Summary: Parasitic life-strategies in the phylum Nematoda are diverse and complex. Through analyzing novel rDNA data, this study reveals the paraphyly of a major taxon and the independent emergence of marine parasitism in certain lineages. It also presents molecular data on marine nematodes from unicellular hosts, highlighting the independent origins of exploitative nematode associations at a microscopic scale. The study suggests that non-intestinal host capture is a primary route for the transition to parasitism in roundworms.

Summary: This study delved into the delimitations and evolutionary relationships of Cycas species in Sri Lanka through an island-wide survey. The researchers analyzed morphological features, genetic markers, and DNA sequence data to identify three Cycas species in Sri Lanka. The study also revealed the presence of C. circinalis in Sri Lanka for the first time and identified intermediate individuals with mixed morphological and genetic characteristics. The authors suggest the combined analysis of morphology and DNA sequence data as a superior method for distinguishing closely related Cycas taxa.

Summary: This review focuses on the genetic and regulatory mechanisms of inflorescence branching in grasses, primarily based on data from rice and maize. The placement and development of primary branches are controlled by conserved auxin regulatory genes, while subtending bracts are repressed by a network of genes including TASSELSHEATH4. Axillary branch meristems are regulated by signaling centers adjacent to the meristems themselves. The production of spikelets is governed by gradients of SQUAMOSA-PROMOTER BINDING-like and APETALA2-like proteins and their microRNA regulators.

Summary: This paper describes a new species, Primula longipilosa, from SW Yunnan, China, and discusses its systematic placement based on molecular analysis. It is morphologically similar to P. mollis, but differs in its racemose inflorescence, green calyx tube, pink to pink rose corolla, stamens at 1/3 length above the base of the corolla tube, and applanate globose capsule.

Summary: In this study, whole-genome resequencing of 90 accessions from the Choche germplasm bank was performed, resulting in the identification of genetic markers such as SNPs and InDels. The SNPs discovered in this study may contribute to the variation in important agronomic traits in coffee. Additionally, the resequencing data and genetic markers identified provide insight into the genetic variation of coffee germplasm and enable a wide range of genetic studies.

Summary: Alisma L. is a genus of aquatic and wetland plants with ten known species. Different ploidy levels have been observed, including diploids, tetraploids and hexaploids. Molecular phylogenetic analyses suggest that two closely related species in East Asia and one species endemic to Japan were generated from diploid progenitors, possibly through an evolutionary event in Japan. Species delimitation analysis revealed that A. orientale is distinct from the widespread A. plantago-aquatica and is apparently endemic to Southeast Asia.

Summary: The present study investigated the phylogeny, phylogeography, and morphological variability of the Lotus dorycnium complex across its distribution range. The results showed some degree of differentiation in morphology, and analyses based on nuclear and plastid DNA revealed a tendency towards geographic differentiation. The study also revealed the possibility of rare gene exchange between the L. dorycnium complex and L. graecus group for the first time.

Summary: In this study, Ziziphora taxa grown in Turkey and around the world were analyzed using molecular and morphological methods. The results suggest that Ziziphora is a monophyletic genus and provide evidence for rearrangements and new taxa. Additionally, the study presents a revised status of Ziziphora taxa in Turkey based on molecular systematic analysis.

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: Species delimitation of European blind mole rats is challenging due to their small morphological differences and complex chromosomal evolution. This study provides a comprehensive framework to improve understanding of their evolutionary history and revise their taxonomy. The results reveal the presence of multiple superspecies and species, with distinct geographic patterns and rapid chromosomal evolution.

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.
