Current Status of TILLING and EcoTILLING: TILLING and EcoTILLING technique have been adapted in diverse species including rice, maize, Lotus, poplar, Arabidopsis, wheat, barley, potato, tomato, sunflower, common bean, Field Mustard, clover, melon, pea, peanut, sorghum, rapeseed, soybean, melon, poplar, sugarcane, brassica and other for the purpose of gene detection, functional genomics, polymorphism assessment, plant breeding as described in case study part. Ecotilling: EcoTILLING is similar to TILLING, except that its objective is to identify natural genetic variation as opposed to induced mutations. Many species are not amenable to chemical mutagenesis; therefore, EcoTILLING can aid in the discovery of natural variants and their putative gene function This approach allows one to rapidly screen through many samples with a gene of interest to identify naturally occurring SNPs and / or small INs/DELS iTILLING: A new approach to the TILLING method that reduces costs and the time necessary to carry out mutation screening was developed for Arabidopsis and it is called iTILLING, individualized TILLING
