Abstract
The Translationally Controlled Tumor Protein (TCTP) is a multifunctional protein found in most eukaryotic taxa. In plants, TCTP regulates cell-cycle progression as well as programmed cell death and is involved in plant regeneration and responses to abiotic and biotic stress, among other functions. Additionally, there is evidence that the transcript and protein are transported over long-distance. Potatoes are a crop of agricultural interest that can reproduce asexually by regeneration from stolons and tubers. Therefore, in this study the effect of transient expression of Solanum tuberosum TCTP (StTCTP) on tuberization was analyzed. StTCTP mRNA was shown to be transported long-distance. Additionally, transient overexpression of StTCTP resulted in tuber bearing shoots with a greater diameter compared to control plants. Furthermore, the early stages of tuberization were induced compared to control plants, in which only mature tubers were observed.
