Botanica Pacifica plant chromosome data 1

Abstract

The chromosome numbers (2n) are presented for 82 vascular plant species of 61 genera from 31 families: Amaranthaceae: Amaranthus, Atriplex; Apiaceae: Angelica, Pimpinella, Torilis; Araceae: Calla; Asteraceae: Bidens, Hieracium, Lactuca, Leontodon, Solidago; Boraginaceae: Cerinthe, Lappula; Brassicaceae: Fibigia; Campanulaceae: Platycodon; Caryophyllaceae: Dianthus, Eremogone; Cupressaceae: Cupressus; Ericaceae: Rhododendron; Euphorbiaceae: Euphorbia; Fabaceae: Acacia, Astragalus, Galega, Lotus, Robinia, Trifolium, Vicia; Grossulariaceae: Ribes; Iridaceae: Iris; Lamiaceae: Leonurus, Lycopus; Liliaceae: Lilium; Nelumbonaceae: Nelumbo; Onagraceae: Chamaenerion; Orobanchaceae: Pedicularis; Paeoniaceae: Paeonia; Papaveraceae: Chelidonium, Glaucium, Papaver; Plantaginaceae: Plantago; Poaceae: Achnatherum, Calamagrostis, Digitaria, Eragrostis, Glyceria, Milium, Phleum, Poa, Puccinellia; Polygonaceae: Persicaria, Rumex; Primulaceae: Anagallis; Ranunculaceae: Delphinium, Pulsatilla; Rosaceae: Potentilla, Sibbaldia, Spiraea; Rubiaceae: Asperula; Urticaceae: Parietaria; Valerianaceae: Valeriana; Violaceae: Viola. The species studied are from East Europe (Ukraine), Siberia (Irkutsk Region, Novosibirsk Region, Republic of Buryatia), Caucasus (Abkhazia, Armenia, Azerbaijan, Georgia, Russia), Middle Asia (Kazakhstan, Kyrgyzstan, Turkmenistan, Uzbekistan) and the Russian Far East (Amur Region, Khabarovsk Territory, Primorye Territory). Most of the species are diploids, with different basic numbers (x). Species with variable ploidy also were revealed. The CN data are accompanied with the brief information on ecology and distribution of the species studied.

IAPT chromosome data 38

“…Two chromosome numbers are known for this species -2n = 18 and 2n = 36. The tetraploid number (2n = 36) was found in Russia: from the collection of the Botanical Garden of Moscow State University (a sample of unknown wild origin) (Oginuma & al., 2004), from Primorskii Krai (Polyakova & Muratova, 2015) and Irkutskaya Ob-lastʼ (Probatova & al., 2021). Our determination of the number of diploid chromosomes (2n = 2x = 18) from Eastern Siberia corresponds to the number of chromosomes previously established from Japan (Hara, 1952), which confirms the existence of two cytotypes (2x and 4x) within the species.…”

Chromosome numbers in some alien plant species of the Novosibirsk Region: post V

“…We continue the karyological study of adventive species in the flora of the Novosibirsk Region (An'kova, Zykova, 2020, 2021Zykova, Pankova, 2021;Zykova et al, 2022). In this paper, we present the results for 13 species found in the Novosibirsk Region.…”
