Application of TILLING in plant improvement.
TILLING (Targeting induced local lesions in genomes) is a general reverse-genetic strategy that is used to locate an allelic series of induced point mutations in genes of interest. High-throughput TILLING allows the rapid and cost-effective detection of induced point mutations in populations of chemically mutagenized individuals. The technique can be applied not only to model organisms but also to economically important organisms in plants. Owing to its full of advantages such as simple procedure, high sensitivity, and high efficiency, TILLING provides a powerful approach for gene discovery, DNA polymorphism assessment, and plant improvement. Coupled with other genomic resources, TILLING and EcoTILLING can be used immediately as a haplotyping tool in plant breeding for identifying allelic variation in genes exhibiting expression correlating with phenotypes and establishing an allelic series at genetic loci for the traits of interest in germplasm or induced mutants.
