Repeated cases of allopatric divergence and secondary contact in cattail (Typha) speciation

This study uses genome-wide data to show that Typha species diverged allopatrically without gene flow, followed by secondary contact, with little evidence of ecological speciation driving differentiation.

Time in sympatry correlates with the strength of reproductive isolation in hybridising Typha

The paper uses genomic data to compare reproductive isolation between Typha species in Europe and North America, finding stronger isolation in Europe due to prolonged sympatry.

Development of genomic resources for cattails (Typha), a globally important macrophyte genus

The paper develops genomic resources for Typha, a wetland plant genus, by sequencing 140 samples and identifying SNPs and plastome sequences to study genetic diversity and hybridization.

A simple method to genetically differentiate invasive F1 Typha hybrids (T. x glauca) and advanced-generation/backcrossed hybrids from parent species (T. latifolia and T. angustifolia) in eastern Canada and northeastern USA

The paper presents five genetic markers to distinguish invasive Typha hybrids from parent species and advanced-generation hybrids in eastern Canada and northeastern USA.

Genome assembly, annotation and comparative analysis of the cattail Typha latifolia

The paper presents a high-quality genome assembly of Typha latifolia, along with annotation and comparative analysis, providing a resource for studying hybrid dynamics in Typha species.
