Summary: DNA barcoding is used as an effective tool for rapid and accurate identification of plant species, including Orchidaceae which is the second largest family of flowering plants globally. By analyzing chloroplast genes, this study provides a theoretical basis for species identification, germplasm conservation and innovative utilization of orchids.

Summary: By analyzing DNA barcoding regions, this study identified 71 Vicia specimens of Eurasian descent. The trnL and ITS2 regions were effective in discriminating the analyzed species, while the rpoC1 region could not identify all selected species due to sequence conservation or missing sequences in GenBank. The combination of DNA barcoding regions is essential for accurate species discrimination within the Vicia genus.

Summary: Through comprehensive analysis of miRNAs in 81 plant species, we identified 8048 species-specific miRNAs. The study found that SS-miRNAs have a high turnover rate even over short evolutionary distances, and mature miRNAs have a striking difference in AU content compared to NSS-miRNAs. In addition, SS-miRNAs tend to be located close to or within genes and preferentially regulate functions related to diverse metabolic processes.

Summary: The study compared the properties of betaine lipids and phosphatidylcholine (PC) lipids through neutron diffraction experiments and dynamic molecular simulations. It found that betaine lipids are thicker and more rigid than PC lipids, and they have higher repulsive forces, possibly due to unscreened electrostatic contribution. Furthermore, betaine lipids can exist in both gel and fluid phases.

Summary: Rumen flukes are parasitic trematodes that impact domestic and wild ruminants worldwide. Accurate species identification is crucial for understanding their epidemiology and effects on hosts. A universal molecular approach using ITS-2 sequencing has shown promise for identifying rumen fluke species across various hosts and origins.

Summary: Accurate identification of pests and their natural enemies is crucial in pest management. Molecular identification, without requiring taxonomic expertise, is widely used in this field. However, there is a lack of systematic comparative studies on the selection of molecular markers. For Trichogramma, a commonly used parasitoid wasp, cytochrome oxidase subunit 1 (COI) and internal transcribed spacer 2 (ITS2) are the most frequently used markers. The superiority of either marker in Trichogramma molecular identification is still controversial.

Summary: Seed priming is a pre-germination treatment that induces mild stress to improve seed germination and plant growth in stressful environments. Stress memory, the phenomenon where exposure to sub-lethal stress improves responses to future lethal stresses, has gained attention recently. Both seed priming and stress memory invoke a 'bet-hedging' strategy in plants for better growth under stress.

Summary: The ovules and seeds of seed plants play crucial roles in reproduction and dispersal, with various tissues performing different functions in a limited space and requiring complex gene cascades. Some features are independent innovations, while others reflect morphological differences among lineages.

Summary: This study quantifies the joint effects of seed traits and phylogeny on species distribution and finds that seed mass, seed dispersal mode, and phylogeny significantly influence species geographic distribution. The findings highlight the importance of including seed traits and phylogenetic history in climate-based niche models to predict the response of plant geographic distribution to climate change.

Summary: The study focuses on the baculum of extinct species, which is a fossilizable part of the male genitalia and correlates with reproductive aspects. Fossil bacula are rare, with descriptions currently limited to two extinct canid species. This research describes the baculum of five extinct species of Borophaginae, revealing similarities to extant canids but with a unique ventral curvature. The implications of this curvature on the reproductive biology of these animals remains unknown.

Summary: This study provides comprehensive insights into the structural characteristics, expression profiles, and potential functions of the MATE gene family in wheat. It reveals the important roles of TaMATEs in aluminum tolerance through their interaction with citrate and subsequent transportation to alleviate aluminum toxicity. The findings contribute to our understanding of the mechanisms underlying plant response to adverse stresses.

Summary: This study establishes an effective identification method for species of Veratrum in Pimacao by utilizing ITS2 sequences and metabolomics methods. Two distinct subspecies in V. mengzeanum are reinforced and a new subspecies is collected in China for the first time. Non-targeted and pseudo-targeted analysis are used to identify steroidal alkaloids as potential markers for species differentiation. Statistical differences are found between subspecies of V. mengtzeanum and populations of V. taliense, V. mengtzeanum, and V. stenophyllum.

Summary: This paper investigates the wood species used in the wooden roof structures of the Florence Cathedral, identifying silver fir, chestnut, and elm as the most commonly used timbers. The technological implications of these woods on the cathedral's wooden structures are discussed, as well as the main sources of timber available to the builders.

Summary: In this study, the complete chloroplast genomes of four Liparis species were sequenced and analyzed, and their phylogenetic relationships with related species were evaluated for the first time. Highly variable regions were identified as potential DNA markers for species identification and phylogenetic studies. The phylogenetic analysis based on chloroplast genome sequences supported the polyphyly of Liparis and its subdivision into three branches.
