The role of transcription factor StBEL11 in carbon allocation and tuberization in cultivated potato differs from that known for the model Andean genotype.

Abstract excerpt

The transcription factor StBEL11 is known as a negative regulator of tuberization in the Andean potato (Solanum tuberosum ssp. andigena). This study focuses on its role in the common potato ssp. tuberosum by analysing transgenic lines of cv. Kamýk with down-regulated StBEL11 expression. As expected, these lines showed enhanced tuber induction on nodal segments cultivated in vitro on high-sucrose medium. However,...
