The objective of the present research is searching plant mutants related to photoinhibition tolerance, using a 2D chlorophyll fluorometer.Control plants and mutation induced plants were photoinhibited in high light condition, and the extent of photoinhibition was evaluated by a 2D fluorometer. Target plants which have significantly different tolerance to photoinhibition were searched.About 7000 plants were screened and 118 mutant candidates were found. Detailed phenotyping of these mutants will lead to identification of genes related to photoinhibition tolerance. This will contribute to the elucidation of the mechanisms of photoinhibition and photoprotection.
