Abstract The genus Chenopodium L. is characterized by its wide geographic distribution and ecological adaptability. Species such as quinoa ( Willd.) have served domesticated staple crops for centuries. Wild species exhibit diverse niche adaptations are important genetic reservoirs beneficial agronomic traits, including disease resistance climate hardiness. To harness the potential of wild taxa crop improvement, we developed a pangenome through assembly comparative analyses 12 that encompass...
A widespread but controversial idea in ecology states that the number of invaders a species assemblage depends on its richness. Both negative and positive relationships have been reported. We examined whether simple neutral model where assemblages are generated by drawing individuals from two pools identical (native alien) can predict this relationship. performed meta-analysis published data The showed communities with low fixed numbers individuals, relationship between aliens native is...
Vegetative regeneration of individual genotypes Asian Reynoutria taxa, which are invasive in the Czech Republic, was studied R. sachalinensis (five genotypes), japonica (a single genotype present country), and their hybrid ×bohemica (nine genotypes). Identity confirmed by isozyme analysis. Ten rhizome segments each were planted a randomized block design. After 30 d, rate measured as proportion rhizomes that produced shoots. Emergence time final mass shoot recorded. The significantly affected...
Genetic admixture is supposed to be an important trigger of species expansions because it can create the potential for selection genotypes suitable new climatic conditions. Up until now, however, no continent-wide population genetic study has performed a detailed reconstruction events during natural expansions. To fill this gap, we analysed postglacial history Alnus glutinosa, keystone European swamp habitats, across its entire distribution range using two molecular markers, cpDNA and...
Reticulate evolution is characterized by occasional hybridization between two species, creating a network of closely related taxa below and at the species level. In present research, we aimed to verify hypothesis allopolyploid origin hexaploid C. album s. str., identify its putative parents estimate frequency allopolyploidization events. We sampled 122 individuals aggregate, covering most distribution range in Eurasia. Our samples included progenitors str. both ploidy levels, i.e. diploids...
Abstract: Questions: 1. How does species richness of recipient communities affect Reynoutria invasion? 2. invasion change host community structure? 3. Are there any differences in habitat preferences among three closely related taxa? 4. the genetic structure populations along course a river? Location: River Jizera basin, north Bohemia, Czech Republic. Methods: Nine 0.25 km 2 plots were chosen river. Within each plot all main types determined and sampled using Braun‐Blanquet scale to...

Satellite DNA (satDNA) is the most variable fraction of eukaryotic genome. Related species share a common ancestral satDNA library and changing any component in particular lineage results interspecific differences. Although general developmental trend clear, our knowledge origin dynamics satDNAs still fragmentary. Here, we explore whole genome shotgun Illumina reads using RepeatExplorer (RE) pipeline to infer family life stories genomes Chenopodium species. The seven diploids studied...
The genus Reynoutria is represented by four taxa in the Czech Republic: japonica var. japonica, R. compacta, sachalinensis and xbohemica. By using flow cytometry, cytological variability within described based on 257 samples. varieties of are cytologically uniform, exclusively octoploid (2n = 8x 88) compacta occurs only as a tetraploid 4x 44), but xbohemica exhibit some variation chromosome numbers. predominantly 4 x also occasionally hexaploid cytotypes. most common ploidy level 6x 66),...
Summary Atriplex sagittata , an arly succesional, annual species of disturbed habitats in Central Europe, produces three types fruits. We studied the differences dispersal between fruit order to investigate their ecological roles. The typical positive relationship ability and germinability is not found this species. Type A (ebracteate) fruits produced deeply dormant seeds had lowest potential, but two with bracts, type B, seeds, was better dispersed by both water wind than C, which...
Background and Aims Polyploidy in plants has been studied extensively. In many groups, two or more cytotypes represent separate biological entities with distinct distributions, histories ecology. This study examines the distribution origins of Alnus glutinosa Europe, North Africa western Asia. Methods A combined approach was used involving flow cytometry microsatellite analysis 12 loci 2200 from 209 populations species modelling using MIROC CCSM climatic models, order to analyse (1) ploidy...
Summary We reconstructed the historical pattern of postglacial biogeographic range expansion boreal tree species Alnus incana in Europe. To assess population genetic structure and diversity, we performed a combined analysis nuclear microsatellite loci chloroplast DNA sequences (65 populations, 1004 individuals). Analysis haplotype diversity revealed that southeastern refugial populations situated Carpathians Balkan Peninsula did not spread north cannot be considered as important source for...
