Research Abstract

TILLING (Targeting Induced Local Lesions In Genomes) platform has been established in Micro-Tom cultivar, which is a model tomato cultivar for fruit biology. TILLING allows us to isolate mutants, which has mutations in gene of interests. Using the TILLING platform, ripening-related mutants were isolated and characterized, demonstrating the validity of the established platform.
