Tolerance to multiple abiotic stresses is mediated by interacting CNGC proteins that regulate Ca influx and stomatal movement in rice.

Members of the cyclic nucleotide-gated channel (CNGC) proteins are reportedly involved in a variety of biotic and abiotic responses and stomatal movement. However, it is unknown if and how a single member could regulate multiple responses. Here we characterized three closely related CNGC genes in rice, OsCNGC14, OsCNGC15 and OsCNGC16, to determine whether they function in multiple abiotic stresses.

[Study on enzyme-solvent extraction process of flavonoids from leaves of Ginkgo biloba].

Objective: To study the optimum enzyme-solvent extraction conditions of flavonoids from leaves of Ginkgo biloba.

Methods: To optimize the process by single factor experiments and orthogonal test according to the yield of flavonoids.

Results: The optimum extraction conditions were established as follows: pH 5.
