“…Travis et al (2010) showed that backcrosses do exist in natural populations. The results of Snow et al (2010) also confirmed that hybrid populations can include substantial numbers of backcrossed genotypes. Most recently, studies by Kirk et al (2011) imply that the Typha glauca hybrid is not universally sterile, as suggested by Smith (1987), and that the levels of putative backcrossing found in their study exceed those discovered by Travis et al (2010) in the western Great Lakes region, which suggests that levels of backcrossing may be non-uniform across different areas of the Great Lakes.…”

“…F 1 hybrids do not usually produce seeds or backcross to the parental species and are considered to be highly sterile. However, evidence of backcrossing in Ontario (Kirk et al, 2011) and Michigan (Snow et al, 2010) indicates that hybrids are fertile and that hybrid populations can include substantial numbers of backcrossed genotypes. As described by Snow et al (2010), most of the backcrossed/advanced generation plants were more similar to Typha angustifolia, while a few were more related to Typha latifolia.…”

“…Conflicting theories still persist that propose to explain the hybrid nature of Typha glauca, although it is generally accepted to be a form of a hybrid between T. latifolia and T. angustifolia. Mostly Typha glauca has been described as a hybrid species and an F 1 hybrid (Bayly & O'Neill, 1971;Lee, 1975;Smith, 1987;Smith, 2000;Snow et al, 2010), or as a species produced by an introgression (Fassett and Calhoun, 1952;Lee, 1975). Moreover, the going assumption until recently was that Typha glauca occurred only as F 1 progeny of T. latifolia and T. angustifolia as F 1 hybrids were considered to be almost universally sterile (Marsh, 1962;Smith, 1987Smith, , 2000.…”

Typha glauca Godron and its parental plants in Poland: taxonomic characteristics

Natural interspecific hybridization between Typha latifolia L. and Typha angustifolia L. was analyzed by morpho-anatomical and molecular methods to determine whether the hybrid Typha glauca Godr. is present in Poland and to identify the best diagnostic traits for its identification. Eighty-three samples of the Typha species were collected. Nine random amplified polymorphic DNA (RAPD) primers provided 12 fragments specific for T. angustifolia and eight fragments specific for T. latifolia. DNA of all sampled individuals was analyzed with 20 diagnostic RAPD markers. The morpho-anatomical variability of T. glauca F 1 was found to be quite similar to that observed in parental plants. All of the 41 traits examined in the hybrids overlapped with those observed in the parents, however, the hybrids were visibly closer to T. angustifolia than to T. latifolia. The most discriminate characteristics were the length and pedicel width, as well as the epidermal cell thickness located above vascular bundles in leaf blades. Moreover, preliminary observations of seed sculpture showed that the length of testa cells could also be used to identify T. glauca. Clusters and the hybrid index (for molecular and morphological data) were highly coincident and support the hybridization hypothesis.

“…Nevertheless, introgression or backcrossing can only be properly studied using variable codominant microsatellite markers (e.g. Snow et al 2010).The finding that the genotypes of some of the plants morphologically similar to B. maritimus, had admixtures of B. planiculmis genotypes (e.g. in populations B and HU), may account for some irregularities and changes in plant occurrence.…”

Ecological hybrid speciation in central-European species of Bolboschoenus

Divergent natural selection is known to facilitate speciation in many taxa. The genus Bolboschoenus (Cyperaceae) is a model group for investigating ecological and homoploid hybrid speciation. Four taxa of Bolboschoenus occur in central Europe: the halophyte B. maritimus and glycophytes B. laticarpus, B. planiculmis and B. yagara. These species differ in their ecological niches. Such ecological and/or geographical isolation is critical for homoploid hybrid speciation. The determination of species of Bolboschoenus is based on morphological characters of the inflorescence and on achene shape and anatomy. On the basis of its intermediate morphology, chromosome number and ecological amplitude B. laticarpus is thought to be a hybrid. In order to determine the validity of morphological species and the possible hybrid origin of B. laticarpus we used amplified fragment length polymorphisms (AFLPs) as molecular markers and compared different genetic groups defined using STRUCTURE analysis with morphological data. The morphological classification of central-European species of Bolboschoenus was confirmed. Plants of heterogeneous genotypes were also found to be intermediate individuals resulting from spontaneous hybridization. Hybrid origin of B. laticarpus, which is genetically and morphologically intermediate between B. yagara and B. planiculmis, was elucidated. Inflorescence characters were less important for determining species than anatomical characters of achenes (widths of the exocarp and mesocarp).K e y w o r d s: AFLP, Bolboschoenus, central Europe, hybridization, model-based clustering, morphometrics, speciation IntroductionThe evolutionary histories of groups of closely related species of plants have been the focus of interest of much research in recent years, especially the process of speciation (Kaplan et al. 2013, Kolář et al. 2014, 2015. Moreover, questions concerning reproductive isolating mechanisms and the genetics and genomics of speciation have been highlighted by a major European initiative as the main subjects for further research (Butlin et al. 2012). Ecological speciation is one of the main modes of speciation (Schluter 2001). It occurs as a result of reproductive isolation due to divergent selection of organisms in different environments and can arise even where species occur sympatrically (Sobel et al. Preslia 89: 17-39, 2017 17 doi: 10.23855/preslia.2017.017 2009). Studying microevolution within groups of closely related species differing in ecology may thus reveal the role of such environmental differences in their origin. Hybridization can result in both gene flow among plant taxa and generation of new species. Some families and genera have relatively high numbers of hybrids, with the family Cyperaceae being one of them (Ellstrand et al. 1996).The European species of Bolboschoenus (Asch.) Palla (Cyperaceae) provide an example of a putative hybrid complex for which ecological selection, geographic isolation and hybridization are thought to have been important in their speciation, with the...

Species‐specific SSR alleles for studies of hybrid cattails (Typha latifolia×T. angustifolia; Typhaceae) in North America

Abstract: We provide the first documentation of backcrossed plants in hybridizing cattail populations in Michigan. The diagnostic SSR loci we identified should be extremely useful for examining the evolutionary and ecology interactions of hybridizing cattails in North America.
