　The 6^th International Symposium on Plant Responses to Air Pollution and Global Changes was held in Tbukuba Center for Institutes and EPOCHAL TSUKUBA, 'Isukuba, Japan, October 19-22, 2004. This symposium in Japan has been proposed by the late Alan R. Wellburn, who was in the past one of the major moderators of this symposia series. The aim of the symposium is to bring together scientists of various disciplines, who are actively involved in research on the impacts of gaseous air pollutants and global change on plant functioning and growth from molecular to ecosystem scales. The previous symposia were held in Oxford, UK, 1982 (1^st), in Munich, Germany, l987 (2^nd), in Blacksburg, USA, 1992 (3^rd), in Egmond aan Zee, The Netherlands, 1997 (4^th) and in Pulawy, Poland, 2001 (5^th).
　This special issue is one of three issues (a volume published in Springer and special issues of Phyton and Journal of Agricultural Meteorology) and contains a selection of contributed papers to the symposium. The papers were peer reviewed under session or topic editors. The publication has been executed with a grant from the Commemorative Organization for the Japan World Exposition('70).
