One new alkaloid consanguine B (1), together with 10 known alkaloids (2-11), were isolated from ethanol extract of the branches and leaves of Polyalthia obliqua Hook.f. & Thomson collected in the Hainan Province, China. Their structures were elucidated by the detailed analysis of comprehensive spectroscopic data. All compounds were evaluated for their cytotoxic activities. Compound 1 showed weak cytotoxic activities against Hela and MCF-7 human cancer cell lines.

The scarcity of natural citral has spurred interest in its alternative sources such as the essential oil-rich branches and leaves of citral balsam fir. This study assessed the impact of nitrate, ammonium, and amide nitrogen forms at varying concentrations on the growth, development, and soil bacterial diversity of 1-year-old Cinnamomum camphora ct. citral seedlings.

Nitrogen (N) is crucial for plant growth and stress resistance and is primarily absorbed and transported by nitrate transporters (NRT). , known for its strong salt-alkali stress resistance, and genes have rarely been reported. This study aims to identify and analyze the gene family to understand its composition, evolutionary patterns, and roles in salt stress responses.

Ethnopharmacological Relevance: Rhododendron dauricum L. leaves (RDL) are used in traditional Chinese medicine as a heat-clearing herb for pulmonary diseases. Our previous research suggested its anticomplement polysaccharides might help alleviate pneumonia, but their in vivo effects remain unreported.

Plant phenotypes exhibit high plasticity, with shoot branching as a prime example and a key factor influencing yield in many species. The availability of photosynthates is a critical determinant of shoot branching (or tillering in monocots). Carbohydrates, primarily in the form of sucrose, are synthesised in actively photosynthetic leaves (sources) and transported to non-photosynthetic tissues (sinks), such as tiller buds.
