Rapid growth in living standards and leisure time has increased the demand for leisure facilities, and concentration of cities and environmental pollution have created more demand for green space. Now people think of forestry more as the space for rest and leisure than as that for wood production, The demand for the forestry of the city people, who want to escape from the routine, has exploded and will continue to grow. Forestry Administration started to develop 'forest for recreation' in 1988. As of December 1999, it has designated about 176 places as forest for recreation, 83 of which have been already completed. The government mobilized the people in an unprecedented afforestation campaign to plant trees in the barren hills and mountains at the beginning of the national foundation. The successful campaign has brought dense woods back, Beautiful valleys and natural ecology have recovered its value as tourism resources. The natural forest for recreation has created variety of benefits for general public. It helps individuals to relax and thus increase productivity and living standard. It has helped to meet the demand for leisure not only as a place of out-door activity but as a place for nature exploration. It also helps to enhance the underdeveloped economy and cultural standard of remote isolated villages. Short history of recreation forest uncovered a lot of problems in the areas of development, management and operation, which requires urgent attention.

It is well known that NtMEK2, a tobacco MAPK kinase, is the upstream kinase of both salicylic acidinduced protein kinase and wound-induced protein kinase. In addition, expression of NtMEK2DD, a constitutively active mutant of NtMEK2, is known to induce multiple defense responses in tobacco. In this study, transgenic rice plants that contained an active or inactive mutant of NtMEK2 under the control of a steroid inducible promoter were generated and used to determine if a similar MAPK cascade is involved in disease resistance in rice. The expression of NtMEK2DD in transgenic rice plants resulted in HR-like cell death. The observed cell death was preceded by the activation of endogenous rice 48-kDa MBP kinase, which is also activated by Xanthomonas oryzae pv. oryzae, the bacterial blight pathogen of rice. In addition, prolonged activation of the MAPK induced the generation of hydrogen peroxide and up-regulated the expression of defense-related genes including the pathogenesis-related genes, peroxidases and glutathione S-transferases. These results demonstrate that NtMEK2 is functionally replaceable with rice MAPK kinase in inducing the activation of the downstream MAPK, which in turn induces multiple defense responses in rice.
