The DNA content of bundle sheath cells and mesophyll protoplasts from the C(4) plant pearl millet (Pennisetum americanum, Tift 23DB) was determined by microspectrophotometry to be 1.8 to 2.3 and 3.2 to 4.0 picograms/nucleus, respectively. Measurement of RNA by ultraviolet spectroscopy indicated that bundle sheath cells contain twice as much RNA as mesophyll cells.
