Short-Term Cell Death in Tissues of Pulsatilla Vernalis Seeds From
www.nature.com/scientificreports OPEN Short‑term cell death in tissues of Pulsatilla vernalis seeds from natural and ex situ conserved populations Katarzyna M. Zielińska1*, Andrzej Kaźmierczak2 & Ewa Michalska1 Pulsatilla vernalis is a IUCN listed species that occurs in mountain and lowland habitats. The seeds collected from diferent populations are remarkably diverse in their viability depending on locality or year of collection. We aim to analyse seed viability, among others, by investigation of the percentage of alive, dying, and dead cells in embryos and endosperm when comparing the seeds from a wild lowland population and ex situ cultivation of plants of lowland and Alpine origin. The cell death was detected by staining with two fuorescence probes, one penetrating only the changed nuclear membranes, the other penetrating also the unchanged cells. 54.5% of Alpine origin seeds were presumably capable of germination if they were sown after collection, however, four months later only 36.4% had healthy embryos. In the case of lowland wild plants it was 31.8% and 18.2%, and from ex situ, 27.3% and 13.6%, respectively. 27.3% of Alpine origin seeds had embryo in torpedo stage (9.1% in the case of lowland seeds). Mean weight of the former was 2.9 mg (2.0 mg in lowland ones). Our results confrm the signifcance of seed origin and seed weight on viability, and that Pulsatilla seeds have a short ‘germination time window’. Pulsatilla vernalis (L.) Mill. (spring pasque-fower), also known as Anemone vernalis L. (Fig. 1), is a species strongly threatened with extinction in European Lowlands1–3. -
Pasque Flower
A Horticulture Information article from the Wisconsin Master Gardener website, posted 20 April 2007 Pasque Flower Pasque fl ower is one of the fi rst herbaceous perennials to bloom in spring. There are about 30 species in the genus Pulsatilla of the buttercup family (Ranunculaceae), but the most common one planted in gardens is the European pasque fl ower, Pulsatilla vulgaris. Pulsatilla is closely related to the genus Anemone; P. vulgaris was once classifi ed as A. pulsatilla and is still often listed under this name. Other common names include wind fl ower, meadow anemone, and Easter fl ower. P. vulgaris is Pasque fl ower is one of the earliest blooming perennials. native to dry meadows of central and northern continental Europe and the British Isles. It is hardy in zones 4-8. Although all parts of this plant are toxic and may cause stomach upset if ingested, it has been used medicinally for a variety of complaints – to treat infected sores, curing lameness from varicose veins, venereal disease and headaches. The plant has a thick and fi brous rootstock that becomes woody with age. The fi nely divided, stalked leaves emerge from this base in early spring, although the majority of the leaves develop after the fl owers. The leaves are pinnate, cleft to the base, forming a mound 10-12” tall. The entire plant is covered with soft, silvery Pasque fl ower is a low-growing plant. hairs. Plants remain attractive through the summer, although the leaves may die back in late summer. Upright, bell-shaped fl owers emerge shortly after the fi rst leaves. -

The Use of Microsatellites Markers in Molecular Characteristics of Hybrids Between Pulsatilla Species †
Proceeding Paper The Use of Microsatellites Markers in Molecular Characteristics of Hybrids between Pulsatilla Species † Kateryna Fyałkowska 1,*, Anna Tereba 1 and Grzegorz Łazarski 2 1 Department of Ecology, Forest Research Institute, Braci Leśnej 3 Street, PL 05-090 Sękocin Stary, Poland; [email protected] 2 Institute of Biological Sciences, Siedlce University of Natural Sciences and Humanities, Bolesława Prusa 14 Street, PL 08-110 Siedlce, Poland; [email protected] * Correspondence: [email protected] † Presented at the 1st International Electronic Conference on Forests—Forests for a Better Future: Sustainability, Innovation, Interdisciplinarity, 15–30 November 2020; Available online: https://iecf2020.sciforum.net. Abstract: Pulsatilla × hackelii Pohl. is the most common hybrid between Pulsatilla patens and Pulsa- tilla pratensis. It occurs in the natural environment, most often in sites together with parental forms. Pulsatilla × hackelii is morphologically intermediate between the pure Pulsatilla species. Separation of hybrid individuals from pure Pulsatilla species requires a whole set of morphological features. Completed plastid genome provides molecular evidence for the hybrid origin of Pulsatilla × hackelii. In our study, we present the—genotypic characteristics of Pulsatilla × hackelii based on microsatel- lite markers developed for Pulsatilla vulgaris. A specimen of the hybrid was found in the Świętokrzyskie Mountains, near Bocheniec village, in the vicinity of a forest road in a fresh mixed coniferous forest (Querco roboris-Pinetum (W. Mat. 1981) J. Mat. 1988). We amplified a set of 10 Citation: Fyałkowska, K.; Tereba, A.; microsatellites in two multiplex PCR reactions. From the 10 analyzed loci, we successfully ampli- Łazarski, G.

Academic Editor: Jianhua Zhu Received: 9 June 2015 / Accepted: 25 August 2015 / Published: 15 September 2015 Abstract: Background: The European continent is presently colonized by nine species of the genus Pulsatilla, five of which are encountered only in mountainous regions of southwest and south-central Europe. The remaining four species inhabit lowlands in the north-central and eastern parts of the continent. Most plants of the genus Pulsatilla are rare and endangered, which is why most research efforts focused on their biology, ecology and hybridization. The objective of this study was to develop genomic resources, including complete plastid genomes and nuclear rRNA clusters, for three sympatric Pulsatilla species that are most commonly found in Central Europe. The results will supply valuable information about genetic variation, which can be used in the process of designing primers for population studies and conservation genetics research. The complete plastid genomes together with the nuclear rRNA cluster can serve as a useful tool in hybridization studies. -

Ireland were contacted in January 2003 and asked whether they would like to participate in the Working Group to produce a new Red List. The core Working Group, from the first meeting held in February 2003, consisted of botanists in Britain who had a good working knowledge of the British and Irish flora and could commit their time and effort towards the two-year project. Other botanists who had expressed an interest but who had limited time available were consulted on an appropriate basis.
