Next‐generation sequencing reveals hidden genomic diversity in glacial relicts: A case study of Meesia triquetra

Eva Mikulášková, Tomáš Peterka, Jakub Šmerda, Michal Hájek

Journal of Systematics and Evolution > 62 > 3 > 475 - 488

The recent development of genetic methods has facilitated the identification of cryptic species across different groups of organisms, including plants. However, next‐generation sequencing has rarely been used to study cryptic speciation in plants, especially in bryophytes, organisms with a dominant haploid life phase. The ability to capture variation across the whole genome makes this method an effective...

Jia‐Fu Chen, Yong‐Chao Xu, Juan Jiang, Xiao‐Min Niu, more

Journal of Systematics and Evolution > 62 > 3 > 358 - 367

Transposable elements (TEs) are prevalent components of diverse genomes, and play an important role on the genomic stability and expression regulation of their adjacent genes. It is interesting to know the variation of TE expression and the effects of the presence/absence of TEs on gene expression after hybridization. Here we assessed the expression variation of TEs and the impacts of TEs on expression...

Mechanisms of reproductive isolation between annual and perennial plants of Incarvillea sinensis

Wen‐Juan Lan, Fang‐Yuan Wang, Spencer C. H. Barrett, Wen‐Ting Wang, more

Journal of Systematics and Evolution > 62 > 3 > 548 - 560

Quantifying the relative strength of isolating barriers is a major focus of research on plant speciation. Contrasting life histories and mating systems have the potential to limit gene exchange between closely related populations growing in sympatry. However, few studies have quantified reproductive isolating barriers between conspecific annual and perennial populations and their contributions to...

A haplotype‐resolved genome for Rhododendron × pulchrum and the expression analysis of heat shock genes

Jian‐Shuang Shen, Lan Lan, Sheng‐Long Kan, He‐Feng Cheng, more

Journal of Systematics and Evolution > 62 > 3 > 489 - 504

Rhododendron is the largest genus in Ericaceae and is well known for its diversity and beauty of flowers present in different species, making it a much‐revered lineage of ornamental plants. Many species of Rhododendron are intolerant of high temperatures, which are becoming more common and intense in urban areas under global climate change. Therefore, the discovery and description of genes from heat‐tolerant...

Niche conservatism and strong phylogenetic signals in climate, soil, and morphological variation of Neotropical firs (Abies, Pinaceae)

Jorge Cruz‐Nicolás, Norberto Martínez‐Méndez, Erika Aguirre‐Planter, Luis E. Eguiarte, more

Journal of Systematics and Evolution > 62 > 3 > 368 - 383

Interspecific trait divergence may reflect adaptation and reproductive isolation, particularly after the rapid differentiation that may follow the colonization of new environments. Although new lineages are generally expected to be morphologically and ecologically similar to their ancestors, environmental forces can also drive adaptive differentiation along specific phenotypic axes. We used climate...

Linked selection and recombination rate generate both shared and lineage‐specific genomic islands of divergence in two independent Quercus species pairs

Yong Shi, Biao‐Feng Zhou, Yi‐Ye Liang, Baosheng Wang

Journal of Systematics and Evolution > 62 > 3 > 505 - 519

A fundamental question in speciation genomics is how evolutionary processes shape the genomic landscape of differentiation between species. Regions of elevated differentiation, referred to as genomic islands, could be shared among closely related species (shared islands) or specific to a lineage (lineage‐specific islands). Shared islands are typically assumed to result from background selection. However,...

Xie‐Ting Wu, Jun‐Wu Shu, Su‐Xin Yin, Eva‐Maria Sadowski, more

Journal of Systematics and Evolution > 62 > 3 > 449 - 456

Parrotia C. A. Meyer (Hamamelidaceae) is a relictual genus with only two extant species disjunctly distributed in the subtropical forests of East China and temperate forests of North Iran. Fossil records suggest that Parrotia was widespread in Europe and Asia during the Miocene, but its fossils are predominantly based on pollen and leaves. In this paper we describe the first fossil flower of Parrotia...

Reinterpreting the phylogenetic position and taxonomic revision of the genus Pterocyclus (Apiaceae, Apioideae) based on nrITS, complete plastid genome, and morphological evidence

Xian‐Lin Guo, Wei Gou, Megan Price, Qiu‐Ping Jiang, more

Journal of Systematics and Evolution > 62 > 3 > 384 - 402

The classification of species in the genus Pterocyclus has been a topic of concern, as they were initially considered members of Pleurospermum (Apiaceae) in the Flora of China. However, the intergeneric and infrageneric classifications of Pterocyclus and its allies, such as Hymenidium and Pleurospermum, have been controversial. To address these issues, we performed phylogenetic analyses using one...

Zhi‐Hua Zeng, Qian Yu, Qing‐Hong Feng, Xin‐Jia Wang, more

Journal of Systematics and Evolution > 62 > 3 > 438 - 448

The adaptive significance of phenotypic differences between females and males can provide insights into sex‐specific selection and the evolution of sexual dimorphism. Dioecious plants commonly exhibit sexual dimorphism in height, although its ecological and evolutionary significance have rarely been examined experimentally. Here, we investigate the functional consequences of the temporal reversal...

Palynological and macroscopic characters evidence infer the evolutionary history and insight into pollination adaptation in Impatiens (Balsaminaceae)

Yong‐Xiu Song, Tian Hu, Shuai Peng, Yi‐Yan Cong, more

Journal of Systematics and Evolution > 62 > 3 > 403 - 420

The genus Impatiens comprises more than 1000 species and displays enormous morphological diversity. As a taxon that is notoriously difficult to classify morphologically, the taxonomic significance of pollen morphology has been discussed in previous studies. However, there was only limited study on the evolution of palynological and macroscopic character in this genus before. In this paper, we observed...
