Genetic Diversity and Structure of Northern Populations of the Declining Coastal Plant Eryngium maritimum
2019
Abstract Genetic diversity among 13 northern populations of the declining coastal plant Eryngium maritimum L. at the northernmost extent of the species distribution range was studied using retro-transposon-based SSAP molecular markers. Diversity indices varied extensively among populations; some showing extremely low diversity whereas other populations exhibited moderate amounts of genetic variation. Differentiation among populations was highly variable as well. Interestingly, differentiation among northern populations was not influenced strongly by geographic distance. Closely situated populations were often more divergent than more distant populations suggesting other factors may be respo…

Chemical Composition of the Essential Oils of Three Species of the Apiaceae Family Growing Wild in Sicily: Bonannia graeca, Eryngium maritimum and Op…
2013
n the present study the chemical composition of the essential oils from aerial parts of Bonannia graeca (L.) Halácsy and Opopanax chironium (L.) Kock, and from aerial parts and roots of Eryngium maritimum L. was evaluated by GC and GC-MS. α-Pinene (15.2%) and β-pinene were recognized as the main constituents of B. graeca, whereas the aerial parts of O. chironium contained mainly the diterpene cembrene and the coumarin angelicin. In both aerial parts and roots of E. maritimum germacrene D (10.4% and 15.9%, respectively) and 2,4,5-trimethylbenzaldehyde (8.3% and 6.7%) were the most abundant components
The influence of sea currents, past disruption of gene flow and species biology on the phylogeographical structure of coastal flowering plants
2009
Aim We investigate the geographical genetic structure of two coastal plant species, Cakile maritima Scop. (Brassicaceae) and Eryngium maritimum L. (Apiaceae), through three sea straits and along one continuous stretch of coast using amplified fragment length polymorphisms (AFLPs). The two species have a similar ecology in that they grow in sandy habitats, but differ in life-form (annual vs. perennial) and dispersability of seeds by sea water as inferred from floating experiments. The sea straits differ in their geological history and their modern current systems. The primary goal of our study was to test the hypothesis that sea straits have an influence on the geographical patterns of genet…
Development of retrotransposon-based SSAP molecular marker system for study of genetic diversity in sea holly (Eryngium maritimum L.)
2010
Eryngium maritimum L. is a wild plant species threatened or endangered in most of Northern Europe, where species is on the northern margin of its distribution range. Recent studies have found reduction of size and even extinction of many populations. Assessment of genetic diversity in natural populations of endangered wild plant species can reflect condition and fitness of particular population and inform decisions on appropriate conservation measures. Application of inter simple sequence repeat markers and chloroplast DNA sequencing could not resolve genetic relationship between E. maritimum populations in Northern Europe. Therefore, the more sensitive retrotransposon-sequence-specific amp…
Terrestrial growth and marine dispersal? Comparative phylogeography of five coastal plant species at a European scale
2005
The phylogeography of five flowering plant species (Cakile maritima, Eryngium maritimum, Salsola kali, Halimione portulacoides, Crithmum maritimum) widespread along the European coasts was investigated across their entireEuropean range using AFLP evidence. Both similarities and dissimilarities were found. All species contain a distinct Black Sea/Aegean Sea cluster, and all except E. maritimum contain a distinct Adriatic Sea cluster or group of genetically very similar clusters. All species except Cr. maritimum contain a distinct Atlantic Ocean/North Sea/Baltic Sea cluster clearly separate from the Mediterranean material. In Ca. maritima a distinct Baltic Sea subcluster was found. In the wes…
Historical biogeography in a linear system: genetic variation of Sea Rocket (Cakile maritima) and Sea Holly (Eryngium maritimum) along European coasts
2000
The exclusively coastal Cakile maritima and Eryngium maritimum represent a linear biogeographical system. Genetic variation among 25 individuals of C. maritima and 16 individuals of E. maritimum, from the coasts of Europe, North Africa and the Canary Islands, was analysed using random amplified polymorphic DNAs (RAPDs) and intersimple sequence repeats (ISSRs). Genetic distances (Dice) were calculated and used to investigate the correlation between genetic and geographical distances, to construct Neighbour Joining (NJ) trees, and to compare mean genetic distances between areas within and across species. Genetic distances and geographical distances measured along the coast are well correlated…

Seed dormancy and germination of an endangered coastal plantEryngium maritimum(Apiaceae)
2013
INTRODUCTION Eryngium maritimum L. is a littoral species growing on sand dunes and shingle beaches. Although it is listed among the species widespread in western and southern Europe, overall its population is declining (Van der Maarel & Van der Maarel-Versluys, 1996). The species is included in the Red Data Book of Latvia (Fatare, 2003) and is protected in several other European countries. In northern Europe and in the Baltic Region it grows near the limits of its current area of distribution and therefore is at a greater risk of extinction because in small and isolated populations there is a risk of inbreeding depression. For example, in Eryngium alpinum partial self-incompatibility causes…
Augu audu kultūru izmantošana retās piekrastes sugas Eryngium maritimum bioloģijas pētījumos
2022
Jūrmalas zilpodze (Eryngium maritimum L.) ir Latvijā reti sastopama un apdraudēta augu suga. Pēdējās desmitgadēs sugas izplatības areāla ziemeļaustrumu daļā zilpodzes indivīdu skaits un izplatība ir samazinājies. Par galveno iemeslu tam uzskata problēmas ar ģeneratīvo vairošanos. Ar anatomiskās izpētes palīdzību secināja, ka zilpodzes saknes satur veģetatīvās vairošanās struktūras. Audu kultūru eksperimentos noskaidroja, ka zilpodzes sakņu ievadīšanai piemērotākā apstrāde ir ar HgCl2, bet zilpodzes pavairošanai un apsakņošanai piemērotākā ir Murashige & Skoog barotnes modifikācija ar pievienotu 6-benzilaminopurīnu. Lai pārliecinātos par audu kultūrā ilgstoši uzglabāta zilpodzes materiāla ģe…
