The present study describes the molecular authentication of 21 Korean Artemisia species using PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) technique based on the trnL-F sequences in chloroplast DNA. Five different banding patterns were generated from 21 Artemisia species using HinfI restriction enzyme. A. apiacea, A. keiskeana and A. sieversiana have specific banding patterns. The remaining 18 species had shared two banding patterns. Phylogenetic analysis based on trnL-F sequence variations showed results similar to PCR-RFLP banding patterns. It suggested that the trnL-F region does not have sufficient variations to identify the 21 Artemisia species. However, the specific banding patterns for A. apiacea, A. keiskeana and A. sieversiana can be utilized as a DNA marker for discriminating them from other Artemisia species. These markers will be also useful for developing A. apiacea, A. keiskeana and A. sieversiana into new medicine and food based on their efficacy.

To understand the distribution pattern and influencing factors of plant community and diversity along the altitude gradient, we examined plant community types, plant diversity and phylogenetic diversity of mountain steppe in Luoshan, Ningxia, and analyzed the relationship between the plant community and its diversity and environmental driving factors. The results showed that the main community types in the mountain steppe were community, community, community, community, + community, community, ++ community, + community, + community, community, community and community. The distribution of mountain steppe community was mainly affected by altitude, soil alkali-hydrolyzed nitrogen, water content, available potassium, silt and organic matter contents, with altitude and soil water content having the greatest effects (<0.

For non-hibernating species within temperate climates, survival during severe winter weather often depends on individuals' behavioral response and available refugia. Identifying refugia habitat that sustains populations during adverse winter conditions can be difficult and complex. This study provides an example of how modeled, biologically relevant snow and weather information can help identify important relationships between habitat selection and dynamic winter landscapes using greater sage-grouse (Centrocercus urophasianus, hereafter "sage-grouse") as a model species.

More than 2 000 yeast strains isolated from 1 200 samples mostly collected from Tibet and Yunnan provinces in China were identified as 462 species according to the internal transcribed spacer including the 5.8S rDNA (ITS) and the D1/D2 domains of the large subunit rDNA (LSU) sequence analyses. Among them, 70 new basidiomycetous yeast species were proposed based on the multi-locus phylogenetic analyses including the D1/D2 domains, the ITS, the small subunit rDNA (SSU), the largest subunit of RNA polymerase II (), the second largest subunit of RNA polymerase II () and translation elongation factor 1-α (), as well as the phenotypic comparisons.

Introduction: Morocco is home to a remarkable diversity of flora, including several species from the Artemisia genus. This study aims to thoroughly examine the chemical composition of essential oils derived from Artemisia species and assess their antibacterial and antioxidant properties through in vitro experiments and in silico simulations.
Methods: Samples of Artemisia herba-alba Asso.

Plant interference is a key factor influencing plant coexistence and species composition. The two primary forms of plant interference-allelopathy and resource competition-are often difficult to separate. This study conducted an outdoor pot experiment to quantify the distinct contributions of resource competition and allelopathy of on seedling growth of three species: , , and .
