Summary: This study attempted to address the taxonomy and phylogeny issues of the Betula L. genus using nucleotide sequences and secondary structure analysis. While the phylogenetic trees generated from different methods were mostly consistent, the markers used still lack sufficient resolving power.

Summary: This study focused on the cultured cyanobacterial diversity in two geothermal environments of northern Costa Rica. It identified several potential new species within known genera, and suggested the presence of three possible new genera in their collection. The thermal springs of Miravalles and Las Lilas were found to be reservoirs of novel phylogeographic lineages of phototrophic microorganisms, indicating unique biodiversity in these environments.

Summary: This study aims to document the succession of shrub-herb communities after large-scale human disturbance and investigate the impact of changing environmental conditions on species replacement. The results show that species dominance increased while species richness decreased, with a decline in herbaceous plants and an increase in shrub height, cover, and biomass. Additionally, soil organic matter, total nitrogen, total phosphorus, and total potassium increased significantly, while pH declined. The findings indicate that climate, soil, and plant attributes are important drivers of post-disturbance succession, and the close relationship between vegetation and soil under local climatic conditions should be considered for effective management of the fragile ecosystem.

Summary: By comparing and analyzing the secondary and tertiary structures of 18S rRNA in twelve pentatomoid families, it is found that the shapes of the secondary and tertiary structures of the length-variable regions (LVRs) are highly informative for phylogenetic analysis. Based on these results, it is suggested that Thaumastellidae should be maintained as an independent family within the superfamily Pentatomoidea, rather than being a part of the family Cydnidae. Furthermore, the analysis also indicates a close relationship between Sehirinae and Parastrachiidae, expressed in morpho-molecular synapomorphies in the predicted secondary and tertiary structures of the length-variable region L (LVR L).

Summary: Recent research revealed that the previously thought similar Tenebriella actually belongs to a new genus and is capable of forming prominent microbial mats. Molecular phylogenetics analysis identified unique morphological and ecological characteristics of Tenebriella, leading to the recognition of two new species within this genus.

Summary: In this study, the genetic and molecular characteristics of ginseng were analyzed, resulting in the development of a mini-core collection representing the genetic variation of ginseng. Transcriptome sequencing revealed the wide molecular diversity of ginseng, and analysis of ginsenoside content showed extensive variation and correlation. The relationships between cultivars and landraces were also examined in terms of gene expression, gene variation, and ginsenoside biosynthesis.

Summary: The identification of unnatural residues that stabilize polyproline type 2 (PPII) folds can aid in the design of peptidomimetics targeting PPII-binding domains. N-aminoglycine (aGly) is found to be an effective PPII promoter. Further derivatization of an aGly-containing peptide affords N'-alkylated analogues with increased helical propensity. Backbone N-amination of glycine represents a convenient approach to stabilize PPII conformation and allows for the diversity-oriented synthesis of optimally constrained folds.
