Screening of useful rice genes concerned with ultraviolet-B tolerance mechanisms by the Rice FOX Hunting System

Abstract

FOX Hunting System (full-length cDNA over-expresser gene-hunting system) was developed as a novel activation tagging system for searching useful genes. An advantageous feature of this method is no restrictions in species. The Rice FOX line, which each Arabidopsis line contains single rice full-length cDNA, was constructed. This unique tool will be utilized to isolate and analyze useful rice genes that are functionally unknown.
Ultraviolet-B (UV-B) radiation can damage plants and decreasing productivity. Genetic improvements of plant UV-B tolerance mechanisms may lead to enhancement of protective ability against harmful UV-B irradiation. In this study we try to screen useful rice genes concerned with UV-B resistance by using rice FOX hunting system. Obtained genetic resources will be useful to improve plants function against UV-B radiation and various stresses. This research is supported by the Special coordination funds for Promoting Science and Technology entitled Rapid identification of useful traits using rice full-length cDNAs.
