Phytotoxic effects of Stellera chamaejasme L. root extract
The results demonstrated that the high concentration aqueous extracts from S. chamaejasme had strong phytotoxity on seedlings growth of tested species, and dicotyledonous plants (rapeseed and sesame) were more sensitive to  S. chAMAejame extract than monocotylingonous Plants (wheat and maize).

Water activity dependence of lipase catalysis in organic media explains successful transesterification reactions
The water activity dependence of lipase kinetics in organic media was evaluated using lipases from Rhizopus oryzae and Candida rugosa immobilised on polypropene EP-100. The conversion studied was theExpand
Hydrogel-based transparent soils for root phenotyping in vivo
A “transparent soil” formed by the spherification of hydrogels of biopolymers is described with high transparency, good mechanical stability, tunable pore sizes, low cost, and easy scalability, and allows for the imaging of unconstrained root systems in vivo by both photography and microscopy.

Antibacterial activity and mechanism of 36 Chinese herbs
The extracts from 36 kinds of Chinese Taibai herbs (CTHs) were obtained with the help of methanol and tested for antibacterial activity against four bacteria and two fungi inhibition through methodsExpand
[Bioactivity of the metabolites from endophytic actinomycete Fq24 against Tetranychus cinnabarinus].
An endophytic actinomycete strain Fq24 was isolated from healthy tomato plants and the main chemical component of fraction S11 was methyl hexadecanoate, whose molecular formula was C17H34O2, being one of the substances with acaricidal activity in the metabolites from F q24. Expand
[Identification of endophytic actinomycete St24 tomato plants from and its application in biocontrol of gray mold disease].
An endophytic actinomycete strain St24 with acaricidal activity was isolated from the root-stem junction of tomato plants and its taxonomic position and its control effect against gray mold disease investigated, showing that the extracts could protect tomato plants against B. cinerea. Expand
[Identification of endophytic Actinomycete Lj20 from plant and its antifungal substances].
Endophytic actinomycete Lj20 with antifungal activity was isolated from the roots of capsicum plants and synthesized its antif fungus substances, which were classified as Streptomyces rochei. Expand
Effects of rare earth elements on callus growth, soluble protein content, peroxidase activity and shoot differentiation of Echinacea angustifolia cultures in vitro.
The result from time-course experiment indicated that La3+ or Ce4- showed promotion on callus growth after 15 days cultured and Ce4+ displayed a better effect than La3+. Expand
