Effect of Zm4CL1 mutations on 4CL enzyme activities. Crude enzyme extracts were prepared from the midribs of B73, bm5-504I, and bm5-504J. The 4CL enzyme activities of the above crude enzyme extracts against p-coumarate, caffeate, and ferulate were determined. Midribs of the fourth leaves were collected from 60-day-old B73 wild-type and bm5 mutants
