“…Автори висловлюють припущення, що поспішне укрупнення роду на основі лише молекулярних маркерів є наслідком відсутності надійного сучасного «таксономічного контексту», під яким розуміють коректний і стандартизований морфобіологічний (зокрема мікроморфологічний, цитоморфологічний та цитометричний) та цитогенетичний Журнал органічної та фармацевтичної хімії 2021, 19 (4) аналіз, що дасть можливість застосовувати до його результатів біоінформаційні обчислення та їх безпосереднє поєднання із молекулярнофілогенетичним аналізом. Для майбутньої молекулярної характеристики роду Iris, крім того, можна використовувати мікросателітні маркери, доповнені комбінацією пластидних маркерів [25]. Вивчення філогенетичних взаємозв'язків різних видів ірисів є досить складним через надзвичайну морфоекологічну різноманітність, значне поширення роду, множинні гібридизації та конвергентні процеси еволюції в роді [26][27][28].…”

Aim. To analyze and summarize literature data on the state of classification and taxonomy of Iris genus plants of Iridaceae family.Results and discussion. The genus Iris L. is one of the largest species of Iridaceae Juss family, which includes 1,800 species of 80 genera. Despite the fact that plants are very common as ornamental plants, there is currently no single classification for both horticultural and wild species of Iris genus. Various classifications and systems of irises have been proposed, the main difference between them is related to the understanding of the genus scope. The taxonomy of Iris genus underwent dramatic changes in the last century, especially in recent decades after the introduction of molecular methods. This paper deals with the analysis of current literature data on the existing classifications of Iris genus plants, the correspondence between taxonomic studies and the results of recent molecular studies. The data presented summarize the traditional classifications according to Rodionenko and Matthew, and also describe modern achievements in phylogenetic studies of this genus using functional genomic studies, involving molecular markers in irises. Conclusions. The data analyzed and summarized in the article can be useful for solving issues of taxonomy, phylogeny, genetics and practical problems of selection of plants of Iris genus; in addition, they will contribute to a more appropriate use of the Iris raw material in practical pharmacy.

Insights into genome size dynamics and its evolutionary impact remain limited by the lack of data for many plant groups. One of these is the genus Iris, of which only 53 out of c. 260 species have available genome sizes. In this study, we estimated the C-values for 41 species and subspecies of Iris mainly from the Eastern Mediterranean region. We constructed a phylogenetic framework to shed light on the distribution of genome sizes across subgenera and sections of Iris. Finally, we tested evolutionary models to explore the mode and tempo of genome size evolution during the radiation of section Oncocyclus. Iris as a whole displayed a great variety of C-values; however, they were unequally distributed across the subgenera and sections, suggesting that lineage-specific patterns of genome size diversification have taken place within the genus. The evolutionary model that best fitted our data was the speciational model, as changes in genome size appeared to be mainly associated with speciation events. These results suggest that genome size dynamics may have contributed to the radiation of Oncocyclus irises. In addition, our phylogenetic analysis provided evidence that supports the segregation of the Lebanese population currently attributed to Iris persica as a distinct species.

“…Iris sensu lato , a large genus within Iridaceae, as delineated by Mavrodiev et al. (2014) , comprises 260–300 species worldwide, which are distributed throughout the Northern Hemisphere ( Lawrence, 1953 ; Mathew, 1989 , 2000 ; Weber et al., 2020 ). While some Iris species naturally occur in mesic and wetland environments, the majority of species grow in arid, semi-arid, or dry montane environments ( Roguz et al., 2020 ).…”

The native populations of Iris hymenospatha and Iris histrio, two endangered bulbous species within the large Iris genus in Iridaceae, are threatened with extinction due to mining and other industrial activities in their natural habitats in Central Asia, including Iran. These species not only have a significant economic impact on the global horticultural industry due to their versatility and attractive phenotypic traits, but also have significant ecological value that necessitates their conservation. In this study, we examined the morphological and functional diversity between individuals within these two species, which exhibit high tolerance to environmental stresses. Our study examined 10 populations of I. hymenospatha and two populations of I. histrio based on bulb, flower, and leaf characteristics throughout Iran. We recognized a gradation of five different leaf shapes among I. hymenospatha populations with significant differences between some populations, including “Arak-Khomain” and “Arak-Gerdo”. The “Jaro”, “Natanz-Karkas”, “Ardestan-Taleghan”, “Arak-Rahjerd”, “Arak-Gerdo”, “Ganjnameh”, and “Abas-Abad” populations of I. hymenospatha displayed maximal values in leaf width, stem diameter under flower, crown diameter, flower number, leaf number, and bulb diameter. The I. histrio “Velian” population had a significantly larger flower size, a longer stem length, a larger style width, a longer flowering date, and a higher plant height compared to the “Ganjnameh” population of I. histrio. Such characteristics of both species make them remarkable ornamental plants. Our study also revealed that I. hymenospatha populations grow on different soils and elevations and have the ability to adapt to different growing conditions. Given the threats they face, conservation through horticultural selection and propagation offers a viable conservation strategy for both species. This approach not only preserves the genetic diversity of these species, but also enables their further contribution to the horticultural industry.
