Fig. 1. Detection of the gamone 1 gene transcript. (A) Diagram of gamone 1 and synthesized probes. The box represents the gamone 1 ORF (from +1 to +915). The signal peptide cleavage site (+49) and the putative N-terminus of mature gamone 1 (+100) are indicated. Probes were prepared by labeling the fragment (probe 1) and full-length gamone 1 cDNA (probe 2) with DIG. (B) Transcription of gamone 1. Total RNA from mating type I cells was loaded in lanes 1-4 (2, 5, 11, 11 µg, respectively) and lane 5 (6 µg), and separated on a 1% denaturing agarose gel, transferred to a nylon membrane and then hybridized with probe 1 (lanes 1-4) or probe 2 (lane 5). A single band of about 1000 bases can be detected in each lane (arrowhead). The size of RNA markers (Novagen) is indicated on the left-hand side.
