Temporal expression pattern of Zys3 proteins.
Total protein samples of C. reinhardtii vegetative
mt+ (V+) and mt−
(V−) cells, mt+ (G+) and
mt− (G−) gametes, and zygotes at 0, 10,
and 30 min and 1, 2, 4, 6, and 22 h were fractionated, blotted,
and probed with α-Zyspept3. Strong signals were detected in the
vicinity of 40 kD at 2, 4, 6, and 22 h. A slightly heavier minor
band that appeared at the same time may be the Zys3 precursor
containing the signal peptide.
