A, Theoretical restriction fragment lengths of PCR
product from the genomic DNA or cDNA. The structure of
Md-ACS1 is indicated as described in the
legend of Figure 1. The locations of the primers used in the PCR are
shown by arrows. H, HindIII site; (X),
ACS1-2-specific XhoI site.
B, Fragment lengths of HindIII/XhoI
double-digested PCR products. Lane M, φX174/HaeIII; lane
1, genomic DNA of cv Golden Delicious; lane 2, RT-PCR products from
climacteric cv Golden Delicious fruit; lane 3, RT-PCR product from
climacteric cv Fuji fruit.
