Characterization of a Novel Polysaccharide Derived from Rhizospheric and Its Mechanism for Enhancing Salinity Resistance in Rice Seedlings.

Soil salinity is an important limiting factor in agricultural production. Rhizospheric fungi can potentially enhance crop salinity tolerance, but the precise role of signaling substances is still to be systematically elucidated. A rhizospheric fungus identified as was found to enhance the salinity tolerance of rice seedlings.

Evaluation of negative effect of Naphthenic acids (NAs) on physiological metabolism and polycyclic aromatic hydrocarbons adsorption of Phragmites australis.

Toxic substances in the environment disturb the adsorption of pollutants in plants but little is known about the underlying mechanisms of these processes. This study evaluated the PAH adsorption by Phragmites australis under NAs stress. Results showed that Naphthenic acids (NAs) significantly decreased the adsorption of PAHs and had higher selectivity for type and structure.

A new chitosan sub-micron and encapsulated Iturin A with enhanced antifungal activity against Ceratocystis fimbriata and Rhizopus strolonifer.

Iturin A is a natural antifungal agent that is widely used in the agriculture and food industries. In the present study, a new modified chitosan sub-micron, succinaldehydic acid (SAC) - chitosan (CS) system was synthesised by microwave irradiation and then as a carrier for capsulation of Iturin A (SAC-CS-IA). The structures of SAC-CS and SAC-CS-IA were characterised by SEM, NMR and FTIR.
