 There are several opportunities for the applications of RNAi in crop science for its improvement such as stress tolerance and enhanced nutritional level . RNAi will prove its potential for inhibition of <unk> to enhance the productivity of C3 plants . This knockdown technology may be useful in inducing early flowering , delayed ripening , delayed senescence , breaking dormancy , stress @-@ free plants , overcoming self @-@ sterility , etc .
