Abstract

An antisense class I patatin gene under control of the CaMV 35S promoter was introduced into potato (Solanum tuberosum) cultivar E-potato 3 using the Agrobacterium tumefaciens system. PCR amplification and PCR–Southern blot analysis indicated that the antisense class I patatin gene had been integrated into the potato genome. Northern hybridization analysis showed that the antisense gene transcribed normally in the transgenic potato plants and resulted in a reduction of endogenous class I patatin mRNA. Total soluble protein content and lipid acyl hydrolase activity of microtubers, derived from transformed plants, decreased by a maximum of 36.4% and 31.4%, respectively, compared with control plants. The expression of this antisense gene also resulted in reductions of the plantlets forming tubers, tubers per plantlet and the effective tubers (≥50 mg) of the transformed plants.
