S the computation power and the memory capacity increase, the corpus-base speech synthesis system has become the best and most popular speech synthesis system. Based on the system, the linguistic features are first derived after the text is parsed, then some appropriate units are selected as candidates. Finally, the well-pronounced speech is synthesized by concatenating the best unit sequence by the synthesizer part of system.

The results implied that NO/ROS-induced ABA accumulation come from de novo synthesis pathway rather than degration of conjugated forms. The protein synthesis inhibitor actidone blocked the NO-induced ABA accumulation while having no effects on ROS-induced ABA accumulation, indicating that the action of NO was gene-expression dependent and that of ROS was gene-expression independent. These results suggested that NO may serve as a stress signal in the regulation of ABA-biosynthesis and ROS may serve as substrate in ABA biosynthesis or be involved in the regulation of enzyme activities.
1ABA合成抑制剂fluridone抑制ROS和NO诱导的ABA积累,表明NO/ROS诱导的ABA积累来源于ABA的从新合成而不是已有结合态ABA的代谢;(2)蛋白质合成抑制剂环己亚胺可以抑制NO诱导的ABA积累而对ROS诱导的ABA积累没有影响,说明NO的作用涉及基因表达而ROS的作用与基因表达无关,暗示NO的作用方式可能是作为一种干旱胁迫信号物质参与ABA合成的调节,而ROS则可能参与了相关酶活性的调节或直接参与了ABA合成的底物反应。
