Development of a method for ozone-stress diagnosis in plant using ozone responsive genes

日本的大气污染问题已基本得到解决，但只有光化学氧化剂（臭氧）仍是污染物中浓度较高的一种，而且污染范围较广。其对植物包括森林和农产品的严重危害性以及对人类健康的影响引起了人们的强烈关注。本研究的目的是发展一种能准确、快速、简便地掌握环境臭氧对植物影响的胁迫诊断方法。建立一种以分子机制为基础的相对廉价的方法，旨在通过获得植物中臭氧响应基因表达的信息来评估田间生长的植物。

Most of problems in air pollutants have been dissolved in Japan; however, only photochemical oxidant (ozone) remains as the pollutant with higher density in wider area. Its serious harmful effects on the plant including the forest and farm products are strongly concerned about, as well as human health. The objective of this study was development of a method for stress diagnosis by which the effect of ambient ozone on plants can correctly, speedily and easily be grasped. The establishment of a relatively inexpensive method underpinned by the molecular mechanism was aimed for the application in assessment of field-grown plants by obtaining the information of ozone-responsive gene expression in plants.
