“…By synthesising available genetic data, we add to a growing body of evidence that shows that some invasive species do not experience genetic bottlenecks or extensive inbreeding (e.g. Roman and Darling, 2007;Mohammed et al, 2020). Based on the present analysis, we can also confidently conclude that no genetic paradox exists for any of the Australian acacias we studied and that standing genetic variation is similar in native and invasive populations.…”

Background and Aims Invasive species may undergo rapid evolution despite very limited standing genetic diversity. This so-called genetic paradox of biological invasions assumes that an invasive species has experienced (and survived) a genetic bottleneck and then underwent local adaptation in the new range. In this study, we test how often Australian acacias (genus Acacia), one of the world’s worst invasive tree groups, have experienced genetic bottlenecks and inbreeding. Methods We collated genetic data from 51 different genetic studies on Acacia species to compare genetic diversity between native and invasive populations. These studies analysed 37 different Acacia species, with genetic data from the invasive ranges of 11 species, and data from the native range for 36 species (14 of these 36 species are known to be invasive somewhere in the world, and the other 22 are not known to be invasive). Key Results Levels of genetic diversity are similar in native and invasive populations, and there is little evidence of invasive acacia populations being extensively inbred. Levels of genetic diversity in native range populations also did not differ significantly between species that have and that do not have invasive populations. Conclusion We attribute our findings to the impressive movement, introduction effort, and human usage of Australian acacias around the world.

“…This indicates the need to introduce more wild genotypes into breeding programs of daylilies to extend the gene pool. A similar problem is seen in other plants: Nebulo [36], Oryza [37], Lycoris [38], Rhododendron [39], and Narcissus [40] species to overcome the bottleneck of low genetic diversity and gene flow. Increasing genetic variation in daylily breeding programs by adding modern cultivars and early hybrids and species could ensure the diversity of new cultivars.…”

This work aims to characterize the genetic diversity of species, early hybrids, and cultivars using microsatellite simple sequence repeat (SSR) markers, as well as analyze and identify the origin of Hemerocallis spp. early hybrids. For this research, samples were collected from different types of daylily species, early hybrids (known or hypothetically first-generation hybrids from Hemerocallis species), foreign, and Lithuanian varieties. An initial screening of SSR primers developed for Hemerocallis citrina was performed, and their suitability for testing other daylily species and hybrids was evaluated. The genetic diversity was assessed with the selected eight-primer set, and molecular SSR profiles were created. Primer SAU00097 is the most informative according to heterozygosity (0.95) and polymorphism information content (PIC) (0.17). The highest heterozygosity was observed in Lithuanian cultivars (0.713), the lowest in species (0.583). Genetic relationships between species show that only fulvous daylilies are separated into a different cluster. The highest variation among genotypes was observed in the species group (18%), while modern cultivars had the slightest variation among genotypes (1%). The putative origin of early hybrids was analyzed using a likelihood heatmap of all genotypes. Results show what species might be used in breeding for early hybrids. Several modern diploid and tetraploid daylily cultivars have triploid species as ancestors.

“…Our combination of primers produced a similar amount of loci as those previously reported for blackberry Rubus spp. (Morillo et al, 2005), the guava Psidium guajava (Sanabria et al, 2006), the gulupa Passiflora edulis f. edulis (Fonseca et al, 2009), the foraging tree Trichanthera gigantea (Posso et al, 2011), the citrus rootstocks (Gallego et al, 2017), the Moringa oleifera tree (Chaves-Bedoya et al, 2017), the oil palm Elaeis guineensis (Castañeda-Cardona et al, 2018), in Zea mays (Alfalahi et al, 2019), and 5 Narcissus species (Mohammed et al, 2020). Given the absence of molecular studies in C. moritzianus, the number of loci generated by the 5 RAMs primers of this work (n = 81) resulted adequate to estimate genetic parameters and other statistical analyzes (Nybom & Bartish, 2000).…”

Nevertheless, because morphological characters are highly influenced by the environment (phenotypic plasticity) and plant phenology (Arnold et al, 2019;Gianoli & Valladares, 2012), molecular characterizations and the use of DNA markers, which is environmentally independent, are an alternative approach to assess plant genetic variation (Alfalahi et al, 2019;Ansari et al, 2015).…”
