| Abstract: | The novelest reports about enhanced UV-B irradiation caused by changes of the environments on a global scale leading to the responses of plant to a variety of signal pathways were discussed in the present work.Furthermore,the mechanisms of signal conduetion were reviewed,including UV-B receptors,signal molecule cascade, such as reactive oxygen species,salicylic acid,jasmonic acid,ethylene and nitric oxide and so on,and effects of increased UV-B stress on activities of gene expression.Then,the cascade model of signal molecule was put forward about UV-B stress signal conduction. Accordingly,the summary may have provided some theories and methods for effective protection plant cell from the damage of UV-B enhancement caused by changes of the global environment. |
