Similarities and differences in the microbial structure of surface soils of different vegetation types.

Background: Soil microbial community diversity serves as a highly sensitive indicator for assessing the response of terrestrial ecosystems to various changes, and it holds significant ecological relevance in terms of indicating ecological alterations. At the global scale, vegetation type acts as a major driving force behind the diversity of soil microbial communities, encompassing both bacterial and fungal components. Modifications in vegetation type not only induce transformations in the visual appearance of land, but also influence the soil ecosystem's material cycle and energy flow, resulting in substantial impacts on the composition and performance of soil microbes.

Ursane-Type Triterpenes with a Phenylpropanoid Unit from and Evaluation of Their Cytotoxic Activities.

Six new ursane-type triterpenes with a phenylpropanoid unit and five known oleanane-type triterpenes were isolated from the leaves of . The undescribed compounds were identified by analysis of 1D and 2D NMR and HRESIMS spectroscopic data as ptilospermanols A-F. The cytotoxicity of new compounds against six human cancer cell lines and three mouse tumor cell lines was evaluated by MTT assay.

Characterization of the complete chloroplast genome of (Rhizophoraceae).

(Rhizophoraceae) is an important economic tree species narrowly distributed endemic to East Asia. In this study, We generate the complete chloroplast genome of using next-generation sequencing technology, which is 162,052 bp in size and consists of a large single copy (LSC) of 89,556 bp and a small single copy (SSC) of 18,814 bp, separated a pair of inverted repeats (IRb and IRa) of 26,841 bp. The overall GC content is 36.

Physiological and comparative transcriptome analysis of the response and adaptation mechanism of the photosynthetic function of mulberry ( L.) leaves to flooding stress.

Flooding has become one of the major abiotic stresses that seriously affects plant growth and development owing to changes in the global precipitation pattern. Mulberry ( L.) is a desirable tree spePhysocarpus amurensis Maxim andcies with high ecological and economic benefits.

A new species of Leptobrachella Smith 1925 (Anura: Megophryidae) from Southern Guangxi, China.

We described a new species of the genus Leptobrachella from Southern Guangxi, China, based on morphological characteristics, molecular analyses and bioacoustics. This new species, Leptobrachella shiwandashanensis sp. nov.

First Report of Anthracnose Caused by Colletotrichum siamense and C. fructicola of Camellia chrysantha in China.

Camellia chrysantha (Hu) Tuyama, belonging to the Theaceae family, is famous for its large size and golden yellow flowers, which has high ornamental and health care functions (Mo et al. 2013). Anthracnose is one of the most important fungal diseases worldwide, causing serious economic losses to many plants.
