Wild relatives of fruit plants are an important reserve for introducing certain properties and traits into cultivated plants that significantly expand the range and facilitate the possibility of their use, since many wild species are sources of useful properties and traits that are poorly expressed or absent in cultivated species and varieties. One of these types is undoubtedly the Maaka.

The article substantiates the scientific basis for the protection of wild relatives of cultivated plants in Karakalpakstan. According to the classification, 10 species (or 5, 8%) were included in the category of rare species. These are representatives of 7 families from 9 genera. The category of species whose range is declining includes 9 species from 7 families and 9 genera. Micro-foci of maximum concentration of DSCR were identified, and it was proposed to create 5 more OPTs in them. It is also proposed to declare the populations of Malacocarpus crithmifolius (Retz) C.A. Mey., Amygdalus spinossisima Bunge and Ammodendron longiracemosum Raik as natural monuments.

In The Wild

The performance of three wild relatives of the cultivated tomato (Lycopersicon cheesmanii, L. peruvianum and Solanum pennellii) and two tomato cultivars in control and saline media was compared. The parameters studied were elongation rate of the main stem, succulence, and accumulation of Na+, K+, and Cl- in the roots, stem, leaf, and shoot tip. The same parameters but in the leaf only were also studied comparatively in two of the wild species L. cheesmanii and S. pennellii, the same two cultivars, and F1 hybrids. Under control conditions, the elongation rate of the stem of the two cultivars was higher than that of the wild plants, but under salinity it was relatively lower. Among all species, S. pennellii was the most succulent in all its major parts under both control and saline conditions. The wild species, especially S. pennellii, showed high accumulation of Na+ in the leaf and top and a greater decrease in K+ content under salinity as compared with the cultivated plants. In all three species, Na+ probably substitutes for potassium in, at least, some of its physiological functions. Complete dominance of S. pennellii over the cultivated plants is indicated for the relative decrease of elongation rate and K+ level and for the increase of succulence under salinity. In contrast, L. cheesmanii seems to be completely dominant only for the relative decrease of K+ under salinity.

There is a need to scientifically validate the claim that wild species of medicinal plants are more potent than the cultivated plants. Thus, this study evaluated the phytochemical and antioxidant properties of wild and cultivated Alepidea amatymbica. Acetone, methanol, and water extracts of the rhizome of wild and cultivated A. amatymbica were evaluated for total phenol, flavonol, flavonoid, tannin, proanthocyanidin, saponin, and alkaloid contents using spectrophotometric methods. In vitro antioxidant activity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS), ferric reducing antioxidant power (FRAP), nitric oxide (NO), and hydrogen peroxide assays. The wild extracts had higher phytochemical contents in most of the assays than cultivated extracts. Total phenol in the wild extracts ranged from 32.30 to 117.8 mg GAE/g with the acetone extracts having the highest content while the water extracts were the least. The range in the total phenol of the cultivated species was 66.46 to 98.44 mg GAE/g with the methanol extracts having the highest content while water extracts was the least. The flavonoid content ranged from 55.01 to 99.09 mg QE/g and from 48.65 to 67.32 mg QE/g for the wild and cultivated plants, respectively. The alkaloid contents ranged from 14.70 to 17.80% in the wild species while it ranged from 11.98 to 13.21% in the cultivated species. The wild species also showed higher antioxidant activities in most of the assays evaluated. This study has implications for both pharmacological and conservation purposes.

SummaryWild relatives of tomato are a valuable source of natural variation in tomato breeding, as many can be hybridized to the cultivated species (Solanum lycopersicum). Several, including Solanum lycopersicoides, have been crossed to S. lycopersicum for the development of ordered introgression lines (ILs). Despite the utility of these wild relatives and their associated ILs, limited finished genomes have been produced to aid genetic and genomic studies. We have generated a chromosome-scale genome assembly for Solanum lycopersicoides LA2951 using PacBio sequencing, Illumina, and Hi-C. We identified 37,938 genes based on Illumina and Isoseq and compared gene function to the available cultivated tomato genome resources, in addition to mapping the boundaries of the S. lycopersicoides introgressions in a set of cv. VF36 x LA2951 introgression lines (IL). The genome sequence and IL map will support the development of S. lycopersicoides as a model for studying fruit nutrient/quality, pathogen resistance, and environmental stress tolerance traits that we have identified in the IL population and are known to exist in S. lycopersicoides.

Researchers of the N.I.

Nomenclatural standards serve to confirm the authenticity of a cultivar and its name. They should be kept perpetually in the scientific herbarium collection. Herbarium specimens of nomenclatural standards are formatted in accordance with the recommendations of the International Code of Nomenclature for Cultivated Plants (ICNCP), registered in the VIR Herbarium Database and included in the Herbarium of Cultivated Plants of the World, Their Wild Relatives, and Weeds (WIR).

The genus Cichorium consists of two widely cultivated species C. intybus (chicory) and C. endivia (endive) and four wild species, C. bottae, C. spinosum, C. calvum, and C. pumilum. A multivariate and an UPGMA (unweighted pair group method average) analysis based on AFLP (amplified fragment length polymorphism) markers were used to establish the genetic relationships among the species and cultivar groups of C. intybus and C. endivia. At the species level, the results correspond with previously obtained phylogenetic relationships in that C. bottae is the most divergent species, and C. intybus and C. spinosum, as well as C. endivia, C. pumilum, and C. calvum formed clusters. Based on the congruence between phylogenetic and genetic analyses, unique markers were expected for all species, however, hardly any specific marker was found except for C. bottae. The analysis of cultivar groups of C. intybus resembled the species analysis in two respects: (i) grouping of cultivars according to cultivar groups, and (ii) lack of markers unique to cultivar groups. In contrast to C. intybus, the cultivar series of C. endivia do not form distinct groups, which would reflect that crosses have been made among the various cultivar groups. The relationships among Cichorium species and cultivars will be useful for setting up a core collection of Cichorium, and stress the importance of inclusion of the wild species in the collection.Key words: Cichorium, AFLP, diagnostic markers, cultivar relationships, genetic resources.
