Summary: Rare evidence shows that whole genome duplication (WGD) can break down reproductive barriers and facilitate gene flow. Recent studies in wild Arabidopsis species indicate that WGD can be adaptive and specific in response to challenges, primarily due to relative dosage of parental genomes in the endosperm. Some polyploids can act as adaptable 'allelic sponges', responding better to challenging environments.

Summary: The study found that snowtrouts exhibit similar evolutionary patterns in different habitats, possibly due to parallel selective pressures causing convergence of genetic variation. Different patterns of mixed evolution may exist during secondary contact. The results indicate that despite hybridization, morphological adaptations are retained, and the degree of admixture varies across tributaries, possibly influenced by environmental or anthropogenic factors.

Summary: Gene flow between species in the genus Arabidopsis is significant and may be achieved through polyploidization. However, polyploidization poses challenges due to genomic instabilities. In this study, an autoallohexaploid population was created by crossing diploid Arabidopsis thaliana with allotetraploid Arabidopsis suecica. Genome resequencing revealed two major mechanisms promoting stable genomic exchange in this population. Legitimate meiotic recombination and chromosome segregation between autopolyploid chromosomes of A. thaliana genomes occurred without a bias for parental origin, while occasional exchanges between homoeologous chromosomes were tolerated. These mechanisms may facilitate gene flow and stable introgression in natural populations.

Summary: A recent study found that the number of reported hybrid zones in plants is low compared to the tendency of plants to hybridize. The study suggests six potential factors, including lack of spatial and genetic structure, hybridization between non-closely related species, variability of plant hybrid zones over time, botanists' perception of hybridization, and insufficient population genetic data, to explain this phenomenon.

Summary: Polyploidy refers to having more than two sets of chromosomes. It can be artificially induced in plants through various methods, leading to increased gene scope and expression, impacting yield and product quality. Experimentally induced polyploid germplasm is a valuable tool for understanding gene expression, but challenges related to genome and epigenome stability need to be addressed.

Summary: The Pteris fauriei group, widely distributed in Eastern Asia, exhibits a complicated evolutionary relationship and rich genetic diversity. The presence of hybrid taxa adds to the morphological complexity and taxonomic difficulties of this group. Hybrids have broader ranges and more populations compared to parental taxa, showing divergent phenotypes and ecological fidelities. Apogamy, a form of asexual reproduction, is common in this group and contributes to its sustainability.

Summary: This research is the first comprehensive analysis of the intra-generic relationships within the subfamily Cryptogrammoideae, using molecular phylogenetic studies, scanning electronic microscopy, and herbarium data. The study revealed the deep divergence of Coniogramme merillii within the Coniogramme superclade, as well as the separateness of several Coniogramme and Cryptogramma species. The spore ornamentation was found to have diagnostic value in the recognition of cryptogrammoid taxa at the generic and section level.

Summary: This study examines the relationships among major subclades in the fern family Pteridaceae using phylotranscriptomic methods and a curated approach. It finds that Pteridoideae and Parkerioideae are sister to the rest of Pteridaceae, and Cryptogrammoideae is sister to Vittarioideae plus Cheilanthoideae. The study also provides evidence of several whole-genome duplication events within Pteridaceae, mainly in Vittarioideae and Cheilanthoideae, as supported by phylotranscriptomic analyses, cytological data, and genomic distributions of substitutions per site.

Summary: Micronesian islands taxa exhibit high levels of endemism, but little is known about their biogeographical histories. Recent increase in molecular biogeographic data allowed researchers to answer fundamental biogeography questions for the first time, confirming the importance of long-distance dispersal mechanisms for plant propagules. This study identified dominant dispersal scenarios for the Micronesian biota and reconstructed historical dispersal patterns from source areas estimated between the Eocene and the Miocene to dispersal into Micronesia between the Miocene and the Pleistocene.

Summary: The north temperate region had a warm climate and a rich thermophilic flora before the Eocene, but the early diversifications of the temperate biome under global climate change and biome shift are not well understood. Hybridization/introgression is an important driving force of speciation in plant diversity. In this study, we analyzed genomic data from the New World Vitis, a temperate North American flora, and found strong evidence for widespread incongruence and reticulate evolution among nuclear genes within both recent and ancient lineages.

Summary: By reconstructing the transcriptome-based phylogeny of 19 diploid Ephedra species, the evolutionary history of the gymnosperm genus Ephedra was investigated. The results revealed that Ephedra originated from Mediterranean species and split into three clades: American species, E. rhytidosperma, and other Asian species. Reticulate evolution was found to be common in Ephedra, and the genus likely originated in the late Cretaceous along the Tethys coast.

Summary: This study investigated the taxonomy of the crustose lichen genus Calvitimela using molecular phylogenetics and morphological observations. The results revealed evolutionarily old and deeply divergent lineages within Calvitimela, with overlapping morphological characters between different subgenera. Chemical characters were informative at the level of subgenera but often homoplastic at the species level. A practical taxonomy of Calvitimela was proposed based on these findings.

Summary: This study investigates the evolutionary history and speciation mechanisms of montane potamids in the Hengduan Mountains Region. The results suggest that the vicariance events of these crabs are correlated with the emergence of sky islands due to the uplift of the mountains. The mountain ridges provided corridors for their dispersal and past climatic conditions played a crucial role in their evolutionary history. The mechanisms isolating sky islands are reinforced by the climatic features of dry-hot valleys and continue to affect local diversification.

Summary: This study investigates the phylogenetic relationships among patellogastropod families using mitochondrial and phylogenomic data. The results show that the mitochondrial phylogeny recovers monophyly of most families, but the relationships among families are still contentious. However, a more robust family-level topology consistent with morphology is achieved by phylogenomics. Additionally, the mainly deep-water families are found to be monophyletic, suggesting a single colonization of the deep water during the Jurassic.

Summary: Despite numerous studies on hybrid speciation, our understanding of this process remains limited. In this study, we conducted an 18-year systematic investigation on Populus taxa on the Qinghai-Tibet Plateau and discovered three new taxa that originated from distant hybridization between two different sections. These hybrid taxa demonstrate greater ecological adaptability than their ancestral species due to heterosis. We propose a hybrid speciation process model that can explain important evolutionary concerns.

Summary: Unlike conspicuous ochrophytes, many small and overlooked flagellates belonging to basally branching stramenopiles remain poorly characterized at the cellular or genomic level. This study describes four new species, including two new genera, of sediment-dwelling MAST-6 and provides updated phylogenomic tree of stramenopiles. The characterization of these flagellates is important due to their phylogenetic diversity and abundance in various environments.

Summary: Phylogenomic conflicts are widespread among genomic data, with most previous studies primarily focusing on nuclear datasets instead of organellar genomes. In this study, we investigated the phylogenetic conflicts within and between plastid and mitochondrial genomes using Potentilla as a case study. We found that both plastid and mitochondrial genomes divided Potentilla into eight highly supported clades, with two newly identified clades. Our results demonstrate that mitochondrial genes can fully resolve phylogenetic relationships among major clades of Potentilla and are not always linked with plastomes in evolutionary history.

Summary: Traditionally, differences between species have been associated with morphological variation. However, the discovery of cryptic diversity suggests that the evolution of distinct lineages can occur without morphological differences. Through genetic analysis, we found that a tropical montane plant lineage is composed of numerous unrecognized genetic groups that are not morphologically distinct. Geographic distance and topography play a crucial role in determining the genetic divergence of these groups.
