A new species of Ranunculus (Ranunculaceae) from Western Pamir-Alay, Uzbekistan

Abstract

New data on the phylogeny of four rare and endemic species of Ranunculus L. sect. Ranunculastrum DC. of western Pamir-Alai, one of which is new to science, have been obtained. Ranunculus tojibaevii sp. nov., from the Baysuntau Mountains, Western Hissar Range of Uzbekistan, is described. The new species is closely related to R. botschantzevii Ovcz., R. convexiusculus Kovalevsk. and R. alpigenus Kom., but differs in the blade of the radical leaves, which is rounded-reniform, segments 3–5-dissected, each 2–5-partite with elongated, rounded apical lobes. A phylogenetic analysis, using both the nuclear ribosomal internal transcribed spacer (ITS) and cpDNA (matK, rbcL, trnL-trnF), was informative in placing R. tojibaevii in context with its most closely-related species. Discussion on the geographic distribution, updated identification key, a detailed description, insights about its habitat and illustrations are provided.

Comparative Analyses of Chloroplast Genome Provide Effective Molecular Markers for Species and Cultivar Identification in Bougainvillea

“…Especially, trnH-psbA has been a popular and efficient DNA barcode for taxonomic studies [25,26]. Other than trnH-psbA, the intergenic trnL-trnF has also been commonly used for analysis of phylogenetic relationships in Ranunculaceae [27] and Rubiaceae [21]. However, the combination of trnH-psbA, trnL-trnF, and trnL intron could not sufficiently explain interspecific discrepancies in Bougainvillea (Figure S1).…”

Identification of Lamiaceae species in the flora of Uzbekistan using DNA markers

“…Современная систематика дикорастущих растений в Узбекистане использует преимущественно классические методы ботаники; базируясь на сравнении морфо-анатомических признаках и кариологических данных, проводится естественная классификация таксонов, отражающая их филогенетическую историю (Sennikov et al, 2016). В настоящее время отечественные исследования с использованием генетических методов для идентификации видов, прояснения эволюционных взаимоотношений, а также оценка генетического разнообразия дикой флоры Узбекистана немногочисленны (Juramurodov et al, 2021;Shchegoleva et al, 2022). Семейство Lamiaceae Martinov является космополитом, включая в себя более 7800 видов, образующих 245 родов (The Plant List URL: http://www.theplantlist.org/1.1/browse/A/Lamiaceae/).…”
