mutant corn (IMAGE) Penn State Caption Fluorescent tagged transgenic corn was used to detect abnormal protein accumulation in mutants. The top left image shows three cobs in bright light, and the top right image shows the same three ears in blue light. The presence and absence of green fluorescence help to easily identify mutant seeds. The bottom images show protein accumulation in control (left) and mutant (right) developing seeds.
