Summary: This study found non-concerted evolution of internal transcribed spacer (ITS) sequences in the genus Lycium, showing high levels of polymorphism. The ITS paralogues were identified as pseudogenes or functional copies, with distinct differences from their corresponding functional copies. The results suggest a link between the non-concerted evolution of ITS and recent divergence of tandem repeats within the Lycium genome and hybridization between species.

Summary: The GC content of the ribosomal internal transcribed spacer 2 (ITS2) undergoes GC-biased evolution, with higher GC content than the adjacent 5.8S regions. The GCs are distributed in a heterogeneous manner in the ITS2 secondary structure, with paired regions being larger than unpaired regions, indicating selection for thermodynamic stability. Homogeneous ITS2 sequences are always GC-rich, supporting GC-biased gene conversion (gBGC) and concerted evolution of ITS2.

Summary: The polymorph Allium pallasii s.l. from monotypic A. sect. Pallasia was studied using various methods, and it was found to be divided into two distinct species based on morphology, geography, cytology, and genetics. A. pallasii s. str. is found in North-East Kazakhstan, Western Siberia, and the Altai Mountains, while A. caricifolium is found in Kyrgyzstan, Northwest China, South-East Kazakhstan, and Zaysan Lake. Despite significant genetic differences, both species are sisters and are related to species of the A. sect. Codonoprasum (Subg. Allium). Allium caricifolium differs from A. pallasii s. str. in terms of taller stems, dense inflorescence, and longer filaments. The possible phylogenetic reasons for the separation of these species are discussed, and a nomenclature analysis of synonyms was conducted.

Summary: Ethylene induces anthocyanin biosynthesis in most fruits, but inhibits it in pears. The transcription factor PpERF105 activated the expression of PpMYB140, which then inhibited the anthocyanin biosynthesis in pears. The competition between PpMYB140 and PpMYB114 led to the formation of a complex that further inhibited anthocyanin biosynthesis.

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.
