Abstract
Expression of a class I patatin cDNA clone, SK24-1, in Escherichia coli revealed that the cDNA clone possessed lipid acyl hydrolase (LAH) activity. Transformed potato plants were obtained via Agrobacterium-mediated transformation using the chimeric constructs containing the sense and antisense cDNA under the control cauliflower mosaic virus 35S (CaMV 35S) promoter. In some sense transformed plants, both sense patatin RNA and LAH activity were increased and further resulted in a significant increase of percentage of plantlets that formed microtubers and numbers of microtubers per plantlet in vitro. All antisense plants displayed a reduction in LAH activity. Both sense and antisense RNA could be detected in antisense plants, but transcripts of antisense RNA resulted in a reduction of endogenous sense RNA. Moreover, expression of antisense cDNA in some antisense transformed plants led to a significant decrease in the number of microtubers formed. These results suggest that SK24-1 was involved in regulating microtuber formation. Key words: Patatin, potato, Escherichia coli, sense RNA, antisense RNA
