Summary: In this study, Hypochaeris radicata was used as a model species to investigate the functional morphology of the pollen-bearing style in Asteraceae. The results showed that the pollen-bearing style can catapult pollen to safe sites on pollinators' bodies, avoiding pollen waste. These findings provide important insights into the pollination strategy and floral design of Asteraceae.

Summary: Oligonucleotide (oligo)-fluorescence in situ hybridization (FISH) has become a new generation of FISH technique in plant molecular cytogenetics research. Chorus2 software effectively selects single-copy oligos, removes repetitive elements, and allows the development of FISH probes from plant species without an assembled genome, broadening its application in molecular cytogenetics research.

Summary: This study assembled and compared the chloroplast genomes of several Carthamus species, finding that their chloroplast genome structures were highly conserved. Phylogenomic analysis supported Carthamus as a monophyletic taxon, divided into two sections. This study expanded our understanding of Carthamus chloroplast genomes and provided support for more comprehensive phylogenetic studies.

Summary: AFLP analysis revealed genetic polymorphism among wabisuke camellia and its relative species, suggesting the two old 'Uraku' trees are asexually-propagated clonal strains. The genetic distance between wabisuke cultivars and Chinese camellias was greater than that between wabisuke cultivars and Camellia japonica. Wabisuke camellias can be classified into two subgroups based on their genetic characteristics.

Summary: The study found that UroVysion was the most sensitive method, with all methods having high specificity. Cytology, forceps biopsies, and fine needle aspiration were also proven to have certain sensitivity and specificity for detecting malignancy in pancreatobiliary strictures. The most effective approach to maintaining high sensitivity while preserving specificity was limiting malignant interpretation to cases with 5+ cells showing the same polysomic signal pattern and/or loss of one or both 9p21 signals.

Summary: Dubyaea DC. is a small genus of Asteraceae endemic to the Pan-Himalayan region, with poorly understood phylogenetic relationships. Results showed Dubyaea can be divided into three major clades, with biogeographic analyses indicating its late Miocene origin in the Hengduan Mountains and subsequent diversification in situ as well as spread to the Himalayas.

Summary: Oligonucleotides fluorescence in situ hybridization (Oligo-FISH) is an emerging technology used in research areas such as detection of chromosome variation, identification of allopolyploid, and deciphering of three-dimensional (3D) genome structures. Various tools for probe design have been developed to increase the specificity of oligo probes and enable genome-scale oligo probe design, but comprehensive comparison and evaluation of these tools is lacking.

Summary: By using phylotranscriptomic analyses on 244 transcriptomes and genomes of the sunflower family, this study provides insights into the distribution, origin, and evolution of biodiversity within the Asteraceae family. The results suggest that global climate shifts, whole-genome duplications, and morphological evolution have all played key roles in shaping the diversity of the Asteraceae family.

Summary: This study examines the systematic value of carpological traits in the taxonomically complex genus Valerianella. The results show that these traits are useful in classifying the genus at higher taxonomic ranks, but not at the species level for certain species pairs. Genetic data support the taxonomic classification at the sectional level, but reveal admixture for some species pairs. The study also describes a new section within the genus to accommodate a highly divergent species.

Summary: This study investigated the ovule, seed, and fruit development in six Bulbostylis species, revealing variations mainly in pericarp development within the genus. Contrary to previous studies, the results suggest conflicts in infrageneric groupings based on fruit micromorphology and molecular analysis of the Bulbostylis species. This work enhances understanding of reproductive anatomy and embryology in Bulbostylis and sheds light on the origin of multiple embryos in Cyperaceae.

Summary: This study investigated the chromosome evolution of Crepis plants by analyzing the chromosome base number and organization of rDNA loci in 39 species. The results showed that despite variations in rDNA loci organization, most species had rDNA loci on the same chromosome arm. Comparative analysis revealed multiple independent gains of rDNA loci and repositioning during diversification and speciation. These findings provide important insights into the evolutionary mechanisms and speciation of Crepis plants.

Summary: In this study, the fate of transposable elements (TEs) in Dactylorhiza allotetraploids formed through hybridization between diploid species D. fuchsii and D. incarnata was investigated. The results showed that the paternal genome had a higher content of LTR retrotransposons compared to the maternal genome, resulting in a larger genome size. The genome size and TE composition in the youngest allopolyploid appeared to be additive, while rampant genome expansion was observed in intermediate-aged polyploids. A non-autonomous tandem repeat element played a major role in the genome dynamics of the allopolyploids. Overall, the fate of repeats in this system was strongly regulated and predictable across multiple independent allopolyploidization events. Mild genomic shock was also observed following allopolyploidization, possibly due to strong selection against further genome expansions.

Summary: In this study, we investigated the colonization history of Saxifraga longifolia, a plant species abundant in the Pyrenees and rare in other Iberian mountains and the African Atlas. Our findings suggest that the current distribution is the result of the shrinkage of a more extensive distribution in previous cold periods. We also discovered seven plastid haplotypes, predominantly found in the Pyrenees, and inferred migration routes mainly from the Pyrenees to other areas.

Summary: This study presents a new and updated phylogenetic hypothesis on the evolution of the Capsicum genus, incorporating nearly all currently accepted species. The study proposes a new model of spatial diversification based on genome-wide analysis. The results suggest that the Northern and Central Andes were the likely ancestral range of Capsicum, and that the diversification of the genus began in the Pliocene and continued through the Pleistocene.

Summary: This study investigated the karyotype diversity and DNA C values of Dorstenia spp. from the Neotropical region and examined the genomic sequencing of African and Neotropical species. The results showed that polyploidy plays a significant role in karyotype differentiation, but there is no clear relationship between DNA C values and karyotype features or rDNA sites. Dysploidy events and rearrangements involving repetitive fractions are suggested to be responsible for chromosome number variations and changes in genome size.

Summary: This study examines the genetic structure, diversity, and genome-environment associations of two snowbed species in the Eastern Alps, and finds that they are suitable models for genetic monitoring of climate change adaptation along elevation gradients. The main effects of climate change on these species are changes in precipitation and sunlight exposure, leading to alterations in snow cover duration and encroachment of shrubs. Further research is needed to characterize and validate the genomic loci involved in adaptive processes by assembling genomes and studying larger sample sizes and time series.

Summary: Asymmetric meiosis leading to the release of pseudomonad pollen grains is a shared feature in Cyperaceae. This study analyzed the early- and late-diverging sedge genera Hypolytrum and Eleocharis, respectively, and compared them to other genera in the family. The results show variations in pseudomonad shape and positioning, with homologous development in Hypolytrum and unique traits in Eleocharis, but shared ultrastructural features among the genera.
