近5年增强UV-B辐射对植物影响的研究进展

综合分析了近5年增强UV-B辐射对植物影响的最新研究进展.结果发现近5年来增强UV-B辐射对植物影响的研究明显具有以下趋势:1)增强UV-B辐射对植物个体影响的研究总体上趋于减少;2)对植物信号转导的研究日益增多;3)植物对增强UV-B辐射胁迫的防卫机制和伤害修复研究仍是重点,但更偏重于防卫机制方面的研究;4)更加重视对植物群体及生态系统影响的研究;5)增强UV-B辐射与其它因子(环境背景因子和污染胁迫因子)的复合作用研究成为新的热点和重点.根据近5年的研究进展,推断在今后一段时间内,有关增强UV-B辐射对植物和生态系统影响的研究还会加强,信号转导、分子水平机理以及增强UV-B辐射与其它因子的复合作用研究可能是今后的研究热点.

Trends in Effects of Enhanced UV-B Radiation on Plants in Recent Five Years

Trends in the effects of enhanced UV-B radiation on plants in recent five years were reviewed in this paper. The following is noteworthy: 1) studies on the effects of the enhanced UV-B radiation on individual plant have been gradually decreased in the mass; 2) researches on signal transduction induced by UV-B have gradually become the new emphases and hotpots; 3) researches on plant recovery and repair induced by UV-B injuring is still the hotspot, but more attention has been paid to the defense mechanism; 4) studies on the effects of UV-B radiation on plant were focused on the plant population and ecosystems; 5) combination effects of enhanced UV-B radiation with other factors will be the new research focus. It is concluded that the studies on effects of UV-B radiation on plants and ecosystems will be intensified; and signal transduction, molecular level mechanism and the combination effects of UV-B with other factors will be the new hotpots in the future.
