizontal gene transfer than hkg genes, because they are located on plasmids-mobile elements of the genome [3]. This results in an intensive recombination of host specific and chromosomal markers [8]. For example, Rhizobium leguminosarum is composed of two biovars, which have diverged based on their plasmid-encoded host ranges [9]. Biovar viciae (Rlv) nodulates legumes from the Fabeae tribe, while biovar trifolii (Rlt) nodulates clovers from the Trifolieae tribe; however, they show a conservative chromosomal arrangement of hkg markers (Figure 1).Even so, divergent evolution of rhizobia is not restricted to sym genes. Application of the average nucleotide identity (ANI) method has demonstrated that a local R. leguminosarum population could be separated into five genomic species, differing in their hkg genes, representing their cor...
