After NMDA stimulation, he concentrations of Ca~2+ and NO in both nuclear and plasma rise observably, especially in the netlike structures; the change of Ca~2+ concentration in nuclear is larger than that in plasma,however the changes of NO concentration in nuclear and plasma are similar. We also observed comparative increases of the concentration of Ca2+ and NO in neurodendrite after NMDA stimulation.

The results showed that: the explants of strawberry leaves were rather sensitive to kanamycin, and the corresponding concentration of 20 mg/L could substantially inhibit the growth of non-transformed tisse and be used to screen the leaves of strawberry after transformation. Timentin at the concentration of 300 mg/L could be used to eliminate Agrobacterium tumefaciens and had minor impact on the growth of the explants. The preculture time of 2-4 days was beneficial to improve transformation frequency. Co-culture for 2-3 days not only had higher gus transient expression but also avoid the over-growth of agrobacterium. The bacterial concentration of OD(subscript 600nm) 0.4 was the best inoculum density and 10 minutes was the best inoculation time.
