A, Northern-blot hybridization using the
full-length T106 probe of 10 μg of total RNA of 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, and 6 h. B, Location of the ankyrin
repeats on clone T106 and of the deleted sequence on clone T91. The
region selected as specific probes for T91 or T106 and resultant
fragments degraded by RNase A are indicated as solid lines. C,
Difference in signal patterns in the RNase protection assay applied to
total RNA of the zygote at 4 h with either specific probe. D,
Survey of the temporal expression patterns of Zys3 mRNA
by the RNase protection assay using the partial sequence specific for
cDNA clone T91. HincII-digested φX174 DNA was used as
a molecular marker.
