“…These SSR markers should be useful for identifying hybrids and introgressed individuals in North American cattail populations because (1) our samples were collected over a broad geographic area (31 populations in six states), (2) most F 1 hybrid individuals had one diagnostic SSR allele from each parent, as expected, (3) putative hybrids and hybrid derivatives had intermediate phenotypes, as expected, and (4) analyses carried out in separate laboratories gave consistent results. Further analyses of the genetics of hybridizing populations could be carried out using cytoplasmic markers to determine the maternal parents of naturally occurring progeny from interspecific crosses (e.g., Kuehn et al, 1999; Zhang et al, 2008).…”

“…Many previous attempts to classify Typha species have resulted in the adoption of a loosely defined and intuitive approach to taxonomy, based largely on field observations and incorporating the analysis of some micromorphological characters (Hotchkiss & Dozier, 1949;Finlayson & al., 1985). The delimitation of Typha species based on morphology alone is often not possible Zhang & al., 2008) due to the high degree of plasticity among the morphological characters. Therefore, a number of molecular markers (e.g., randomly amplified polymorphic DNA [RAPD], amplified fragment length polymorphism [AFLP], or sequence information of nuclear and ptDNA) have been used for Typha species delineation, at least as a supplemental tool Zhang & al., 2008;Na & al., 2010).…”

Species identification and analysis of phylogenetic relationships within the genus Typha are difficult because of the high degree of variability among morphological characters and frequent interspecific hybridization. Traditionally, two sections (T. sect. Ebracteolatae and sect. Bracteolatae) have been recognized within the genus based on the presence or absence of bracteoles in the female flowers. The aims of this study were to reconstruct the phylogeny of Typha using DNA sequence data from nuclear LEAFY and three plastid regions, and to evaluate previous classifications. We sampled nine species from various regions that were each invariant at the molecular level. A parsimony consensus tree recovered three clades in the genus: clade I including T. angustifolia, T. elephantina, T. domingensis, and T. capensis; clade II including T. orientalis and T. laxmanni; and clade III comprising T. latifolia and T. shuttleworthii. Typha minima was found sister to the rest of the Typha species with maximal bootstrap support. The results do not support previous classifications of Typha. Character analysis showed that bracteole loss, spatulate stigma, lack of a gap between staminate and pistillate inflorescences, and monad pollen are derived characteristics in Typha.

“…Molecular identification has been successfully used to solve the problems of species delimitation, genetic relationships, and the determination of hybrid origins in taxonomically difficult groups (Zhang et al 2008;Kim et al 2010aKim et al , 2012. A high level of genetic variation in the markers used is required for delimitating species and for determining the relationships among the species.…”

Molecular identification of Schoenoplectiella species (Cyperaceae) by use of microsatellite markers

Over the past few decades, use of molecular markers for species delimitation has drastically increased. Schoenoplectiella Lye has been recognized as a taxonomically difficult genus because of its morphological simplicity and frequent interspecific hybridization. The main objective of this study was to clarify the taxonomic identities of eight Schoenoplectiella species by use of molecular markers. We also evaluated the genetic relationships among S. 9 trapezoidea, known as a natural hybrid, and its close relatives. We used six microsatellite markers for 44 individuals from 31 natural populations of eight Schoenoplectiella species in South Korea. Six microsatellite marker combinations generated 59 amplification-detectable bands, of which 33 were specifically detected in one or more individuals of each species. Cluster analysis revealed that the grouping was consistent with the taxonomically recognized species. Our results do not support the hybrid origin of S. 9 trapezoidea. Rather, they suggest that this species is more closely related to S. hotarui. The informative microsatellite markers enabled us to clarify the distinctions among Schoenoplectiella species from South Korea and to identify the genetic relationships among these species. The molecular signatures found suitable for accurate identification of Schoenoplectiella species can be reliably used for studies of the phylogeny and evolution of this genus.
